Exchanges can earn revenue from two related services: per-share transaction fees and monthly subscription fees for market data and technology. Because trading activity on an exchange and the market data produced by this activity are a single “platform,” these exchange services must be analyzed holistically. This principle motivates our all-in cost to trade analysis, showing that in total these different, but related, types of fees can yield a lower per-share overall fee than some other venues that, for example, only charge transaction fees.
Earlier this year, the Staff of the SEC’s Division of Trading and Markets issued “Staff Guidance on SRO Rule Filings Relating to Fees.” This guidance acknowledges that platform competition provides a basis to demonstrate a competitive environment when analyzing potential fee changes. However, the SEC staff has advised that in order to rely on platform competition in a fee filing, an exchange must provide data and analysis demonstrating that its aggregate return is constrained by competition on the platform level.
The NYSE retained a third-party expert on industrial organization and competition, Marc Rysman, Professor of Economics at Boston University, to analyze how platform economics applies to stock exchanges’ sale of market data products and trading services, and to explain how this impacts the assessment of competitive forces affecting the exchanges’ data fees. Professor Rysman was able to analyze exchange data that is not otherwise publicly available in a manner that is consistent with the exchanges’ confidentiality obligations to its customers. A copy of Professor Rysman’s paper is available here (“Rysman Paper”): http://sites.bu.edu/mrysman/research/.
Professor Rysman concluded that empirical evidence confirms that stock exchanges are platforms for data and trading.
Based on this empirical evidence, Professor Rysman concluded that data fees, data use, trading fees, and order flow are all interrelated, and that the platform nature of stock exchanges means that data fees cannot be analyzed in isolation, without accounting for the competitive dynamics in trading services.
“[D]ata is more valuable when it reflects more trading activity and more liquidity-providing orders. These linkages alone are enough to make platform economics necessary for understanding the pricing of market data.” (Rysman Paper ¶ 95)
“The platform nature of stock exchanges means that data fees cannot be analyzed in isolation, without accounting for the competitive dynamics in trading services.” (Rysman Paper ¶ 98)
We have observed a similar correlation among trading and data with respect to the NYSE National exchange. Since launching in May 2018, NYSE National has grown to nearly 2% market share and captured a meaningful share of “taker/maker” order flow. Over this same period, NYSE National has had more than a four-fold increase in the number of subscribers to the NYSE National Integrated Feed.
Consistent with the SEC staff’s recent fee-filing guidance, NYSE is submitting Professor Rysman’s paper in connection with market data fee filings that would both lower fees (for data recipients that pay an access fee for display-only use of the BBO and Trades products of NYSE, NYSE Arca, and NYSE American) and introduce new fees for the NYSE National Integrated Feed market data product. These fee filings were filed with the SEC on December 4, 2019 and are available here:
Multi-list options broke nearly all volume records in 2021, driven by the growth of retail participation: daily records (24 of the top 25 volume days of all-time came in 2021), monthly ADV records (April was the only month from 2021 not in the top 12 all-time), and yearly ADV records (37.3M ADV in 2021 was nearly 10M more than in 2020 and double the ADV in 2019).
Increased retail activity in the equities market has affected which stocks are trading the most, and when and where those stocks trade. We’ve previously highlighted retail’s impact on pre- and post-market volume and the opening auction, and now focus on the period immediately after the opening auction. Market participants often avoid this time of day due to higher volatility, an approach worth re-evaluating given current trends.
As the home of ETFs, the NYSE continuously works to strengthen market quality and provide the optimal trading environment for listing and trading ETFs. In April 2021, in service of this goal, the NYSE introduced new requirements and incentives for its industry-leading NYSE ETF Liquidity Program, including the assignment of additional market makers ("Less Active ETF Leads") for new and/or low-volume ETFs.
