The proposal also sets out factors the Exchange would consider when deciding if conduct is disruptive or manipulative, describes activities that alone would not violate the rule, and includes interpretations and policies to guide enforcement if the rule is approved.
SEC temporarily suspends Cboe Rule 8.23
The Securities and Exchange Commission temporarily suspended Cboe Exchange's proposed Rule 8.23 on March 20, 2026, pausing its immediate effect while the SEC reviews it. The proposal had been filed on January 20, 2026 and published for comment on February 2, 2026; the suspension allows the SEC up to 60 days after filing to halt the rule while it considers investor protection and competition standards.
