Witching days are very volatile.
Triple Witching Hour
Triple witching hour is the last hour of the stock market trading session (3:00-4:00 P.M., New York Time) on the third Friday of every March, June, September, and December. Those days are the expiration of three kinds of securities:
* Stock market index futures;
* Stock market index options;
* Stock options.
The simultaneous expirations generally increases the trading volume of options, futures and the underlying stocks, and occasionally increases volatility of prices of related securities.
On those same days in March, June, September, and December, Single-stock futures also expire, so that the final hour on those days is sometimes referred to as the quadruple witching hour.
Quadruple Witching
"Quadruple Witching" is a day on which four major contracts - stock index futures, stock index options, stock options and single stock futures - all expire. The trading on these days is typically volatile, especially during the "Quadruple Witching Hour", which is the hour before the markets close (3 p.m. to 4 p.m. ET). Quadruple witching happens on the third Friday of March, June, September, and December.
The reason that a quadruple witching day may have volatile trading conditions is that many investors want to unwind their interests in futures and options contracts prior to the contract expiration date. Stock trading increases as investors replace or repurchase existing contracts.http://web.streetauthority.com/terms...-witching.asp3
