What Is Triple Witching? Complete Guide to Quarterly Options Expiration

Triple witching is one of the most significant events in the options and futures markets. It occurs quarterly and can cause substantial volatility and trading volume as multiple types of derivatives expire simultaneously.

Understanding triple witching is important for traders and investors because it can create unique trading opportunities and risks. This guide explains what triple witching is, when it occurs, and how to trade around it.

What Is Triple Witching?

Triple witching is a quarterly event when three types of derivatives expire on the same day:

When all three expire simultaneously, it creates a "triple witching hour"—the last hour of trading on expiration day, which can see extreme volatility.

When Does Triple Witching Occur?

Triple witching occurs on the third Friday of March, June, September, and December each year. These are the quarterly expiration dates for options and futures contracts.

The term "witching" refers to the volatility and unpredictability that can occur during these expiration periods.

How Triple Witching Affects Stock Markets

Triple witching can cause several market effects:

• Increased volume: Trading volume typically spikes as traders close or roll over expiring positions
• Price volatility: The last hour of trading (3:00-4:00 PM ET) can see extreme price swings
• Pin risk: Stock prices may be "pinned" to strike prices as options expire
• Unusual price action: Stocks may move in ways that don't reflect fundamental news
• Reversal patterns: Prices may reverse direction after expiration as hedging activity ends
