Halt-by-Halt Summary

The headline event is the after-hours T1 cluster: ten NASDAQ-listed names were halted news pending at 7:50 PM ET, and none had a resumption on file as of 9:45 PM ET. T1 halts carry no fixed duration and lift only when the exchange is satisfied the news has been disseminated. During regular hours, BANL was the most-halted single name with six LULD pauses in under an hour, followed by IPEX and TANH with three each — all standard five-to-ten-minute volatility pauses, not regulatory actions.

What Is an LULD Halt?

A Limit Up-Limit Down halt pauses trading when a stock's price moves more than a defined percentage away from its recent five-minute average. The bands are 5% for most large-cap S&P 500 names, 10% for smaller stocks, and 20% for stocks under $3. Most LULD halts last five minutes.

What Does a T1 Halt Mean?

A T1 halt is a regulatory pause pending the release of material news. It has no fixed duration and resumes when the exchange determines an orderly market can be maintained.
