A stock trading halt is a temporary suspension of trading of a security imposed by regulators or exchanges. A trading halt may occur for a number of reasons, such as extreme price volatility or when the market is awaiting a substantial news release.
Where can I find more information about current trading halts?
Information about current and historical trading halts, including the reasons for the halts, can be found on the NYSE and Nasdaq websites.
Can I place trades during a halt?
You can still place trades during a halt but they will not be processed until the halt is removed. Market orders placed during a trade halt will be queued to execute when trading resumes.
