IV leaders
Updated 16:52
Which F&O stocks' options are priced for the biggest and smallest moves, and where implied volatility is changing fastest today.
At-the-money implied volatility worked out from each stock's live ATM straddle (212 F&O stocks). Stocks whose at-the-money options hardly trade are left out: their prices are too old to give a true IV. Information only, not investment advice.
What is IV?
Implied volatility is the yearly move the option price assumes. High IV means expensive options: the market expects big moves, often before results or news.
Why does IV jump near expiry?
With very little time left, small price changes swing the IV figure a lot, so stocks close to expiry are marked.
