Halt-by-Halt Summary

The standout symbol today was PLAG, which experienced 20 separate volatility pauses (reason code M) on AMEX, spanning from 10:12 AM through 3:45 PM ET. These are LULD volatility halts, not news-driven, indicating sustained price movement outside the defined bands. The other notable cluster was RETO and PYXS, each triggering multiple limit-up/limit-down pauses on NASDAQ within a short window in the early afternoon.

What Is an LULD Halt?

A LULD 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.
