Beginning today, FINRA is expanding its alternative trading system (ATS) transparency initiative by publishing monthly information on block-size trades occurring on ATSs. The data is available free of charge on FINRA’s website.
Under the initiative to provide additional transparency to over-the-counter (OTC) trading in equity securities, FINRA in June 2014 began publishing on its website volume and trade count information for equity securities executed on an ATS. FINRA began posting the remaining, non-ATS OTC equity volume by member firm and security in April 2016. Starting today, FINRA further adds to this information by publishing monthly ATS block-size trading statistics in all National Market System (NMS) stocks.
“With each additional step, we are providing the investing public and market professionals with greater visibility into ATS trading activity and increasing the transparency of the over-the-counter market,” said Steven A. Joachim, FINRA’s Executive Vice President of Transparency Services. “Greater public understanding of the market helps strengthen investor confidence.”
The statistics for ATS block-size trades are being aggregated across all NMS stocks for a period of one month of trading, and published no earlier than one month following the end of the month for which trading was aggregated.
Rather than narrowly defining what constitutes a block-size trade, FINRA is using both share-based and dollar-based thresholds, as well as thresholds that include both shares and dollar amount, in the following categories:
- 10,000 or more shares
- $200,000 or more in value
- 10,000 or more shares and $200,000 or more in value
- 2,000 to 9,999 shares
- $100,000 to $199,999 in value
- 2,000 to 9,999 shares and $100,000 to $199,999 in value
For each of those categories, FINRA is publishing monthly trade count and volume information for each ATS aggregated across all NMS stocks. FINRA also is displaying the average trade size and each ATS’s rank as well as “ATS Block Market Share” (the proportion of each ATS’s block-size trading volume in relation to total block-size trading by all ATSs) and “ATS Block Business Share” (the proportion of a particular ATS’s overall trading volume that was done as block-size trades) and rankings of those metrics for each category.
The data is being published in two new tabs on FINRA’s existing OTC Transparency Data page, marked “ATS Blocks” and “ATS Blocks Download.” With the one-month publication delay, the reports published today reflect ATS trades during August.
