It is important to understand the rally and shy away from exuberance. A big part of yesterday’s rally is from the mechanics of quadruple witching. Quadruple witching consists of expiration of stock index futures, stock index options, stock options, and single stock futures. Usually such a rise tends to reverse on the following Monday. However, this typically does not happen in the Christmas week. This means that post-Christmas, risk becomes higher of another down draft.
