What is a low-float scanner?
A low-float stock scanner filters securities using an available estimate of publicly tradable shares, then combines that supply context with current price, volume, market cap, and event conditions. Reported float is not the same as shares available at the next bid or ask.
Who it is for
Built for active traders who verify the evidence.
It is intended for experienced active traders studying smaller companies and volatile moves who understand that thin liquidity, wide spreads, dilution, and trading halts can make risk materially harder to control.
How it works
From changing data to a focused review.
- 1Set a supported float boundary and retain unknown values as unknown.
- 2Combine float with price, market cap, volume, dollar volume, spread, and session conditions.
- 3Compare current volume with reported float only when both inputs are current enough to be meaningful.
- 4Inspect offerings, reverse splits, filings, catalyst quality, liquidity, and halt state before any independent decision.
Capabilities
The information connected to this workflow.
Reported float
Use provider-supplied float when available without silently estimating a missing value.
Float turnover
Compare session volume with reported float as one context measure, not a claim that every share changed hands uniquely.
Liquidity evidence
Keep spread, dollar volume, print activity, and available quote size separate from the float estimate.
Corporate-action risk
Review available offering, filing, reverse-split, shares-outstanding, and halt information near volatile activity.
TraderBase approach
What makes TraderBase different?
TraderBase does not equate low float with a guaranteed runner. The scanner can narrow a supported universe, while the linked context makes uncertainty, missing fields, and liquidity risk explicit.
Common questions
Low-float scanner FAQ
What is a low-float stock?
It is a stock with a relatively small reported estimate of publicly tradable shares. Providers can calculate and refresh float differently, so the source and date matter.
Does low float guarantee volatility?
No. Volatility depends on demand, liquidity, participation, news, market conditions, and other factors. A low reported float alone predicts neither direction nor outcome.
What is float rotation?
Float rotation commonly compares cumulative trading volume with reported float. It is a rough activity ratio, not proof that each tradable share changed hands or that supply is exhausted.
