CONCLUSION.517 This matter comes before the Court upon an Amended Complaint brought by Plaintiff Securities and Exchange Commission (“SEC”) against Defendants Kenneth D. Pasternak (“Pasternak”) and John P. Leighton (“John”) (collectively, “Defendants”). The SEC alleges that Defendants, as supervisors and senior executives of Knight Securities, L.P. (“Knight”), a registered broker-dealer firm, violated certain provisions of the Securities Act of 1933 (“the Securities Act”) and the Securities Exchange Act of 1934 (“the Exchange Act”). From May 13, 2008 to June 2, 2008, the Court conducted a non-jury trial. After the SEC rested its case, on May 30, 2008, Defendants moved for a judgment on partial findings pursuant to Federal Rule of Civil Procedure 52(c). The SEC opposed the motion. The Court reserved decision on the motions and heard additional arguments on the issue on June 12, 2008. After careful consideration of the extensive record before it, the Court sets forth herein its findings of facts and conclusions of law pursuant to Federal Rule of Civil Procedure 52(a), and finds in favor of Defendants. I. BACKGROUND A. Procedural History This case inquires into Knight’s “market making” business and the actions of one of Knight’s institutional sales traders, Joseph Leighton (“Joseph”) — John’s brother. In particular, the SEC focused its claims on forty-two trades executed by Joseph in 1999 and 2000 on behalf of “buy-side” institutional firms, such as mutual funds and investment advisors. All of the complained-of trades occurred in the NASDAQ Stock Market (“NASDAQ”). During the relevant time period, John, as head of Knight’s institutional sales desk, supervised Joseph, while Pasternak held ultimate supervisory responsibilities as Knight’s CEO and Chairperson of the Board of Directors. Based on Defendants’ status as supervisors at Knight, and John’s familial relationship with Joseph, the SEC, on August 8, 2005, filed a complaint, which they subsequently amended on March 30, 2006. The Amended Complaint asserts five counts against Defendants. In Count I, the SEC alleges that Defendants aided and abetted “Knight’s violation of Section 10(b) of the ... Exchange Act ... and Rule 10b-5 thereunder[.]” (Amended Complaint (“Am. Cmplt.”) ¶¶ 72-74 (citing 15 U.S.C. § 78j(b); 17 C.F.R. § 240.10b-5)). In Count II, the SEC asserts that Defendants violated Section 17(a) of the Securities Act. (Am. Cmplt. ¶¶ 75-77 (citing 15 U.S.C. § 77q(a))). In Count III, the SEC alleges that Defendants aided and abetted Knight’s violation of Section 15(c)(1)(A) of the Exchange Act. (Am. Cmplt. ¶¶ 78-81 (citing 15 U.S.C. § 780(c)(1)(A))). In Count IV, the SEC claims that Defendants aided and abetted Knight’s violations of Section 17(a) of the Exchange Act and Rule 17a-3 thereunder. (Am. Cmplt. ¶¶ 82-85 (citing 15 U.S.C. § 78q(a); 17 C.F.R. § 240.17a-3)). Finally, the SEC alleges in Count V that Pasternak is jointly and severally liable, pursuant to the “control person liability” set forth in Section 20(a) of the Exchange Act, for Knight’s violations of Sections 15(c)(1)(A) and 17(a) of the Exchange Act, as well as Rule 17a-3. (Am. Cmplt. ¶¶ 86-87 (citing 15 U.S.C. §§ 78o(c)(l), 78q(a), 78t(a); 17 C.F.R. § 240.17a-3)). Throughout the trial, the SEC offered varying theories of liability. In the Amended Complaint, the SEC alleges: Joseph Leighton, Knight’s most prolific sales trader, engaged in a pattern of fraud by trading for Knight’s institutional customers using a method that concealed from the customer the manner in which not held orders were worked, including the use of a delayed execution scheme and the improper use of ACT [ (Automated Confirmation Transaction Service) (“ACT”) ] modifiers, which obscured the quality of the execution price, resulting in profits above the industry norm at effectively no risk to Knight. (Am. Cmplt.¶ 18). As a result, the SEC submits that “Joseph Leighton failed to make full and appropriate disclosures and failed to provide best execution for orders placed by the institutional customers.” (Am. Cmplt.¶ 18). During the trial, the SEC expressed that this pattern of fraud amounted to improper front-running; that is, Joseph, upon receipt of an institutional order, would take a position in the ordered security and delay the execution of the order to take advantage of fluctuating market conditions, thereby generating profits that the SEC deems improper. (Trial Transcript (“Tr.”) 487:15-493:3). The SEC further alleges that Defendants knew of, or were reckless in not knowing of, Joseph’s fraud. (Am. Cmplt. ¶ 46). The Commission claims Defendants participated in the perpetration of this fraud by misstating to Knight’s customers and the public that Knight provided “best execution” and failing to disclose “the manner in which [Joseph] priced executions to customers.” (Am. CmpltV 47). During the trial, the SEC explained that John and Pasternak owed an independent fiduciary obligation to disclose to Knight’s institutional customers Joseph’s profits, and the failure to so inform the customers breached their fiduciary duties. The SEC further argued that Pasternak made a false and misleading statement by signing Knight’s 1999 and 2000 Form 10-Ks, which stated that Knight provided its customers with best execution. Finally, the SEC alleges that institutional sales traders at Knight, including Joseph, misused ACT modifiers, causing inaccurate and untimely reporting of trades to NASDAQ, and that Defendants knew of this systematic misuse. (Am. Cmplt.lffl 66-70). Based on those allegations, the SEC seeks injunctive relief, as well as statutory damages and disgorgement. Specifically, in the form of injunctive relief, the SEC requests that the Court permanently enjoin Defendants from future violations of the Securities Act and the Exchange Act, from aiding and abetting any future violations of the Exchange Act, and “from controlling any person that is in a position to violate Exchange Act Sections 15(c)(1)(A) and 17(a) and Exchange Act Rule 17a-3[.]” (Am. Cmplt.¶¶ (I)-(III)). During a fifteen-day bench trial, the Court provided both parties with the opportunity to present evidence. The SEC proffered the following witnesses from Knight: Gregory Cavallo, Carmine Curra, Thomas Fedele, David Miller, Anthony Mi-trano, Kenneth Ackerman, Alan Levinson, John Hewitt, John Howard, and Pasternak. The Commission also proffered the following fact witnesses representative of Knight’s customers: Andrew Brooks, Robert Marcotte, William Lawlor, Stuart George, Scott Thornton, William Schubert, Francine Smith, Kurt Smith, Margaret Mace, and William Perry. The SEC offered as a summary witness, Stephen P. Glascoe, in addition to the testimony of three experts: James Cangiano, Richard Gunter, and Daniel Levy, Ph.D. However, on May 23, 2008, upon Defendants’ motion in limine, the Court found that Richard Gunter could not properly testify as an expert in the field of “market making and institutional trading.” As a result, the Court precluded Gunter’s testimony. In response, Defendants presented in their case-in-chief the testimony of one witness: Leonard Amoruso, Knight’s Global Chief Compliance Officer at the time Joseph allegedly engaged in the fraudulent behavior. At the close of the SEC’s case, on May 30, 2008, Defendants