Triple Witching

Fancy Way to Say: Mass Derivative (i.e. options, futures) Expiration Four times a year, on the third Friday of the quarter ending month (March, June, September, December) three different types of derivatives related to stocks expire: Options on Individual Stocks; Options on Stock Index; Futures; Stock Index Futures. The 'mass' expiration can cause wild gyrations and false moves in prices as contracts are covered, rolled over, etc.
