The Securities and Exchange Commission (SEC or Commission) on May 1, 2014 announced a settlement (Settlement) with the New York Stock Exchange LLC and certain of its affiliates (collectively, the NYSE), addressing a variety of practices – including informational disparities and the current hot-button topic of co-location.1 In this latest settlement concerning electronic trading and the dissemination of market data,2 the NYSE agreed, without admitting or denying the SEC’s findings, to settle charges relating to a wide variety of historic conduct that largely took place between 2005 and 2011. As part of the Settlement, the NYSE consented to a $4.5 million civil monetary penalty and the retention of a compliance consultant.

The Settlement marks the first enforcement action by the SEC implicating practices employed by electronic and high-frequency trading (HFT) firms since the publication of Michael Lewis’ book, “Flash Boys” – in which Mr. Lewis argues that HFT unfairly exploits informational disparities. The Settlement also follows criticism by the New York Attorney General (NYAG) of co-location arrangements at securities exchanges, as well as calls by the NYAG for the SEC and other regulators to focus their attention on HFT issues.3

This OnPoint discusses the three charges in the Commission’s order that specifically address informational disparities, namely: (1) the provision of co-location services to certain customers prior to September 2010, pursuant to terms that were individually negotiated with private firms and not submitted for SEC approval; (2) the lack of procedures to prevent the misuse of non-displayed liquidity in order books for exchange error account trading; and (3) the early distribution of order imbalance information to floor brokers – a practice that was not fully disclosed to the public.4 The OnPoint also explores how the Settlement is consistent with prior statements and practices by the SEC staff concerning market structure issues.

Description of the Settlement

Allegations that Prior to September 2010, NYSE Provided Co-Location Services without SEC Approval

“Co-location” is a service offered by securities exchanges that enables market participants to obtain faster access to exchange information, often by permitting trading firms to place servers at exchanges’ data centers in order to have direct access to trading data. Although a market center is not permitted to provide data to private linkages prior to the time that such data is reported to the securities information processor (SIP) for public dissemination, direct data feeds allow firms to receive and act on information microseconds prior to the time the information is published by the public data feed.

Previously, in its 2010 concept release on equity market structure, the SEC acknowledged the role of co-location at registered exchanges:

The Commission believes that the co-location services offered by registered exchanges are subject to the Exchange Act. Exchanges that intend to offer co-location services must file proposed rule changes and receive approval of such rule changes in advance of offering the services to customers. The terms of co-location services must not be unfairly discriminatory, and the fees must be equitably allocated and reasonable.5

Despite the criticism of co-location by Michael Lewis and the NYAG, the Settlement confirms that the Commission has approved, and now regulates, the provision of co-location services as “a material aspect of the operation of the facilities of a national securities exchange.” In the Settlement, however, the SEC focused upon the contention that, from at least 2006 through September 2010, the NYSE offered co-location services without filing a proposed rule with the Commission and that, during this time period, the fees charged by the NYSE for these services were individually negotiated and not uniform for all customers. While, in response to a recommendation by the SEC’s Office of Compliance Inspections and Examinations (OCIE), the NYSE and certain affiliates submitted rule proposals to the SEC in 2009 governing co-location services, the Commission staff expressed concerns that the proposed rule would allow for pricing disparities between new co-location customers (who would be subject to a standard rate) and old co-location customers (who would be charged their lower previously negotiated rates).

Under Exchange Act Section 6(b)(5), the rules of an exchange may not be designed to permit, among other things, unfair discrimination among customers, issuers, brokers or dealers. The SEC staff was specifically concerned that individually negotiated co-location fees could lead to questions as to whether the fees were being equitably allocated among customers. However, it was not until September 2010 that the NYSE effectuated an exchange rule that standardized co-location fees for all customers.6

According to the SEC, the NYSE’s co-location practices until September 2010 violated Section 19(b)(1) of the Exchange Act, which requires that securities exchanges file proposed rule changes with the SEC. The Settlement acknowledges that, in the initial years following the adoption of Regulation NMS, some firms may have had individually negotiated co-location agreements – a practice that is criticized in Flash Boys. At the same time, however, the Commission has underscored the fact that this is no longer tolerated and that policy issues, like co-location, have been on the SEC’s radar and subject to regulation by the Commission for the past several years.

Allegations that ArcaSec Failed to Implement Policies and Procedures to Prevent the Misuse of Material Non-Public Information in Connection with its Error Account

The SEC noted that ArcaSec, which served as a routing broker for various NYSE affiliates since 2005, used an error account to unwind securities positions that the NYSE held as a result of “computer system malfunctions or outages, unmatched orders, errors from routing to other exchanges, or accommodations.” The ArcaSec error account was traded by members of the Arca Trade Operations Desk (TOD).

The SEC alleged that, between 2005 and October 2010, TOD employees could run both their normal trading program and a separate Global Trade Manager (GTM) program that showed the NYSE’s “entire depth of book, including non-displayed liquidity.” According to the SEC, this permitted the traders to “view all non-displayed buy and sell orders for each listed security,” enabling “them to anticipate possible shifts in a security’s price from pending non-displayed orders.”

