IV Crush

Options & Volatility

IV crush refers to the rapid decline in implied volatility that typically occurs immediately after a major event such as an earnings release. As the uncertainty resolves, the options market rapidly deflates the premium that had been priced in.

Even if a stock moves after earnings, IV crush can wipe out an option's value — because you bought at peak IV right before it collapsed. Understanding IV crush is fundamental to any earnings options strategy.
