Tomorrow.... DEFINITION of Quadruple WitchingQuadruple witching refers to a date that entails the simultaneous expiry of stock index futures, stock index options, stock options & single stock futures. While stock options contracts and index options expire on the third Friday of every month, all four asset classes expire simultaneously on the third Friday of March, June, September and December. Much of the action surrounding futures and options on quadruple witching days is focused on offsetting, closing or rolling out positions, as well as arbitrage trades, with the result being elevated volume, particularly in the last hour of trading.
