Market Disclosure

Disclosure and transparency rules for financial markets, including EU investment directives and market-abuse controls.

Market disclosure terms explain how financial systems force information into the open. The section covers transparency rules, reporting obligations, and the legal frameworks that shape how investment firms, trading venues, and market participants disclose information.

The EU investment-regulation branch underneath this landing page groups the Investment Services Directive, MiFID, MiFID II, and the Market Abuse Regulation together because they form a connected rule set for cross-border market access, transparency, and market integrity.

This section now also includes a securities-market-rules branch for Regulation FD, Regulation SHO, and Regulation T, because those pages share a disclosure-and-trading-control theme that reads better together than in the old alphabet structure.

That branch now also houses the related SEC rule pages for insider trading plans, stock repurchases, mutual fund distribution fees, and restricted-securities resales so the SEC material reads as one rule family.
