Deep Tide TechFlow News: On March 17, according to the SEC official website disclosure, the U.S. Securities and Exchange Commission formally proposed on March 16 to revise Rule 15c2-11 of the Securities Exchange Act, intending to clearly limit the scope of application of this rule to equity securities. Since its enactment, this rule has primarily been used to regulate brokers' information collection and due diligence obligations for publishing quotations in the over-the-counter (OTC) market, with the core purpose of preventing manipulative and fraudulent trading activities in the OTC stock market. SEC Chairman Paul S. Atkins stated that regulatory rules should match the asset classes to which they apply. This revision aims to clarify the regulatory obligations for publishing quotations and confirm that Rule 15c2-11 has always applied only to equity securities.