moved for a judgment on partial findings pursuant to Federal Rule of Civil Procedure 52(c). Defendants argued that the SEC failed to establish a fraud committed by Defendants for which they would be primarily liable, an underlying fraud committed by Joseph, or, even assuming that Joseph committed securities fraud, that Defendants are secondarily liable for any alleged violation. Defendants underscore that the SEC did not establish any supervisory standards by which the fact-finder could gauge Defendants’ conduct. The SEC opposed the motion, contending that it proffered sufficient proofs for the Court to find in its favor. After receiving briefing on the issue and hearing extensive arguments placed on the record on June 2, 2008, the Court reserved decision on the motion. Because the Court now addresses the entirety of the action on its merits, Defendants’ motions are moot. B. Witnesses Presented at Trial The SEC proffered the following factual witness who worked for Knight during the relevant time period: Gregory Cavallo (“Cavallo”); Carmine Curra (“Curra”); Thomas Fedele (“Fedele”); David Miller (“Miller”); Anthony Mitrano (“Mitrano”); Kenneth Ackerman (“Ackerman”); Alan Levinson (“Levinson”); John Howard (“Howard”); John Hewitt (“Hewitt”); and Pasternak. Cavallo, who was a sales trader at Knight during the relevant time frame, testified on May 14 and 15, 2008. (Tr. 438:6-633:20). He averred as to the function of a sales trader at Knight, (Tr. 441:19-24), the setting and manner in which the sales traders worked, (Tr. 444:2-446:6, 448:19-449:20), and the management structure of Knight’s institutional sales desk, (Tr. 446:8-448:17, 479:1-480:6, 474:18-477:6). Specifically, Cavallo testified as to his obligations as a sales trader working an institutional not-held order and how he fulfilled those obligations. (Tr. 450:20-473:3, 545:10-549:25, 568:17-583:18, 587:10-594:4). He also stated that Knight compensated sales traders based on a percentage of the profit or loss for a particular trade — an allocation negotiated between the sales trader and the market maker for that trade. (Tr. 473:4-474:13, 524:24-528:14, 556:6-568:15, 583:19-587:8). Finally, Cavallo discussed his recollection of Joseph’s trade of Costco (COST:NASDAQ) (“COST”) shares that generated a large “profit and loss” number (“P & L”) on the computer program employed by Knight, the Brokerage Real Time Application Support System (“BRASS”). (Tr. 482:4-486:24, 528:18-535:1, 596:22-600:15, 603:12-608:9). Curra was also a sales trader at Knight during the relevant time period of 1999 to 2000. He testified on May 19 and 20, 2008. (Tr. 1002:11-1022:14, 1050:3-1069:22). Curra testified as to the general practices of a Knight sales trader in executing trades on behalf of institutional customers. (Tr. 1008:4-1021:17, 1065:8-1067:17, 1068:2-20). Notably, Curra averred that Knight’s “substantial retail order flow” could affect an order handled by a sales trader. (Tr. 1061:5-25). Curra also discussed the supervision of sales traders and compliance procedures in effect during his tenure at Knight. (Tr. 1007:20-1008:3, 1062:1-1064:2). Another testifying sales trader was Fe-dele, who testified on May 20, 2008. (Tr. 1181:20-1231:25). Similar to Cavallo and Curra, Fedele described the atmosphere of Knight’s institutional sales desk, (Tr. 1185:19-1187:2), and testified as to his obligations as a sales trader, (Tr. 1183:12-15), and how he would fulfill those obligations, (Tr. 1183:16-1185:18). He also testified as to how he received and handled institutional not-held orders, (Tr. 1191:17-1203:8, 1214:17-1221:17), and the complexity of working those orders as the market maker handled retail order flow, (Tr. 1205:8-1210:4). In addition, Fedele discussed the manner in which sales traders were supervised, including John’s role as manager of the sales desk. (Tr. 1187:3-1191:16, 1210:6-1214:15). Finally, he explained how Knight compensated its sales traders. (Tr. 1203:9-1204:15, 1223:18-1228:22, 1229:3-1230:17). To describe the manner in which sales traders in general and Joseph in particular worked an order, the SEC proffered the testimony of Miller and Mitrano, who both served as assistants to Joseph and John. The SEC provided Miller’s testimony on May 16, 2008, (Tr. 818:9-25); (Exhibit 1106), and Mitrano’s testimony on May 20, 2008, (Tr. 1173:11-15); (Exhibit 1111). Miller testified as to John’s supervision of the sales desk and interactions with his brother, Joseph. (Exhibit 1106 at 16-17, 21-24, 64-65, 68-69, 73-75, 145-48, 150-53). Miller also described the contents of an order ticket and his responsibilities as an assistant in respect of handling an institutional order. (Exhibit 1106 at 45-51, 55-59, 69-70, 72-73, 75-86, 88, 99-106, 112, 114-15, 124-45, 154-60). Miller further detailed Knight’s method for calculating a sales trader’s compensation on a particular trade. (Exhibit 1106 at 112-14, 116-19). Mitrano testified in accordance with Miller’s testimony, discussing his role as an assistant on the institutional sales desk, including how he completed order tickets, handled orders, and printed shares for Joseph. (Exhibit 1111 at 16-19, 23-33, 40-41, 44-49, 52-53, 55-57, 64, 67-68, 71-72, 75-82, 88-93). Mitrano also explained how he calculated a profit and loss calculation on a particular trade. (Exhibit 1111 at 60-63, 66-67). The SEC provided the Court with testimony from two market makers at Knight: Ackerman and Levinson. The Court heard Ackerman’s testimony on May 16, 2008. (Tr. 837:4-8); (Exhibit 1108). Ack-erman, Knight’s trading room manager and market maker, testified as to the function of a Knight market maker, the tools he used to operate, and Pasternak’s oversight of the market making desk. (Exhibit 1108 at 13-17, 26-31, 33-38, 40-45). In addition, Ackerman detailed Knight’s system of handling retail order flow and how such orders could affect the execution of an institutional order. (Exhibit 1108 at 23-25, 31-33). Finally, Ackerman averred as to his interactions with Joseph and his knowledge of Joseph’s trading practices. (Exhibit 1108 at 38-39, 47-49). Levinson, a market maker who testified on May 23, 2008, (Tr. 1650:20-1735:8), described the setting of Knight’s market making desk, (Tr. 1657:19-1658:15), including managerial supervision of the desk, (Tr. 1661:3-1664:6, 1714:4-1716:2, 1725:5-1726:12), and defined the role of a market maker, (Tr. 1658:16-1659:13). Levinson explained how a market maker would handle an institutional not-held order supplied by a sales trader, including determining the price of a stock given to the customer. (Tr. 1659:14-1661:1, 1664:19-1687:23, 1706:24-1712:5). He also described how Knight handled retail order flow and automatic executions, (Tr. 1670:1-1673:9, 1721:18-1724:9), as well as the process for calculating sales credits and determining a sales trader’s compensation, (Tr. 1716:3-1718:7). Finally, Levinson detailed his handling of a trade of E-Tek Dynamics (ETEK:NASDAQ) (“ETEK”) stock brought to him by Joseph. (Tr. 1688:23-1703:15). On May 20, 2008, the Court heard the testimony of Howard, Knight’s controller during the relevant time period of 1999-2000. (Tr. 1071:2-1144:25); (Exhibit 36 at KN 1280). Howard testified as to his responsibilities and duties as a controller, (Tr. 1072:23-1073:10), and