Halt-by-Halt Summary

VMAR was halted under code T1 (news pending) at 7:50 PM ET on NASDAQ and remains halted as of publication — a regulatory pause, not a volatility event, with no fixed duration. BRUNW was the session's other T1 halt, issued at 10:25 AM ET, and NTZ was halted under H11, a regulatory code, at 4:09 PM ET on NYSE; neither has a reported resumption. The remaining 34 halts were LULD/volatility pauses, concentrated in a handful of repeat names — AIXI and ADBT (four halts each), SMTK and JEM (three each) — which is typical of low-float small caps on active days.

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.
