Implied volatility
The yearly volatility that today’s option prices imply. Higher IV means pricier options.
Why it matters
IV is the market’s guess at how much the stock will move. It rises before earnings and in sell offs, and falls when things calm down.
How to read it
Compare IV with the stock’s own history (IV rank) and with how much it has actually been moving (historical volatility).
