Alert: Friday is a Quadruple Witching Trading Day

There are expirations tomorrow on four types of standardized contracts: stock options, stock index options, stock index futures, and single stock futures.

Sometimes, not always, this can result in great volatility and wide price swings. Often this volatility doesn't kick in until the last hour. One hundred point swings may not occur, but they should not surprise, if they do occur.
