Implied Volatility
Implied volatility (IV) is a measure of the market’s expectations for future price fluctuations of a security or index, as inferred from the prices of options.Higher implied volatility suggests that the market expects larger price swings, while lower implied volatility indicates smaller expected movements. Implied volatility is a critical component in option pricing models, as it helps investors assess the likelihood of significant price changes and adjust their strategies accordingly.
Example
If an option on a stock has high implied volatility, it suggests that the market expects significant price movements, which could impact the option’s premium.
