who does FINRA regulate
FINRA regulates trading in equities, corporate bonds, securities futures, and options. All firms dealing in securities that are not regulated by another SRO, such as by the Municipal Securities Rulemaking Board (MSRB), are required to be member firms of the FINRA.n July 2007, the SEC approved the formation of a new SRO to be a successor to NASD. The NASD and the member regulation, enforcement and arbitration functions of the New York Stock Exchange were then consolidated into the Financial Industry Regulatory Authority (FINRA).
