Securities Information Processor (“SIP”) Operating Committees are considering a proposal for the SIPs to disseminate certain consolidated odd lot quotation data as ancillary information on the SIP data feeds. They are seeking feedback on the below draft proposal.
The Participants of the Nasdaq Unlisted Trading Privileges (UTP) Plan and the Consolidated Quotation (CQ) Plan operate the SIPs that are responsible for disseminating the national best bid and national best offer (NBBO) for quotations in NMS stocks. Pursuant to Regulation NMS, the NBBO as disseminated by the SIPs is calculated using bids and offers to buy or sell one or more round lots of an NMS stock1. Round lots are defined by the exchanges and generally refer to quotes to buy or sell 100 shares of a given security or a larger number of shares divisible by 100. Odd lots, or orders for fewer than 100 shares, are not included in the NBBO and are not currently distributed by the SIPs.
Over the past several years, the U.S. equity markets have transformed in a number of ways. One important development has been the significant increase in odd lot activity, which has come to account for an increasing portion of U.S. equity trading volume, particularly for high-priced securities2. Given the higher levels of odd lot activity, the Participants are considering ways to enhance the transparency of odd lot data. As an initial first step, the Participants are considering a proposal for the SIPs to disseminate certain consolidated odd lot quotation data as ancillary information on the SIP data feeds. The Participants believe that this new published data may provide market participants with important additional information about the price and liquidity of NMS stocks, and may be valuable for retail investors that trade in smaller share amounts, particularly in higher-priced securities.
Details on the Participants’ proposal are contained in the document below.
1. The NBBO is defined under Rule 600(b)(43) of Regulation NMS to mean, “with respect to quotations for an NMS security, the best bid and best offer for such security that are calculated and disseminated” by the SIP Plans. “Bid” and “offer” are in turn defined under Rule 600(b)(9) to mean the bid price or offer price at which an exchange or FINRA member is “willing to buy or sell one or more round lots of an NMS security.”
2. For example, a recent market structure analysis, using data from the SEC’s Market Information Data Analytics System (MIDAS), found that odd lot trading in U.S. stocks increased from 5.7% of volume and 21% of trades in 2013 to almost 11% of volume and 38% of trades in 2018. See Deutsche Bank, There’s More to Odd Lots than High-Priced Stocks… (June 25, 2019).
