Halt-by-Halt Summary
MBRX entered a T1 halt at 7:50 PM ET on October 19, 2026, pending the release of material news. As of publication, the halt remained in effect with no resumption time reported. This was a regulatory/news halt rather than a volatility-driven LULD pause.
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 triggered automatically by exchange circuitry when price bands are breached.
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 is commonly used ahead of earnings, acquisitions, or other corporate announcements.
Halt Code Reference
| Code | Name | Description |
|---|---|---|
| T1 | News pending | Regulatory pause pending release of material news |
| T2 | News released | Pause following dissemination of material news |
| T12 | Additional information requested | Regulatory pause while exchange requests more information |
| M / LUDP | LULD volatility halt | Limit Up-Limit Down pause triggered by price band breach |
| H10 / H11 | Regulatory / SEC | SEC or exchange-initiated regulatory trading pause |
| T6 | Extraordinary market activity | Halt due to extraordinary market conditions |
