Understanding Free Float

Free float refers to the portion of a company's shares that are available for trading by the public. It excludes shares held by major shareholders, insiders, and restricted stock. Free float is important for index inclusion, liquidity analysis, and understanding true market capitalization.

Free Float Market Cap

  • Free Float Market Cap = Free Float Shares × Share Price
  • Represents the actual market value available for trading