described various documents produced by the accounting department relating to the profits generated by Knight’s sales traders, (Tr. 1073:14-1116:10, 1125:21-1138:21, 1143:9-1144:21). He also discussed how Knight calculated sales credit data for each sales trader. (Tr. 1075:23-1082:14, 1084:10-1085:8, 1117:2-1121:4, 1123:25-1124:16, 1138:23-1140:24, 1141:5-24). Howard averred that the information the accounting department used to generate its reports and the reports themselves were available to market makers, sales traders, and members of the executive committee at Knight. (Tr. 1120:3-16). The SEC proffered the testimony of Hewitt, Knight’s President and Director from mid-1999 until mid-2001, on May 21, 2008. (Tr. 1264:11-1462:3). Hewitt detailed his role at Knight as President. (Tr. 1275:2-1279:12). Specifically, Hewitt testified as to his lack of understanding in respect of how John and Joseph generated profits for Knight and his belief, based on his incomprehension, in addition to a phone call from a trader outside of Knight, (Tr. 1287:25-1288:13), that the brothers were engaged in a form of front-running. (Tr. 1279:13-1282:14). Hewitt averred that he informed Pasternak, the Board of Directors, and Knight’s general counsel of his concern, (Tr. 1282:15-1285:16, 1295:13-1296:19), and that, in response, Pasternak agreed to permit Hewitt to hire someone to replace John as head of the institutional sales desk, (Tr. 1285:20-1286:6). Hewitt further testified that he did in fact hire Robert Stellato (“Stellato”) for that position, (Tr. 1289:4-1290:1), and that one of Stellato’s assignments was to determine how Joseph executed his trades, (Tr. 1290:3-1291:13). Hewitt also detailed the events leading to the Leightons’ departure from Knight. (Tr. 1292:13-1294:16). On May 27 and 28, 2008, the Court heard testimony from Pasternak. (Tr. 1773:19-2076:21). Pasternak was the Chief Executive Officer (“CEO”), President, and Chairman of the Board of Directors of Knight Trimark Group, Knight’s parent company, during 1999 to 2000. (Tr. 1775:24-1778:6). Until some time before August 7, 2000, Pasternak also served as a supervisor of the market making desk. (Tr. 1778:19-1779:6, 1781:4-17). Pasternak described Knight’s formation and general business model. (Tr. 1980:14-1986:22). Pasternak also testified as to his duties and responsibilities at Knight, including the amount of time he spent at the market making desk and his limited role in executing institutional orders. (Tr. 1785:15-1793:3). He discussed his knowledge of Joseph’s sales credits and profits, (Tr. 1794:1-1800:1, 1805:21-1808:24, 1813:1-1814:1, 1998:21-2000:1), in addition to his review and understanding of Joseph’s trading practice, (Tr. 1800:13-1801:20, 1814:2-13, 1867:18-1870:15). Pasternak testified as to his method for spot-checking certain trades. (Tr. 1801:21-1805:20). Significantly, Pasternak averred as to Knight’s practices for generating P & L numbers, (Tr. 1806:20-1812:25, 1840:24-1841:22, 1902:13-1903:14), calculating compensation, (Tr. 1875:12-1889:10), and general trading practices, (Tr. 1829:11-1831:23, 1966:4-1968:22, 2000:2-2004:3, 2033:3-2036:7, 2053:5-2057:16, 2058:5-2061:2). In his testimony, Pasternak stated that, in 1999 and 2000, he believed that Knight’s profits caused a potential “marketing problem,” and he explained how he reacted to Hewitt’s belief that the Leightons engaged in front-running. (Tr. 1842:4-1859:24, 1861:18-1864:6, 2004:12-2008:2, 2009:23-2017:3). Pasternak recounted his efforts to determine whether Joseph’s trading practice was illegal in light of Hewitt’s concerns. (Tr. 1848:22-1867:17, 1870:16-1871:21, 1911:19-1931:3, 1963:11-1966:2, 1968:24-1977:12, 2017:5-2022:17). Finally, Pasternak described the circumstances surrounding the departure of the Leigh-tons from Knight. (Tr. 2023:5-2027:20, 2036:9-2039:1, 2047:23-2051:14). The SEC also proffered extensive testimony from Knight’s institutional customers: Andrew Brooks (“Brooks”); William Lawlor (“Lawlor”); Stuart George (“George”); Scott Thornton (“Thornton”); William Schubert (“Schubert”); Kurt Smith (“K. Smith”); Francine Smith (“F. Smith”); Margaret Mace (“Mace”); Robert Marcotte (“Marcotte”); and William Perry (“Perry”). Brooks, the Head of the U.S. Equity Trading Desk at T. Rowe Price Group, Inc. (“T. Rowe”), testified on May 13 and 14, 2008. (Tr. 45:1-298:19). He testified as to the nature of his employer’s business, how “buy-side” firms operated, and what his business expected from broker-dealers like Knight. (Tr. 49:10-104:22, 115:24-117:3, 134:13-25, 138:22-144:17, 149:1-152:21, 154:11-155:4, 165:4-169:7, 204:24-210:9, 212:12-221:14, 283:16-289:20, 290:19-295:4). Brooks also provided a foundational background to much of the terminology employed throughout the trial, as well as general information in respect of the NASDAQ market. (Tr. 66:14-67:9, 69:18-71:15, 88:1-90:13, 96:24-97:9, 99:6-18, 105:15-110:6, 130:12-134:12, 135:2-136:4, 155:5-165:2). In addition, Brooks discussed the relationship between T. Rowe and Knight in 1999 to 2000. (Tr. 104:23-105:10, 110:8-125:14, 136:14-138:21, 144:19-148:25, 169:9-181:14, 184:1-200:13, 201:10-208:21, 221:15-235:2, 269:17-283:11, 298:3-15). On May 14,'2008, Lawlor, Manager and Vice-President of Equity Trading at Davis Selected Advisors (“Davis Selected”), testified. (Tr. 301:4-383:10, 389:2-4). Lawlor described his responsibilities and obligations as manager of the trading desk at the private mutual fund company. (Tr. 301:14-304:7, 324:14-325:5). He also testified as to his understanding of how not-held orders operated and his expectations in respect of the execution of those orders. (Tr. 304:9-309:21, 313:18-314:11, 319:3-324:2, 327:24-329:24, 338:13-339:18, 359:2-363:7, 365:22-369:24, 375:21-382:23). Law-lor further enunciated the manner in which traders at Davis Selected traded in general, (Tr. 309:23-310:11, 315:20-316:19), and Davis Selected’s relationship with Knight, (Tr. 310:13-313:21, 316:20-318:17, 339:19-343:10, 346:4-351:1, 370:1-374:22). Specifically, Lawlor discussed a trade of COST shares executed by Knight. (Tr. 314:12-315:19, 326:2-327:21, 329:25-338:4, 351:2-356:10). George also testified on May 14, 2008. (Tr. 397:10-437:24). George, the Senior Vice-President of Equity Trading at Delaware Investments (“Delaware”) during the relevant time frame, testified similar to the other buy-side customers. He described the not-held order, how Delaware sought the execution of those orders, and his expectations in respect of the execution. (Tr. 399:22^05:23, 410:20-411:5, 416:19-423:18, 426:10^28:13, 429:14-430:2, 431:9-437:21). George also averred as to his interactions with, and orders executed by, Knight. (Tr. 405:24-410:13, 411:2-414:10, 414:24^16:18, 423:19-426:9, 428:14-429:12, 430:3-431:1). On May 16, 2008, the SEC proffered the testimony of Thornton, (Tr. 767:8-19); (Exhibit 1103), Schubert, (Tr. 777:8-12, 778:3-4); (Exhibit 1104), and K. Smith, (Tr. 803:17-22); (Exhibit 1105). Thornton, during the relevant time period, was Portfolio Manager and Vice-President of Dimensional Fund Advisors (“Dimensional”), one of Knight’s customers. (Exhibit 1103 at 13-14). In his testimony, Thornton described his employer’s business, including how Dimensional placed its orders. (Exhibit 1103 at 15-18, 