Small-cap stocks on August 20, 2026: gappers, halts and filings
On August 20, 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 JZ, up 113.5% at 9:30 a.m. ET.
Pre-market gappers
The small caps up the most at 9:30 a.m. ET, the open: the price then 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.

The real Level 2, time and sales and chart from 9:17 a.m. to 9:29 a.m. ET, from the same feed the replay plays. It stops at 9:20 a.m. and asks what you would do, then plays on.
