Triple witching hour

The four times a year that the S&P futures contract expires at the same time as the S&P 100 index option contract and option contracts on individual stocks. It is the last trading hour on the third Friday of March, June, September, and December, when stock options, futures on stock indexes, and options on these futures expire concurrently. Massive trades in index futures, options, and underlying stock by hedge strategists and arbitrageurs cause abnormal activity (noise) and volatility.

Triple Witching

The last hour of trade on an exchange on the third Friday of March, June, September, and December. It is the time of expiration for three types of standardized contracts: stock options, stock index options, and stock index futures. Investors often unwind their positions on these contracts during or immediately before triple witching hour, which leads to increased trading volume on those hours. See also: Quadruple witching day.
