Float — the Shares Actually Trading
Not all shares trade
Float = shares available for public trading, excluding insider holdings, restricted stock and controlling stakes. A company can have 1B shares outstanding but only 300M floating. Thin float means: bigger price swings on modest buying/selling, wider spreads, and violent squeezes when sentiment flips.
Float and volatility
This is why some stocks move 15% on routine news while others move 2% on the same news. Low float amplifies everything — up and down. GameStop in 2021 was an extreme float-and-squeeze case. For a beginner: high float mega-caps are more forgiving; low-float small-caps punish mistakes faster.
What you'll practise
Two companies have identical market cap. The one with a smaller public float will generally be LESS volatile.
