Quadruple witching day: Brace for market volatility

Dec. 19, 2025 6:23 AM ET
By: Jessica Kuruthukulangara, SA News Editor

Expect market volatility on Friday on account of quadruple witching - meaning stock index futures, stock index options, stock options, and single stock futures will expire simultaneously.

While December options expirations are usually the biggest of the year, Friday could see the largest options expiration on record, CNBC reported, citing Goldman Sachs analysts.

More than $7.1T in notional options exposure is set to expire on Friday, including about $5T tied to the S&P 500 index ( SP500) and $880B linked to single stocks.

The options that are set to expire represent notional exposure equal to about 10.2% of the Russell 3000's total market capitalization.

Meanwhile, certain stock prices can get pulled toward heavily traded strike levels as traders adjust their hedges, a phenomenon known as a "pin."

According to Goldman, stocks with options expiring on Friday that represent a large share of their typical daily trading volume and could be prone to "pinning" include GeneDx ( WGS), BILL Holdings ( BILL), Avis Budget ( CAR) and GameStop ( GME).
