A low float stock is a stock with relatively few shares available for public trading. The fastest way to find one is to use a screener with a Float or Free Float filter, then verify the share count against the company's latest SEC filings. Start with a threshold such as under 10 million, 20 million, or 50 million shares, add liquidity and volume filters, and check for dilution before considering a trade.
A low float stock is not necessarily a low-priced stock, a low-market-cap stock, or a stock with high short interest.
Low Float Stocks at a Glance
| Metric | What to check | Practical starting point |
|---|---|---|
| Float shares | Shares available for public trading | Under 10M, 20M, or 50M |
| Average volume | Typical number of shares traded each day | High enough for your order size |
| Average dollar volume | Average volume multiplied by share price | Prefer liquid names |
| Relative volume | Current activity compared with normal volume | Above 1.0 for unusual activity |
| Dilution risk | New shares, warrants, convertibles, or offerings | Review recent SEC filings |
| Reason for activity | News, earnings, contracts, approvals, or sector movement | Look for a clear explanation |
These figures are starting points for a screen, not formal definitions. No universal share count defines a low float stock.
What Does Low Float Mean?
Float shares are the shares available for public trading after excluding shares that are closely held, restricted, or otherwise unavailable to ordinary market participants. TradingView describes free float as issued common shares available for open trading. Total shares outstanding can also include insider, institutional, employee, and restricted holdings.
The term public float can also have a regulatory meaning. The U.S. Securities and Exchange Commission generally calculates public float as the market value of common equity held by non-affiliates. That dollar-value calculation is not always the same as the float-share figure shown by a stock screener.
A simplified calculation is:
Estimated float shares =
total shares outstanding
- closely held shares
- insider or affiliate shares
- restricted or otherwise unavailable shares
Data providers can apply different rules. Finviz, for example, describes its float calculation as shares outstanding minus insider shares, holders of more than 5%, and Rule 144 shares.
How to Find Low Float Stocks With Finviz
Finviz is a practical starting point because its stock screener includes filters for Float, Shares Outstanding, Average Volume, Relative Volume, Current Volume, Price, Market Capitalization, and Short Float.
Use this process:
- Open the Finviz stock screener.
- Select the exchanges or countries you want to search.
- Choose Float and set an initial limit, such as:
- Under 10 million shares for a very small float
- Under 20 million shares for a tighter list
- Under 50 million shares for a broader search
- Add a minimum price if you want to exclude the lowest-priced stocks.
- Add Average Volume to remove stocks that rarely trade.
- Add Relative Volume or Current Volume if you want stocks that are active today.
- Sort the results by relative volume, performance, or average volume.
- Review each candidate before placing a trade.
A sample screen could look like this:
Exchange: Nasdaq or NYSE
Stock type: Common stock
Float: Under 20 million
Price: Above $1
Average volume: Above 250,000 shares
Relative volume: Above 1.0
These are example filters, not universal requirements. A larger position needs more liquidity than a small one.
How to Find Low Float Stocks With TradingView
TradingView lets users build custom stock screens by selecting the market, security type, technical data, and market-data columns. Its documentation also supports filtering by market and primary listing, which can help reduce duplicate or secondary listings.
A practical TradingView workflow is:
- Open Stock Screener.
- Select the United States market.
- Choose Common stock instead of preferred stock, funds, or other security types.
- Enable the primary listing setting if you want to avoid duplicate listings.
- Add the Free Float or Float field if it is available in your screener view.
- Add:
- Average volume
- Turnover or average dollar volume
- Relative volume
- Price
- Market capitalization
- Gap or performance filters
- Save the screen so you can run it again.
TradingView explains that free float can affect liquidity and volatility because a smaller pool of tradable shares can make large orders more influential in the market.
The Three Calculations That Matter Most
1. Float Percentage
Float percentage = float shares ÷ shares outstanding × 100
Example:
- Shares outstanding: 40 million
- Float shares: 8 million
8 million ÷ 40 million = 20%
A company can have many shares outstanding but a relatively small float percentage if insiders or major shareholders control much of the stock.
2. Float Turnover
Float turnover = daily trading volume ÷ float shares
Example:
- Float: 5 million shares
- Daily volume: 1 million shares
1 million ÷ 5 million = 20%
Daily trading volume in this example equals 20% of the stated float. High float turnover can show unusual interest, but it can also occur during sharp price moves and difficult execution.
