Small-cap stocks on October 19, 2026: gappers, halts and filings
On October 19, 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 YMAT, up 94.7% at the open.
Pre-market gappers
Fewer than three small caps met the rule at 9:30 a.m. ET, so there is no list.
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.
Play the moment: WORX at 10:04 a.m. ET
The real Level 2, time and sales and chart from 10:01 a.m. to 10:13 a.m. ET, from the same feed the replay plays. It stops at 10:04 a.m. and asks what you would do, then plays on.
Gainers
The small caps up the most from the previous close at 4:00 p.m. ET, the close.
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.
Or in play: up 30% or more at any moment on $3 million or more really traded, whatever its price, relative volume or float, its high at $1 or more.
