The sell side long has had limited answerability to the buy side in terms of trade handling and routing practices. Brokers have a fiduciary duty to achieve best execution on every trade, and they want to make clients happy, but providing information about the logic behind why a given trade went where it did is ultimately at the broker’s discretion. This changes on June 1, when U.S. Securities and Exchange Commission [Rule 606](https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.sec.gov%2Fnews%2Fpress-release%2F2018-253&data=02%7C01%7CJSchrader%40clearpoolgroup.com%7C9d0d0c4d7ced4aad492708d7d5708780%7Ced76c590becd435890abfe864ca4276b%7C0%7C0%7C637212551602584342&sdata=2mUtHj3HZQKRtXFeMTurumMarXtDbd825D69LaD3Wao%3D&reserved=0)(b)(3) is scheduled to go into effect, reflecting a two-month delay due to the effects of Covid-19. The rule requires a broker-dealer, upon request of a customer that places not held orders, to provide specific disclosures, for the prior six months, regarding routing and execution of such orders. The intent behind 606(b)(3) is simple: to help buy-side investment managers trade more efficiently by empowering them with more data and information about their trades.

The report will also cover the buy side’s access to unique liquidity sources and their brokers’ capability of managing liquidity workflows. Once 606(b)(3) is in place, regulators will first survey the sell side to make sure brokers are gathering, collating, and disseminating the appropriate data on a timely basis. After that, attention will turn to the buy side, regarding what data they are using and how they are using it.
