Post# of 85479
The term quadruple witching refers to the date on which certain derivatives contracts expire simultaneously. This happens with four different types of contracts, including stock index futures, stock index options, stock options, and single stock futures. Quadruple witching dates occur four times a year on the third Friday of March, June, September, and December. Market activity on these days is typically highest during the last trading hour as traders try to move on these contracts.