23-32, 43-48, 52-56, 59-65, 68-73, 76, 87-93, 95-96). Schubert, Managing Director, Head of Equity Trading at Trust Company of the West (“Trust”), another Knight customer, testified similar to Thornton. (Exhibit 1104 at 17, 21). Schubert described the manner in which his company sought the execution of trades with firms like Knight and discussed his expectations in respect of those trades. (Exhibit 1104 at 35-37, 43-44, 46-47, 49-50, 75-77, 85-92, 108, 119-21, 123-27, 177-89). He also testified as to his personal trading experiences with Knight. (Exhibit 1104 at 63-65, 73-74, 78-82,117,128-29,198-99, 202-03). K. Smith, an equity trader with Fidelity Investments (“Fidelity”), testified in accordance with the other buy-side witnesses. He explained his role in executing fund managers’ trades at Fidelity, (Exhibit 1105 at 9, 11-12), and how he chose a market maker to execute his trades, (Exhibit 1105 at 22-24). K. Smith also discussed how broker-dealers in general and Knight in particular executed his orders. (Exhibit 1105 at 28-30, 32-33, 37-44, 48-54, 71-82). In his testimony, he detailed his transaction with Joseph for a trade in Synopsys, Inc. (SNPS:NASDAQ) (“SNPS”) shares on August 9, 2000. (Exhibit 1105 at 62-66, 82-90). On May 22, 2008, the SEC offered the testimony of two additional buy-side witnesses: F. Smith, (Tr. 1617:6-11); (Exhibit 1113), and Mace, (Tr. 1613:18-23); (Exhibit 1112). F. Smith, Trader and Vice-President of Trust, testified as to her trading practices in 1999 and 2000. (Exhibit 1113 at 21-22, 32, 46-53, 58-60, 64-65, 67, 69-73, 78-81, 100-02, 107-09, 117-18). She also discussed her relationship Joseph and Knight. (Exhibit 1113 at 81-82, SO-SO, 106-07, 109-10). Between 1999 and 2000, Mace was Head Trader at Pilgrim Baxter and Associates, Ltd. (“Pilgrim”). (Exhibit 1112 at 47). Mace testified in accordance with the other institutional customers, detailing her trading methodology and experiences with Knight. (Exhibit 1112 at 29-30, 36-38, 40-43, 51-52, 54-57, 72-73, 75-76, 83-84, 115-17, 127-28, 185-87,190-91,193-99, 210-14). The Court also heard testimony from Marcotte, (Tr. 2285:18-22); (Exhibit 1117), on May 29, 2008, and Perry, (Tr. 2294:8-17; 2424:6); (Exhibit 1119), on May 30, 2008. Marcotte, an equity trader at T. Rowe, testified as to his trading practices and expectations from a broker-dealer executing his trades. (Exhibit 1117 at 30, 32-33, 36-37, 42-45, 52-66, 90-92, 94). He also provided testimony as to his transactions with Knight. (Exhibit 1117 at 51-52, 69-75, 85-86, 88, 92-93, 97-98, 102-07). Perry was a trader at Putnam Investments (“Putnam”) in 1999 and 2000. (Exhibit 1119 at (1/17/2006) 56). In his testimony, Perry explained the manner in which he traded on behalf of Putnam’s customers, (Exhibit 1119 at (1/17/2006) 122, 128, 131-32, 134-35, 137-38, 195-96, 203, 213-16, 237-42, 248-52, 257-69, 272, 276-81, (1/19/2006) 6-8, 12-13, 15-16, 21-24, 26-27, 29-32, 135-36, 139, 143-44, ISO-52), and discussed his trading with Knight, (Exhibit 1119 at (1/17/2006) 82, 102, 118-19, 125-26, 208, 210, 216-19, 231-37, 245-47, 252). Specifically, he detailed his June 30, 2000 order with Knight to sell shares in Juniper Networks, Inc. (JNPR:NASDAQ) (“JNPR”). (Exhibit 1119 at (1/19/2006) 47-65, 69-95); (Exhibit 244); (Am. Cmplt. ¶ 53f). Perry also described his buy order with Knight in Efficient Networks (EFNT:NASDAQ) (“EFNT”) shares, (Exhibit 1119 at (1/19/2006) at 98); (Exhibit 395), and his order with Knight in ETEK shares on March 16, 2000, (Exhibit 1119 at (1/1/9/2006) at 98-99); (Exhibit 391); (Am. Cmpltlffl 31-32). The SEC also proffered a summary witness, Stephen P. Glascoe (“Glascoe”), to introduce into evidence certain calculations. The Court heard his testimony on May 20, 2008. (Tr. 1145:23-1171:18); (Exhibits 531-39). Glascoe is a market surveillance specialist in the SEC’s enforcement division. (Tr. 1146:1-9). He generated spreadsheets listing Joseph’s sales credit data for 1999 and 2000, as collected from Knight’s records, and his calculations of Joseph’s sales credit per share. (Exhibits 531-33). Glascoe then sorted the information by customer, date, and amount. Exhibits 534, 535, and 536 set forth Glascoe’s percentage calculations of Joseph’s “payout from trades where the payout” per share equaled $0.25 or more, $0.50 or more, and $1.00 or more, respectively. (Exhibits 534-36). In Exhibit 537, Glascoe calculated Joseph’s “profits in millions of dollars, by quarter for 1999 and 2000[.]” (Exhibit 537). In Exhibit 538, Glascoe calculated, for the period of 1999-2000, the “Percentage of Institutional Department] profits [and] share volume attributable to Joseph[.]” (Exhibit 538). Finally, in Exhibit 539, Glascoe compared Joseph’s average profit per share with those of all other traders in Knight’s institutional group for the period of 1999-2000. (Tr. 1158:5-12); (Exhibit 539). On May 15 and 19, 2008, the Court heard testimony from the SEC’s expert witness, James Cangiano (“Cangiano”). (Tr. 637:2-720:24, 865:5-1001:23). The SEC proffered Cangiano as an expert in the NASDAQ market and trading regulation, (Tr. 653:5-6), and the Court accepted Cangiano as an expert that field, (Tr. 670:6-20). Cangiano described the NASDAQ market during the time frame of 1999-2000, (Tr. 670:23-672:10), and the function and obligations of a market maker, including the handling of not-held orders and supervisory obligations, (Tr. 671:24-684:18, 712:13-718:20, 943:12-956:14, 966:8-974:16, 995:13-999:9). He also explained NASD-imposed regulations on market makers, such as the “best execution” requirement. (Tr. 684:22-720:20, 883:11-910:12, 956:15-964:19). In addition, Cangiano expressed his opinion as to Defendants’ conduct, assuming the facts alleged in the SEC’s Amended Complaint. (Tr. 872:11-878:10, 880:18-883:10, 910:24-925:24, 928:24-941:24, 964:21-966:7, 975:5-978:17, 982:9-25, 986:21-995:12). On May 22, 2008, the SEC sought to admit the testimony of Richard Gunter (“Gunter”) as an expert in the field of “market making and institutional trading” to explain standards and customs and to reconstruct Joseph’s trades. (Tr. 1497:23-1596:4-5). However, exercising its gate-keeping function, the Court found that Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), precluded the admission of Gunter’s testimony. (Tr. 1606:6-1611:11); S.E.C. v. Pasternak, 05-3905, Opinion (D.N.J. May 23, 2008). Nevertheless, the Court briefly sets forth here the substance of Gunter’s expert report. The Court notes that, had the Court admitted his expert testimony and had he testified in accordance with his report, Gunter would have reiterated much of the background information already provided via Cangiano’s testimony. Furthermore, Gun-ter acknowledged that, although he “analyzed” Knight’s data, that trade run data “speaks for itself.” (Tr. 1561:16-18). Gunter would have averred as to his review of seven trades executed by Knight. Based on his review of the “trade runs,” Gunter concluded, in his report, that Joseph engaged in front-running, or interpositioning, whereby he would manipulate the printing of shares to a customer, either delaying the print or printing using a modifier that indicated that the execution to the customer occurred at an earlier point in time. Thereby, according to