NASDAQ Stock Market Rules require that, except in unusual circumstances, companies make prompt disclosure to the public through any Regulation FD-compliant method (or combination of methods) of disclosure of any material information that would reasonably be expected to affect the value of its securities or influence investors' decisions. MarketWatch implements fair and independent decisions within the scope of its authority and without influence from other NASDAQ offices. Information received by MarketWatch is confidential and used strictly for regulatory purposes. When activity is suspected of being potentially in violation of Exchange rules, MarketWatch refers the activity to FINRA's regulatory groups for further review and potential disciplinary action. MarketWatch works closely with NASDAQ business lines and FINRA in an effort to provide innovative, fair and equitable regulation for the NASDAQ markets. MarketWatch maintains a suite of post-trade surveillance patterns covering the NASDAQ markets. In addition, MarketWatch monitors compliance with Exchange rules and policies through real-time surveillance of price and volume information reported by market participants in equities and options transactions.

In an effort to foster marketplace integrity, MarketWatch oversees the complete and timely disclosure of material information by NASDAQ-listed companies. Additional MarketWatch staff work on the NASDAQ PHLX trading floor providing similar coverage for electronic and floor based trading on NASDAQ PHLX. NASDAQ MarketWatch provides real-time surveillance for activity on the NASDAQ Stock Market, NASDAQ BX, NASDAQ PSX, NASDAQ Options Market and the NASDAQ BX Options Market to maintain an orderly marketplace and level playing field for investors, market participants and listed companies.

Nasdaq operates a multifaceted surveillance program including real-time surveillance, post-trade surveillance, testing of exchange trading system to confirm alignment with exchange rules, membership application reviews, and oversight of examination, investigation and legal services outsourced to FINRA, an independent securities industry regulatory authority.
