As these contracts come to a close, traders and investors might decide to close out, renew, or exercise their positions. Triple witching is the simultaneous expiration of stock options, stock index futures, and stock index options contracts, all on the same trading day. This happens four times a year, on the third Friday of March, June, September, and December. The expected expiration date for the three might increase trading volume and cause unusual price changes in the underlying assets. When these three types of contracts expire simultaneously, it creates a flurry of trading activity as investors close out existing positions, roll over contracts, or establish new ones.<\/p>\n<\/p>\n
