On August 20, 2026, Tapeboard tracked 50 trading halts across NYSE, NASDAQ, and other U.S. market centers: 42 LULD/volatility halts, 7 T1 news-pending halts, and 1 other regulatory halt. The most newsworthy development came late in the day, when seven NASDAQ names — BTOG, LIMN, LIMNW, XCH, SMTK, ELAB, and SCNI — were simultaneously placed under a T1 halt at 7:50 PM ET pending material news. During regular hours, small-cap volatility dominated: ADXN triggered a circuit breaker five separate times, and FBDT and BRLS each triggered a circuit breaker five times as well, making them the session's most frequently paused names. The bulk of the day's halts were LULD halt events — automatic five-minute volatility pauses — concentrated in low-priced NASDAQ names.

Halt-by-Halt Summary

The most notable events of the session were the seven T1 news-pending halts issued simultaneously at 7:50 PM ET for BTOG, LIMN, LIMNW, XCH, SMTK, ELAB, and SCNI. Unlike the day's LULD volatility halts, these are regulatory pauses with no fixed duration; each will resume when the exchange determines that material news has been disseminated and an orderly market can be maintained. Earlier in the session, GWH was halted under a T3 code on NYSE at 1:07 PM ET — the day's only non-LULD, non-T1 regulatory halt — while ADXN, FBDT, and BRLS each triggered a circuit breaker five times, the most repeat volatility halts of any names on August 20, 2026.

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.
