NYSE Rule 7.18

Key Requirements:

• Authorizes the Exchange to halt trading in a security when necessary to maintain fair and orderly markets.
• Specifies circumstances that may warrant a halt, including:
  • regulatory concerns;
  • material news events;
  • operational issues;
  • extraordinary market conditions; and
  • situations where additional time is needed for investors to evaluate significant information.
• Establishes procedures for implementing, maintaining, and lifting trading halts.
• Coordinates with market-wide circuit breaker rules and other regulatory halt mechanisms when applicable.
• Supports the broad dissemination of material information and helps prevent disorderly trading during periods of uncertainty or significant market events.
• Works in conjunction with reopening procedures that govern the resumption of trading after a halt.
• The NYSE merged Rule 123D into Rule 7.18 as part of a broader regulatory update
