Regulation FD
Regulation FD addresses selective disclosure of material nonpublic information by covered U.S. issuers and people acting on their behalf.
Securities-market rule terms for fair disclosure, short-sale regulation, margin regulation, anti-fraud liability, and resale exemptions.
Trading and Market-Conduct Rules is the regulation landing page for SEC disclosure, short-sale rules, margin-credit rules, fund distribution fees, issuer repurchase rules, and trading conduct rules. It keeps related terms in one branch so readers can move from a broad compliance question to the article that owns the regulatory evidence.
Use this page when a securities-market rule changes disclosure, trading, margin, issuer activity, or distribution practices. Use the parent Securities Market Rules and Disclosure page when you need the broader regulation map. For an individual decision, confirm the rule source, jurisdiction, covered party, effective date, filing or record, and compliance consequence before relying on the term.
