## Smile

In options, a smile refers to the shape of the volatility curve when plotted against strike prices. It occurs when both deep out of the money calls and puts have higher implied volatility than at the money options.

This shape indicates the market expects large moves in either direction. It is a common feature in many markets.

It helps traders understand the market expectation of volatility.