Gunter, Joseph was able to conceal his profits on the transaction. Furthermore, Gunter would have testified that Defendants must have known, or were reckless in not knowing, of Joseph’s trading practices. Finally, on May 28 and 29, 2008, the SEC offered the expert testimony of Daniel Levy, Ph.D. (“Dr. Levy”), an expert in the “analysis of markets and profit calculations and computing.” (Tr. 2101:6-2131:20, 2175:22-2284:23). On May 30, 2008, the Court accepted Dr. Levy’s expert testimony. (Tr. 2433:25-2435:13). Dr. Levy testified as to his creation of “a program [used] to describe the trading patterns and the profits on a set of trades ... from Knight[.]” (Tr. 2106:18-20). He described the method used to create that program, which included an allocating of shares to Knight’s inventory for the purpose of executing an institutional order. (Tr. 2118:1-2130:2, 2176:4-2182:13, 2184:9-2194:3). Dr. Levy stated that the essence of his report was to calculate Joseph’s profit on forty-six trades by subtracting the average price at which the shares were purchased from the price at which the shares were sold, for each trade. (Tr. 2183:9-2184:8). In their case-in-chief, on May 30, 2008, Defendants offered the testimony of one witness: Leonard Amoruso (“Amoruso”). (Tr. 2322:17-2423:15). Amoruso joined Knight in October 1999, as the chief compliance officer. (Tr. 2326:12-21). Amoru-so testified as to the role of a compliance department generally, and of Knight’s compliance department specifically. (Tr. 2328:5-2330:12, 2332:21-2343:4, 2367:3-2382:21, 2390:24-2392:19). He also discussed how he fulfilled his obligations as chief compliance officer. (Tr. 2330:13-2332:19, 2343:5-22, 2359:10-2366:3). Amo-ruso averred as to his understanding of rules and regulations regarding the execution of, and profits earned on, not-held orders. (Tr. 2344:21-2348:18, 2382:22-2390:23, 2418:1-2420:8). In addition, Amo-ruso explained Pasternak’s support of the compliance department. (Tr. 2344:8-20). Amoruso further detailed the steps taken after Stellato and Hewitt raised concerns in respect of Joseph’s trading practices, which included a review of three trades of SNPS, JNPR, and TUTS shares executed by Joseph. (Tr. 2350:1-2359:1, 2392:20-2417:20, 2420:14-2423:10). C. Credibility Determinations Having had the opportunity to discern the demeanor of the witnesses, to hear their testimonies, and to review extensively the transcripts of the trial, the Court finds the testimony of all fact witnesses, in addition to the summary witness Glascoe, to be credible. Indeed, all witnesses appear to have testified truthfully and to the best of their recollections. The Court underscores that it finds Pasternak’s testimony to be credible. His testimony was corroborated by all witnesses and rebutted only by the SEC’s conclusory allegations. Indeed, Pasternak’s testimony before the Court was his fifth opportunity in which he could attest to the facts giving rise to the action. Although the SEC attempted to impeach Pasternak with his previous sworn testimony, the Court finds that no material inconsistencies exist between Pasternak’s statements. Moreover, the Court rejects the SEC’s argument that Pasternak’s statement that he believed Joseph’s trading caused a “marketing problem” is an admission that Pasternak had actual knowledge that Joseph engaged in fraudulent conduct. Rather, the Court finds this statement as establishing that Knight’s profitability and success in a volatile period generated “envy” among its corporate peers and had the potential to cause a perception that Knight, and Joseph, engaged in improper or sharp business practices. Such a belief and perception are corroborated by the testimony of Levinson and Brooks, who averred, respectively, that Knight was in “bubble” that caused it to be subject to stricter scrutiny and that Knight’s peers envied and scrutinized Knight because of its profitability. (Tr. 170:2-7, 1725:8-1726:12). In respect of the expert testimony, the Court finds the testimony of Cangiano credible. The Court, however, reiterates its finding reached during the trial that Gunter could not properly testify as an expert in the field of “market making and institutional trading” for the purpose of explaining standards and customs or reconstructing Joseph’s trades. Moreover, in respect of Dr. Levy’s testimony and proffered exhibits, the Court grants Dr. Levy’s calculations and analysis limited weight. Specifically, the Court finds that Dr. Levy’s allocation of shares to Knight’s inventory for the purpose of executing a particular institutional order, rather than for the purpose of executing retail orders — labeled in Dr. Levy’s documents as “current order inventory,” (Tr. 2186:15-22) — -is undermined by Dr. Levy’s reliance on Gunter for that process. (Tr. 2218:21-2219:16). In reviewing Knight’s trading data, to separate “intervening” trades caused by Knight’s retail order flow, Dr. Levy allocated shares acquired or sold by Knight’s market maker immediately after receipt of an intervening trade to retail order flow and segregated any profit derived therefrom. (Tr. 2187:19-2188:20). However, Pasternak explained that it is “very difficult or virtually impossible” to determine “where the participation of the institution occurred in this continuum of low volume and price movements with all this retail interaction.” (Tr. 1809:23-1810:3, 1811:4-18). In addition, Amoruso testified that, based on a review of Knight’s trading records, it would be difficult to determine whether certain shares acquired or sold after receipt of an institutional order was actually allocated to that institutional order. (Tr. 2401:18-2402:11). For example, Amoruso specified that the accumulation of stock could be due to Knight’s “buying from retail sell orders ..., as opposed to actually going out in the market and buying stock on behalf of that institutional order[.]” (Tr. 2402:2-6, 2405:13-2406:7). Ackerman, one of Knight’s market makers, further explained that retail order flow would execute automatically to a certain point, but after reaching a threshold volume, the retail orders would enter a queue from which a market maker must manually execute the orders. (Exhibit 1108 at 31-33). Furthermore, Mitrano, who, as Joseph’s assistant, would review trade runs on a daily basis to determine a profit and loss calculation, testified it was “extremely difficult” to distinguish between retail and institutional orders. (Exhibit 1111 at 61:22-62:16). In fact, Mitrano averred that there was no visual distinction between the two types of orders on the trade run data extracted from BRASS. Thus, four witnesses with experience reviewing Knight trade data testified that (1) it is almost impossible to allocate shares between institutional orders and retail orders, (2) Knight’s acquisition of a position of shares after receipt of an institutional order is not necessarily in response to an institutional order, but could be the result of executions for retail orders, and (3) not all retail orders would be executed immediately upon receipt of the order. Importantly, Pasternak, Amoruso, Ack-erman, and Mitrano had experience in handling voluminous retail order flow and reviewing trade run data reflecting such order flow. In contrast, Gunter admittedly had no experience