Securities exchanges, such as the New York Stock Exchange NYSE as well as the Nasdaq Stock Market, have the authority to halt and delay trading in a security.

A trading delay or "delayed opening" is called if either of these situations occurs at the beginning of the trading day. There are two types of trading halts and delays—regulatory and nonregulatory.

By halting or delaying trading, market participants can have time to assess the impact of the news. Nonregulatory halts or delays occur on exchanges, such as the NYSE but not on Nasdaq , when there is a significant imbalance in the pending buy and sell orders in a security.

When an imbalance occurs, trading is stopped to alert market participants to the situation and to allow the exchange specialists to disseminate information to investors concerning a price range where trading may begin again on this exchange.

A nonregulatory trading halt or delay on one exchange does not preclude other markets from trading this security. You can find out what stocks have had their trading halted on the NYSE and the Nasdaq Stock Market , as well as on the OTC Bulletin Board.