The SEC claimed that the GTM data, which was supposed to be used solely for tracking orders and facilitating efficient trading, constituted material non-public information and that, prior to October 2010, ArcaSec lacked policies and procedures to ensure that TOD employees were not using the GTM data in connection with error account trading. While the SEC notified ArcaSec of this deficiency in February 2010, the SEC alleged that ArcaSec did not sufficiently address this issue until October 2010.7

The SEC concluded that this conduct violated Section 15(g) of the Exchange Act, which requires broker-dealers to establish and implement policies and procedures to prevent the misuse of material non-public information. Specifically, the SEC found that ArcaSec: had no written policies or procedures specifically addressing the access to non-displayed liquidity information by TOD personnel liquidating securities positions in the ArcaSec error account; lacked systems that would have prevented TOD personnel from accessing such information; and lacked policies or procedures for surveilling whether the TOD personnel acting on its behalf were accessing material non-public information while trading in the error account.

The SEC noted that “the mere establishment of policies and procedures alone is not sufficient to prevent the misuse of material non-public information. It also is necessary to implement measures to monitor compliance with and enforcement of those policies and procedures.” The action by the SEC in this regard emphasizes the fact that markets must have and effectively implement procedures to prevent the misuse of customer order information.8

Allegations that NYSE Distributed Closing Order Imbalance Information in Violation of Exchange Rules

Another violation addressed in the Settlement involved a NYSE rule that allowed floor brokers to receive a subscription to an electronic feed of closing order imbalance information each day at 3:40 pm.9 Seven months following the May 2008 effective date of the NYSE’s rule, the NYSE revised its systems to provide closing order imbalance information to its operations staff at 2:00 pm. However, when these systems were revised with respect to the operations staff, this feed was mistakenly delivered to floor brokers at 2:00 pm as well.

The SEC stated that, despite knowing that the floor brokers were receiving this information prior to 3:40 pm, the NYSE continued its 2:00 pm dissemination of the information to floor brokers until May 2010 – even after the SEC had informed the NYSE in March 2010 that this earlier dissemination violated the NYSE’s existing rules and required a rule change. According to the SEC, the floor brokers obtained an informational advantage about “which other market participants and the public were not aware.” The SEC found that this conduct violated Exchange Act Section 19(g)(1), which requires an exchange to comply with its own rules. Thus, the Settlement highlights the fact that exchange rules previously approved by the SEC, which may have been relied on by other market participants, must be followed.

Selected Observations Relating to the Settlement

It is clear that the Settlement relates to practices that occurred well before Michael Lewis and the NYAG raised their recent concerns about market integrity. Indeed, much of the alleged conduct that formed the basis for the Settlement occurred between 2005 and 2011. The Settlement is confirmation of SEC Chair Mary Jo White’s comments indicating that the Commission has a number of ongoing investigations regarding “market integrity and structure issues, including high-frequency traders,” which have been under way for “quite some time.”10

The Settlement illustrates both that the SEC has been aware of the potential for informational disadvantages resulting from technology following the adoption of Regulation NMS and that the SEC has worked since at least 2009 to address certain co-location practices that it deemed unfair. The Settlement also illustrates that certain of the practices complained of by Mr. Lewis have not occurred at the NYSE since 2010. While co-location remains a topic of policy discussion, the SEC’s focus on rule filing procedures, rather than the practice of co-location itself, is a reminder that the Commission has approved of co-location. This is in contrast to the position of the NYAG, who has attacked the practice – claiming that “one of the worst problems” his office had discovered was “the tendency for our markets and institutions to start catering to high-frequency traders, and becoming enablers of this particularly dangerous type of trading.”11

While the NYAG has urged the SEC and other regulators to address what he believes to be “unseemly practices in the markets,” the Commission has been focusing on the market-wide impact of electronic and HFT issues for many years now, including some of the specific practices complained of by Mr. Lewis and the NYAG. Chair White has stated that she does not wish to rush to judgment when making changes to complex market rules, but rather “want[s] to do a soup-to-nuts review,” starting with the presumption that “the markets are not rigged” – which also involves weighing any positive effect that HFT has on the markets.12 She testified in recent Congressional hearings that any rule changes in this area will be “supported by data as . . . [the SEC surveys] the entire market, rather than focusing on speed traders."13And, on June 5, 2014, Chair White announced that the SEC will be advancing initiatives addressing several sets of issues, including market instability, high frequency trading (and specifically the use of destabilizing trading strategies that exacerbate price volatility), fragmentation of the trading markets, broker conflicts, the building of quality markets for smaller issuers.14

Although the Settlement focuses on the NYSE, it touches upon issues that are relevant to other market participants as well. During her Congressional testimony last month, SEC Chair White commented that the Commission had been intensifying its review of off-exchange trading venues used by high frequency traders.15 Other non-exchange trading centers – while not subject to the same degree of SEC oversight as exchanges – also have fair access requirements under Regulation ATS, are subject to Rule 603 of Regulation NMS (which addresses the provision of trade information through direct data feeds), and must make sure that they operate in the manner disclosed to participants.16 The Settlement is a reminder that alternative trading platforms also must remain vigilant to ensure that they adhere to such requirements.

Finally, it is evident in a number of the SEC’s charges against the NYSE that technology presents its own unique set of risks, and that lack of coordination between technology developers and the legal and compliance staff can be problematic. Advances in technology require time, attention and understanding by compliance staff to prevent mistakes that may result in regulatory violations.


Regulatory scrutiny of HFT and market structure issues concerning informational advantages is likely to continue. Thus, while the SEC’s Settlement with the NYSE is the first post- "Flash Boys” action regarding market integrity issues, in light of the attention placed on HFT and electronic trading, it is not likely to be the last.