in handling any retail order flow, distinguishing retail order flow from institutional orders on a trade run, or determining how that order flow could affect executions of institutional orders. As a result, the Court finds Pasternak, Amo-ruso, Ackerman, and Mitrano more credible than Gunter in their ascertainment of the difficulty in allocating shares between retail orders and institutional orders. Because the testimony of Pasternak, Amoru-so, Ackerman, and Mitrano contradict Gunter’s analysis of separating out retail order flow from Knight’s trade run data, the Court finds Dr. Levy’s reliance on Gunter for allocation of shares to determine an institutional order’s inventory of shares undermines his ultimate calculation of the profitability of Joseph’s trades. II. STATUTORY AND REGULATORY BACKGROUND The Court must consider this case against the backdrop of the complex and intricate statutory and regulatory body of law applicable to the securities industry. For that reason, the Court sets forth at the outset the relevant statutes and regulations. In addition, the Court details the rules and notices promulgated by the National Association of Securities Dealers, Inc. (“NASD”) implicated by the SEC’s allegations. A. Applicable Statutes under the Securities Act and the Exchange Act The SEC’s Amended Complaint seeks to impose primary and secondary liability for alleged violations of the following statutes and regulations: Section 17(a) of the Securities Act, 15 U.S.C. § 77q(a); Sections 10(b), 15(c)(1)(A), and 17(a) of the Exchange Act, 15 U.S.C. §§ 78j(b), 78o(c)(l)(A), and 78q(a)(l); and Rules 10b-5 and 17a-3, 17 C.F.R. §§ 240.10b-5 and 240.17a-3(a). Those statutes and regulations fall into two categories: first, statutes and regulations prohibiting fraudulent conduct — Securities Act Section 17(a), Exchange Act Sections 10(b) and 15(c)(1)(A), and Rule 10b — 5; and, second, the statute and regulation governing record-keeping by broker-dealer firms — Exchange Act Section 17(a) and Rule 17a-3. Securities Act Section 17(a), Exchange Act Sections 10(b) and 15(c)(1)(A) and Rule 10b-5 all proscribe fraudulent conduct in connection with the purchase and/or sale of securities. Section 17(a) provides that [i]t shall be unlawful for any person in the ... sale of any securities ... by the use of any means or instruments of transportation or communication in interstate commerce or by use of the mails, directly or indirectly (1) to employ any device, scheme, or artifice to defraud[;] or (2) to obtain money or property by means of any untrue statement of a material fact or any omission to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading; or (3)to engage in any transaction, practice, or course of business which operates or would operate as a fraud or deceit upon the purchaser. 15 U.S.C. § 77q(a). Similarly, Section 10(b) of the Exchange Act prohibits the use of mails or instruments of interstate commerce or “of any facility of any national securities exchange” for employing, in connection with the purchase or sale of any security, “any manipulative or deceptive device or contrivance in contravention of such rules and regulations as the [SEC] may prescribe as necessary or appropriate[.]” 15 U.S.C. § 78j(b). Rule 10b-5, promulgated under Section 10(b) of the Exchange Act, also prohibits the use of mails or instruments of interstate commerce or “of any facility of any national securities exchange”: (a) To employ any device, scheme, or artifice to defraud, (b) To make any untrue statement of a material fact or to omit to state a material fact necessary in order to make the statements made, in the fight of the circumstances under which they were made, not misleading, or (c) To engage in any act, practice, or course of business which operates or would operate as a fraud or deceit upon any person in connection with the purchase or sale of any security. 17 C.F.R. § 240.10b-5. Section 10(b) and Rule 10b-5 aim “to prevent rigging of the market and to permit operation of the natural law of supply and demand[,]” resulting in a market price that “reflects as nearly as possible a just price.” S.E.C. v. First Jersey Sec., Inc., 101 F.3d 1450, 1466 (2d Cir.1996) (internal quotation marks omitted). Finally, Section 15(c)(1)(A) of the Exchange Act states that “[n]o broker or dealer shall make use of the mails or any means or instrumentality of interstate commerce to effect any transaction in, or to induce or attempt to induce the purchase or sale of, any security ..., by means of any manipulative, deceptive, or other fraudulent device or contrivance.” 15 U.S.C. § 780(c)(1)(A). The SEC also seeks to impose secondary liability on Defendants for alleged violations of Section 17(a)(1) of the Exchange Act and Rule 17a-3. Section 17(a)(1) of the Exchange Act requires registered broker-dealers to maintain certain records. 15 U.S.C. § 78q(a)(l). Rule 17a-3 lists the books and records that must be maintained. 17 C.F.R. § 240.17a-3(a). Those records include blotters and ledgers providing data on a broker-dealer’s daily trading activity. 17 C.F.R. § 240.17a-3(a). Although there may be limitations to a civil cause of action brought under Section 17(a) of the Exchange Act, the Court need not address here whether those limitations preclude the SEC’s claim against Defendants in this instance; indeed, neither party presented the issue to the Court. See Touche Ross & Co. v. Redington, 442 U.S. 560, 569-571, 99 S.Ct. 2479, 61 L.Ed.2d 82 (1979). In addition to seeking primary liability for Defendants’ alleged violations of Section 17(a) of the Securities Act, the SEC invokes Sections 20(e) and (a) to impose secondary liability for underlying violations of Sections 10(b), 15(c)(1)(A), and 17(a) of the Exchange Act, as well as Rules 10b-5 and 17a-3. 15 U.S.C. § 78t(a), (e). Section 20(e) governs aiding and abetting persons, while Section 20(a) governs controlling persons. The SEC claims that Defendants aided and abetted Joseph’s violations of the Exchange Act. Section 20(e) of the Exchange Act imposes liability upon those persons who aid and abet violations of the Act. 15 U.S.C. § 78t(e). That statute provides that any person that knowingly provides substantial assistance to another person in violation of a provision of this chapter, or of any rule or regulation issued under this chapter, shall be deemed to be in violation of such provision to the same extent as the person to whom such assistance is provided. Ibid. The SEC also alleges that Pasternak is liable for the violations of Exchange Act Sections 15(c)(1)(A) and 17(a) and Rule 17a-3 committed by John, Joseph, and Knight. Section 20(a) imposes joint and several liability on “control persons.” That statute provides: Every person who, directly or indirectly, controls any person liable under any provision of this chapter or of any rule or regulation thereunder shall also be liable jointly and severally with and to the same extent as such controlled person to any person to whom such controlled person is liable, unless the controlling person acted in good faith and did not directly or indirectly induce the act or acts constituting the violation or cause of action. 