Trading Halts Today: September 1, 2026 — 34 Stocks Halted (LULD & T1)

TL;DR: As of 9:45 PM ET on September 1, 2026, Tapeboard tracked 34 trading halts during the session. The most recent halt was RIBBU, paused under a Limit-up/limit-down pause at 2:14 PM ET.

September 1, 2026 saw 34 trading halts across U.S. exchanges: 28 LULD/volatility pauses, zero T1 news-pending halts, and 6 other regulatory halts. The most newsworthy was ACHR.W, which was halted at 10:08 AM ET under code H11 — a regulatory/SEC halt — and had no resumption on file as of publication. The bulk of the day's activity was volatility-driven: FGL triggered a circuit breaker six separate times between 9:32 AM and 10:30 AM ET, the most repeat LULD halts of any single name today. SOWG, ANPA, XXII, and RDACU each triggered a circuit breaker twice. Five names — CRK, ALMS, GPRO, BWLP, and ITP — were paused under T3 (resumption-of-trading-related) codes, and all five have since resumed. No T1 halt was issued today, meaning no stock was paused pending material news.

Halt-by-Halt Summary

ACHR.W was the day's standout: an H11 regulatory/SEC halt issued by NYSE at 10:08 AM ET with no resumption on file as of 9:45 PM ET, making it the only halt still pending. Unlike the day's LULD pauses, an H11 halt is not volatility-driven and carries no fixed duration. FGL was the most frequently halted name, triggering six LULD pauses in under an hour — each a standard five-to-ten-minute volatility pause, all of which resumed the same morning. The five T3 halts (CRK, ALMS, GPRO, BWLP, ITP) were exchange-issued resumption-process pauses, and all have since resumed trading.

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.
