The SEC recently released a plan to establish a Consolidated Audit Trail (CAT), one of the world’s largest data repositories that will contain a complete record of all equities and options traded in the US. [1] The plan will require national securities exchanges and FINRA (SROs), alternative trading systems (ATSs), and broker-dealers (collectively, CAT Reporters) to submit information on trade events, [2] including customers and prices, to the CAT on a daily basis. It is estimated that the CAT will aggregate between 30 billion and 120 billion trade events per day from over 2,000 sources.
The SEC first proposed the CAT after the May 2010 “flash crash” when it became clear that the data available to the SEC is fragmented with no single source that covers all SEC regulated markets. [3] As a result, the SEC mandated the SROs to develop a plan to create the CAT, which will enable the SEC to conduct cross-market surveillance and reconstruct market events more efficiently. The plan is currently in the midst of a 60-day comment period, [4] after which the SEC will have 120 days to approve it. Once approved, SROs will have two months to select a vendor who will build and maintain the CAT (Plan Processor). [5]