15 U.S.C. § 78t(a). The purpose of this provision is “to impose liability on persons who were able to directly or indirectly exert influence on the policy and decision-making process of others.” Rochez Bros., Inc. v. Rhoades, 527 F.2d 880, 884 (3d Cir.1975). B. Applicable NASD Regulations The NASDAQ is a self-regulating market owned and regulated by the NASD. Newton v. Merrill Lynch, Pierce, Fenner & Smith, Inc., 259 F.3d 154, 169 (3d Cir.2001). The SEC exercises oversight authority over the NASD. Ibid.; 15 U.S.C. §§ 78f, 78o-3, 78s. To regulate the market and its members, the NASD promulgates rules, policies, and guidelines. Hoxworth v. Blinder, Robinson & Co., 980 F.2d 912, 914 (3d Cir.1992). The present case necessarily implicates some of those rules and regulations in effect in 1999 and 2000. On all trading, the NASD requires “best execution.” NASD Rule 2320; (Exhibit 89). Subsection (a) of Rule 2320 states: In any transaction for or with a customer or a customer of another broker-dealer, a member and person associated with a member shall use reasonable diligence to ascertain the best market for the subject security and buy or sell in such market so that the resultant price to the customer is as favorable as possible under prevailing market conditions. Among the factors that will be considered in determining whether a member has used “reasonable diligence” are: (1) the character of the market for the security, e.g., price, volatility, relative liquidity, and pressure on available communications; (2) the size and type of transaction; (3) the number of markets checked; (4) accessibility of the quotation; and (5) the terms and conditions of the order which result in the transaction, as communicated to the member and persons associated with the member. NASD Rule 2320(a); (Exhibit 89). Subsection (f) of that Rule further explains that the best execution obligation applies “where the member acts as agent for the account of his customer” and “where retail transactions are executed as principal and contemporaneously offset.” NASD Rule 2320(f); (Exhibit 89). However, “[s]uch obligations do not relate to the reasonableness of commission rates, markups or markdowns which are governed by Rule 2440 and IM-2440.” NASD Rule 2320(f); (Exhibit 89). To further explain Rule 2320, the NASD issued Interpretive Memo (“IM”) 2320, entitled “Interpretive Guidance with Respect to Best Execution Requirements.” IM-2320; (Exhibit 89). To also explain Rule 2320, the NASD issued Notice to Members (“NTM”) 97-57 in 1997, providing guidance on SEC order handling rules, NASD limit order protection rules, and best execution responsibilities. NTM 97-57 (Sept.1997); (Exhibit 84). NTM 97-57 explains that “the application of best execution concepts necessarily involves a ‘facts and circumstances’ analysis! ]” and that the best execution obligation “evolves as rules and systems change.” NTM 97-57 (Sept.1997); (Exhibit 84 at 457, “Questions and Answers”). In addition, this NTM specifically discusses how a market maker meets the best execution requirement when handling a discretionary, not-held order. NTM 97-57 (Sept.1997); (Exhibit 84 at 460, “Answer 8”). The NASD also regulates prices and commissions where a market maker buys or sells for its own account from or to its customer. NASD Rule 2440; (Exhibit 944). Rule 2440 provides that, in those instances, a broker-dealer shall buy or sell at a price which is fair, taking into consideration all relevant circumstances, including market conditions with respect to such security at the time of the transaction, the expense involved, and the fact that he is entitled to a profit; and if he acts as agent for his customer in any such transaction, he shall not charge his customer more than a fair commission or service charge, taking into consideration all relevant circumstances, including market conditions with respect to such security at the time of the transaction, the expense of executing the order[,] and the value of any service he may have rendered by reason of his experience in and knowledge of such security and the market therefor. NASD Rule 2440; (Exhibit 944). To further ensure fair dealing with customers, the NASD implemented a “5% Policy” applicable to commissions, markups, and markdowns. NTM 93-81 (1993). Pursuant to that policy, the NASD warns that “it may be conduct inconsistent with just and equitable principles of trade for a member to charge a commission that is not reasonable.” NTM 93-81 (1993). Fairness and reasonableness of a commission or markup “is determined by considering all relevant factors to the transaction!,] including market conditions with respect to such security at the time of the transaction, the expense of executing the order!,] and the value of any service he may have rendered by reason of his experience in and knowledge of such security and the market therefore.” NTM 93-81 (1993). To establish a general guide for determining fairness and reasonableness, the NASD finds that a commission or markup should not generally exceed five percent of the total transaction amount, “unless the member can show or document factors under the policy that justify a higher amount.” NTM 93-81 (1993). Essentially, “the percentage of commission on the transaction is only one ” relevant factor to determine if a commission is fair. NTM 93-81 (1993) (emphasis supplied). In terms of reporting requirements, the NASD explained a then-recent rule change to reporting riskless principal transactions in NTM 99-65. NTM 99-65 (August 1999); (Exhibit 85). Essentially, the new rule, effective September 30, 1999, permitted market makers to report certain transactions once, rather than twice, where it executes a trade at the same price as the order. NTM 99-65 (August 1999); (Exhibit 85 at 429, “General Questions” 1 & 3). Significantly, neither the new rule nor any other rule prevented market makers “from accumulating a position at one price and executing the offsetting trade with the customer at another price (with no markup, markdown, commission equivalent, or other fee)[J” NTM 99-65 (August 1999); (Exhibit 85 at 430, “General Questions” 6). NASD Rule 2110 requires “high standards of commercial honor and just and equitable principles of trade.” IM-2110-2; (Exhibit 1109). Based on this Rule, the NASD maintains a policy prohibiting “front running,” as expressed in IM-2110-3, as well as “trading ahead” on limit orders, as set forth in IM-2110-2. IM-2110-3; (Exhibit 1024); IM-2110-2; (Exhibit 1109). IM-2110-3 provides: It shall be considered conduct inconsistent with just and equitable principles of trade for a member or person associated with a member, for an account in which such member or person associated with a member has an interest, for an account with respect to which such member or person associated with a member exercises investment discretion, or for certain customer accounts, to cause to be executed: (a) an order to buy or sell an option or a security future when such member or person associated with a member causing such order to be executed has material, non-public market information concerning an imminent block transaction in the underlying security, or when a customer has been provided such material, non-public market information by the member or any person associated with a member; or (b) an order to buy or sell an underlying security when such member or person associated