Frequently asked
What are these stock screeners?
Free daily lists of small-cap stocks (priced roughly $1–$20 with real volume) that stand out today — the biggest gainers, losers, gap-ups, gap-downs, most active, and stocks on winning or losing streaks. Each list is explained in plain English.
How often are they updated?
Every trading day. The lists are rebuilt from a full end-of-day scan of the US market after the close, so they reflect the latest completed session.
Why small-cap stocks specifically?
Small caps move far more than large caps day to day, so they dominate the biggest-mover and gap lists. It's also a niche the big finance sites cover poorly in plain English.
Are these buy or sell recommendations?
No. Every screener is descriptive and educational — it reports what happened, not what to do. Small-cap stocks are volatile; always do your own research.
