Stock Float
A stock’s float (often called free float) is measured as the number of shares that are actually available for public trading.
The basic calculation
- Start with Shares Outstanding
- Subtract shares that are not realistically tradable, like:
- Insider/management shares (officers/directors)
- Restricted shares (locked up, not freely transferable)
- Strategic/controlling stakes (a parent company, a founder with control, government holdings)
- Sometimes other “stable” long-term holdings (depends on the data provider’s rules)
So, roughly: Float≈Shares Outstanding−Restricted / Insider / Control Blocks\text{Float} \approx \text{Shares Outstanding} - \text{Restricted / Insider / Control Blocks}Float≈Shares Outstanding−Restricted / Insider / Control Blocks
Two related terms people mix up
- Shares outstanding: all shares issued and held by everyone (public + insiders + institutions).
- Float: the portion that can trade freely.
- Free-float market cap: Float×Share Price\text{Float} \times \text{Share Price}Float×Share Price
