Monday, February 1, 2021 A December 16, 2020 risk alert issued by the SEC’s Office of Compliance Inspections and Examinations (OCIE) cautions investment advisers and broker-dealers to review and, as necessary, enhance their compliance programs with respect to “Large Trader” obligations pursuant to Rule 13h-1 under the Securities Exchange Act of 1934. Compliance with Rule 13h-1 enables the SEC to identify and obtain information on market participants that conduct a substantial amount of trading activity, as measured by volume or market value, in national market system (NMS) securities—i.e., “Large Traders.” Rule 13h-1 requires entities and individuals, such as investment advisers, whose transactions in NMS securities meet or exceed the daily or monthly thresholds identified by the rule to self-identify to the SEC on Form 13H, and also requires certain recordkeeping, reporting and monitoring responsibilities for broker-dealers.
