Occurring just 4 times per year, the simultaneous expiration of stock options, stock index futures, and stock index option contracts on the same day is known as "Triple" what?

So-called "Triple Witching" happens on the third Friday of March, June, September, and December, and can cause some odd fluctuations in equities and irregular trading; hence, the term "witching".