with a member causing such order to be executed has material, nonpublic market information concerning an imminent block transaction in an option or a security future overlying that security, or when a customer has been provided such material, non-public market information by the member or any person associated with a member; prior to the time information concerning the block transaction has been made publicly available. IM-2110-3; (Exhibit 1024). Similarly, IM-2110-2 explains that, based on Rules 2110 and 2320, a member cannot “trade ahead” of customer limit orders. This policy states that NASD “members that handle customer limit orders, whether received from their own customers or from another member, are prohibited from trading at prices equal or superior to that of the limit order without executing the limit order.” IM-2110-2; (Exhibit 1109). As a result, the NASD requires its members to handle limit orders with all due care so that members do not trade ahead of customer limit orders. IM-2110-2; (Exhibit 1109). III. FINDINGS OF FACT Having summarized the testimony presented, accorded weight as deemed appropriate, and set the legal and regulatory lens through which the Court must analyze the facts presented, the Court now sets forth its findings of fact. The Court notes that it rejects the proposed findings of fact submitted on numerous occasions by the SEC. Rather, the Court finds that a preponderance of the evidence submitted supports the facts proposed by Defendants. A. Background of the NASDAQ Market in 1999-2000 and Formation of Knight Securities The presently complained-of trades executed by Joseph occurred in the NASDAQ stock exchange, an over-the-counter securities market. (Am. CmpltJ 13); (Tr. 56:5-10). The NASDAQ market operates through multiple market-making firms. (Tr. 671:16-17). Essentially, a market maker serves as a broker-dealer to execute sell and buy orders for traded stocks on behalf of its customers. (Tr. 1658:16-1659:13). In so doing, the NASD requires market makers to buy or sell on behalf of a customer “at a price that is fair, taking into consideration all relevant circumstances[.]” NASD Rule 2440; (Exhibit 944). Thus, a market maker must find the best price of a particular stock, whether the best priced stock is from the market making firm’s own inventory of stock or from another source. (Tr. 1659:3-13). The best price depends on whether the order is to buy or to sell: the best offer price is the cheapest price at which one could buy a stock, whereas the best bid price is the highest price at which one could sell a stock. (Tr. 1659:14-20). To find the best price, the market maker must consider the market conditions for the particular security, the expense of the transaction, and the market maker’s entitlement to a profit. NASD Rule 2440; (Exhibit 944); (Tr. 891:12-893:25). To ascertain if a price is “fair and reasonable,” one must compare that price with other prices in the marketplace, (Tr. 713:2-715:5), and conduct a trade-by-trade “facts and circumstances analysis[,]” (Tr. 893:10-25). As part of their business, and to maintain an orderly market, these firms must necessarily commit their own capital, (Tr. 671:21-23), particularly in instances where the firm’s inventory of stock provides the best offer or bid prices, (Tr. 1659:21-1660:23). As a result, market making firms compete against each other by publicizing quotes on a particular stock in their inventory to attract order flow and volume. (Tr. 671:16-20,1659:21-1660:4). In carrying out its business, a market making firm handles different types of orders. (Tr. 672:11-674:5). One type is the “market order,” which a market maker must execute “instantaneously against the best quoted market.” (Tr. 672:15-22). The purpose of a market order is immediate best execution. (Tr. 673:10-11). Another type of order is the “limit order,” where the customer specifically instructs the market maker to execute a trade when the stock reaches a particular price. (Tr. 672:23-673:1). The focus of a limit order is the price. (Tr. 673:11-12). A market maker also executes “not-held orders.” (Tr. 673:2-677:16). A customer placing a not-held order provides the market maker with the volume of a particular stock sought to be bought or sold and grants the market maker discretion as to price and time of execution of that trade, with the goal of achieving “best execution.” (Tr. 673:2-9). On a not-held order, a market maker is not “held” to the immediacy and price requirements imposed in a market or limit order. (Tr. 673:2-16). The NASD has defined a not-held, or “working,” order as “an order voluntarily categorized by the customer as permitting the member to trade at any price without being required to execute the customer order.” NTM 97-57 (Sept.1997); (Exhibit 84 at 460, “Answer 8”). When handling such an order, a broker-dealer “must use its brokerage judgment in the execution of the order, and if such judgment is properly exercised, the broker is relieved of its normal responsibilities with respect to the time of execution and the price or prices of execution of such an order.” NTM 97-57 (Sept.1997); (Exhibit 84 at 460, “Answer 8”). Although the customer bestows discretion to the broker-dealer, a customer nevertheless monitors the transaction and modifies the parameters of the order as it deems necessary. (Tr. 975:13-976:15). In the NASDAQ market, a trade in stock can be either on a principal or agency basis. (Tr. 917:18-918:20). The NASD defines a principal trade as “a trade in which the broker-dealer buys or sells for an account in which the broker-dealer has a beneficial ownership interestf,]” such as a proprietary account. (Tr. 917:24-918:9). In contrast, an agency trade is “a trade in which a broker-dealer ... acts as an independent intermediary for the account of its customer[]” and does not execute orders in a proprietary account. (Tr. 918:10-20). An agency trade is generally considered to be a riskless transaction for the broker-dealer. (Tr. 678:1-14). A principal trade may also be riskless. (Tr. 678:1-22, 918:25-919:12). The NASD defines a riskless principal trade as a trade “in which a broker-dealer, after having received an order to buy [or] sell a security, purchases [or] sells a security as prin-eip[al] at the same price ... to satisfy that order.” (Tr. 919:2-12); NTM 99-65 (Aug. 1999); (Exhibit 85 at 429, “General Questions” 3). On a riskless principal trade, the broker-dealer charges its customer a disclosed mark-up, mark-down, or commission. (Tr. 678:15-22, 919:2-12). Most market makers executing institutional orders between the years 1999 to 2000, executed net trades, “accumulating shares at one price and executing to customers at a different price.” (SEC Stipulated Facts, Final Pretrial Order 1/02/2008 (“SEC Stip.”) at 17 ¶ 48); (John Stipulated Facts, Final Pretrial Order 1/02/2008 (“John Stip.”) at 5 ¶ 16); (Tr. 678:19-679:5, 919:16-920:4). The NASD defines a net trade as one in which “a market maker, at the request of a customer[,] while holding a customer order[] to buy [or] sell executes a buy [or] sell as principal] at one price from the street or another customer and then executes an offsetting sell [or] buy from the customer at a different price.” (Tr. 919:18-22); (John Stip. at 5 ¶ 17); NTM 97-5
