Triple-witching is a term traders and investors must familiarize themselves with, given it can significantly influence the stock market. This term refers to the moment when stock options, index options, and index futures expire simultaneously - an event which happens four times a year, specifically on the third Fridays of March, June, September, and December. Triple-witching often leads to heightened trading activity and market volatility.
The last triple-witching for this year occurred shortly after one of the most severe stock sell-offs in months. The volatile season followed a surprising profit surge in November and early December sparked by President Donald Trump's reappearance in power.
Furthermore, the latest triple-witching coincided with a shuffle in the major indexes like S&P 500 and Nasdaq 100. Interestingly, this saw Workday, a software firm, and asset management titan Apollo Global Management replace tech heavyweight Qorvo and engineering behemoth Amentum Holdings in the S&P 500. Palantir Technologies, Bitcoin-backer MicroStrategy, and taser-producer Axon Enterprise also replaced biotech Illumina, AI server creator Super Micro Computer, and vaccination giant Moderna in the Nasdaq 100.
Triple-witching days may induce abnormal trading volumes and unexpected price fluctuations for certain stocks. However, long-term investors need not panic as these events seldom affect market sentiment - any volatility triggered by the options and futures activity is typically short-lived. As for active market players, the final hour of triple-witching can sometimes create a less fluid market for particular securities, presenting opportunities to engage in arbitrage by trading the same security at varying prices across multiple markets.