3. Average Dollar Volume
Average dollar volume = average daily volume × share price
Example:
- Average volume: 500,000 shares
- Share price: $4
500,000 × $4 = $2 million average daily dollar volume
Average dollar volume is often more useful than share volume. Five hundred thousand shares of a $1 stock represents much less traded value than 500,000 shares of a $10 stock.
Why Float Alone Is Not Enough
A stock can have a low float and still be unsuitable for a trade. Other problems may include:
- Very wide bid-ask spreads
- Low average dollar volume
- Little order-book depth
- Frequent price gaps
- Unclear financial disclosures
- A pending stock offering
- Large numbers of warrants or convertible securities
- A recent reverse split
- A promotional or speculative trading history
The SEC warns that many microcap stocks trade at low volumes. Even a relatively small trade can therefore have a large percentage effect on the price.
Use the float filter to create a shortlist. It is not a complete trading strategy.
How to Verify a Stock's Float
Screener data can be delayed or calculated differently from the company's own disclosures. Verify promising candidates with the latest filings in the SEC's EDGAR database.
Check these documents:
Latest Form 10-K or Form 10-Q Look for the current number of shares outstanding and the reporting date.
Proxy statement or ownership disclosures Review insider ownership and shareholders holding large positions. Form 10-K Item 12 commonly covers security ownership of certain beneficial owners and management, although some companies incorporate this information from their proxy statement.
Recent Form 8-K filings Look for financing transactions, mergers, share issuances, or other changes to the capital structure.
Registration statements and prospectus supplements Check for an active shelf registration, an at-the-market offering, warrants, convertible notes, or a resale registration.
Corporate action notices Review recent reverse splits, stock splits, ticker changes, and share retirements.
The share count can change after a financing, stock-based compensation, acquisition, warrant exercise, conversion, buyback, or split. TradingView also notes that total common shares outstanding can change over time and is generally sourced from company reports.
A Low Float Stock-Screening Formula
A useful screen combines:
Low float
+ adequate average dollar volume
+ current relative volume
+ a clear reason for activity
+ no immediate dilution risk
= stronger candidate for further research
For example, you might screen for:
- Float under 20 million shares
- Average volume above 250,000 shares
- Relative volume above 1.0
- Price above $1
- A recent earnings report, contract, regulatory event, sector move, or other clear reason for activity
- No obvious pending offering or large supply of exercisable warrants
A reason for activity does not guarantee a price increase. It only explains why the stock may be receiving attention.
Low Float Stocks Versus Related Terms
Low Float Versus Low-Priced Stock
A $2 stock can have hundreds of millions of shares outstanding. A $50 stock can have only a few million shares in its float. Share price does not determine float.
Low Float Versus Low Market Capitalization
Market capitalization equals share price multiplied by shares outstanding. A company can have a low float and a higher market capitalization if its share price is high.
Low Float Versus High Short Interest
Float measures available shares. Short interest measures shares sold short. They are different metrics. A low float stock may have high short interest, but low float alone does not create a short squeeze.
Low Float Versus Low Liquidity
A low float can contribute to low liquidity, but trading activity also depends on volume, market makers, spreads, institutional interest, and current investor demand.
Main Risks to Manage
Low float stocks can move quickly in either direction. The same limited supply that can amplify an upward move can also make an exit difficult when buyers disappear.
The main risks are:
- Slippage between the expected price and execution price
- Large spreads that increase trading costs
- Rapid price gaps
- Trading halts or a temporary loss of liquidity
- Dilution from new shares, warrants, or convertible securities
- Float data that is outdated or calculated differently by each provider
- Promotional activity that creates temporary volume without lasting demand
Use limit orders where appropriate, size positions conservatively, and check the current bid-ask spread before entering. A low float is a volatility characteristic, not a guarantee of momentum or profitability.
Bottom Line
To find low float stocks, use Finviz, TradingView, or your broker's stock screener to filter by float shares. Start with a threshold such as under 20 million shares, add average volume and relative volume filters, calculate average dollar volume, and verify the latest share count and ownership structure through SEC filings.
The stronger candidates usually combine a small float with real liquidity, a clear reason for activity, and limited near-term dilution risk. A low float by itself is not enough.
