Small-cap stocks on August 27, 2026: gappers, halts and filings

On August 27, 2026, these are the small-cap stocks that moved, read from the same data the replay plays: the pre-market gappers, the day's gainers, intraday runners, losers and fades, the after-hours movers, every halt, and the offerings and splits filed or in effect. A day's high runs from 4 a.m., pre-market included, to the 4 p.m. close. The biggest gapper was PPCB, up 229.9% at the open.

Pre-market gappers

The small caps up the most before the bell: picked at 9:30 a.m. ET by their price then against the previous close, shown by their gap at the open, the official opening trade against the previous close.

The small-cap rule: price from 2 to 20 dollars, gapped up 10% or more before the open, relative volume 5× or more, float under 20 million shares.

Gainers

The small-cap rule: price from 2 to 20 dollars, up 10% or more on the day, relative volume 5× or more, float under 20 million shares.

Intraday runners

The small caps whose high from 4:00 a.m. to 8:00 p.m. ET, pre-market and after hours included, was the furthest above the previous close, wherever they finished: a stock that spiked before the bell, during the day or after the close and gave it back is here.

The small-cap rule: the high priced from 2 to 20 dollars, a high 10% or more above the previous close, held by at least 3 one-minute bars that closed at or above that level on 100 shares or more, relative volume 5× or more, float under 20 million shares.
