Halt-by-Halt Summary
POM experienced the most halts of any single name on October 21, 2026, with repeated LULD pauses on NASDAQ beginning at 9:35 AM ET. Each POM halt was triggered by volatility, not a pending news announcement. The day's T1 news-pending halts affected CHOW in the early afternoon and AXNX and DKI near the close, both of which remained halted as of publication.
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. A LULD halt is designed to prevent extraordinary price volatility from spiraling out of control.
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. A T1 halt can last minutes or hours depending on when the underlying news is released and digested.
Halt Code Reference
| Code | Name | Description |
|---|---|---|
| T1 | News pending | Regulatory pause pending release of material news |
| T2 | News released | Pause after news release to allow order absorption |
| T12 | Additional information requested | Regulatory halt while exchange requests further information |
| M / LUDP | LULD volatility halt | Limit Up-Limit Down pause triggered by price bands |
| H10 / H11 | Regulatory / SEC | Exchange or SEC-imposed regulatory halt |
| T6 | Extraordinary market activity | Halt due to extraordinary market conditions |
