The volatility smile is a graphical representation of the implied volatility of options across different strike prices for the same expiration date. It typically shows that implied volatility is not constant across all strike prices; instead, it often exhibits a "smile" shape, where options that are either deep in-the-money or out-of-the-money tend to have higher implied volatilities compared to at-the-money options.
