Implied Volatility
Implied volatility is the market's pricing of expected movement, and it changes option prices even when the stock barely moves.
#options#implied volatility#pricing
Implied volatility, usually called IV, is the market's estimate of expected movement in the underlying. In options, that estimate changes price.
Why traders care
Higher IV usually means more expensive options. Lower IV usually means cheaper options.
What beginners get wrong
Many new traders think direction is everything. It is not. A correct direction read still loses money when implied volatility contracts after the trade is placed.
Practical takeaway
Check IV when you are comparing contracts, planning earnings trades, or wondering why an option feels expensive.
