Today marks the quarterly “triple-witching” event, with $6.5 trillion in options tied to stocks, indexes, and ETFs set to expire. This event, which happens four times a year, involves the simultaneous expiration of stock index futures, stock options, and stock index options. The combination of these expirations often triggers increased market volatility as traders scramble to close or roll over expiring contracts.
Triple-witching days are known for unusual price movements and higher trading volumes. The last hour of trading, called the “witching hour,” sees intense activity as traders rush to adjust their portfolios before the close, leading to significant short-term market impacts.
This quarter’s figures are massive, with $4.5 trillion in index options, $710 billion in single-stock options, and $745 billion in ETF options set to expire. This sheer volume of expiring contracts can cause substantial price swings as traders reposition their holdings.
Historically, triple-witching events have brought increased volatility. For instance, in previous events, the S&P 500 saw drops of 0.2% in September, 0.5% in June, and 1% in March 2024. Tech stocks, tracked by the Invesco QQQ Trust ETF, also saw declines during these periods.
This year’s context adds further complexity. The market is already experiencing volatility due to the Federal Reserve’s recent rate cuts, and traders are awaiting the release of the November PCE inflation index, which could amplify market fluctuations.
In short, today’s triple-witching event, with $6.5 trillion in expiring options, is expected to create significant volatility. Traders and investors should be ready for price swings and heightened trading activity as the market responds.

Today, the quarterly “triple-witching” event will see approximately $6.5 trillion worth of options tied to individual stocks, indexes, and exchange-traded funds (ETFs) expire. This event, which happens four times a year, involves the simultaneous expiration of stock index futures, stock index options, and stock options. The convergence of these expirations often leads to heightened market volatility as traders close, roll over, or offset their expiring contracts.
Triple-witching can cause unusual price movements and increased trading volumes. The last hour of trading on these days, known as the “witching hour,” is particularly volatile as traders and institutional investors rush to adjust their portfolios before the market closes. This creates a unique trading environment that can have significant short-term impacts on the market.
The numbers this quarter are substantial. Approximately $4.5 trillion in index options contracts, $710 billion in single stock options, and $745 billion in ETF options are set to expire. This massive volume of expiring options can lead to significant fluctuations in market prices as traders reposition their portfolios.
Historically, triple-witching days have been associated with increased market volatility. For example, in previous triple-witching events, the S&P 500 experienced declines of 0.2% in September 2024, 0.5% in June 2024, and 1% in March 2024. Tech stocks, represented by the Invesco QQQ Trust ETF, also saw declines in the last three triple-witching occasions.
The context this year adds another layer of complexity. The market is already experiencing volatility following the Federal Reserve’s recent hawkish rate cut. Additionally, traders are bracing for the release of the November personal consumption expenditures (PCE) inflation index, which could further influence market movements.
In summary, today’s triple-witching event involving $6.5 trillion in expiring options is likely to cause significant market volatility. Traders and investors should be prepared for potential price swings and increased trading volumes as the market reacts to the expiration of these contracts.
