A condition where a security's price heads in one direction, but then is followed quickly by a movement in the opposite direction. The origins of term is derived from the push and pull action used by lumberjacks to cut wood with a type of saw with the same name. There are two types of whipsaw patterns. The first involves an upward movement in the share price, which is then followed by a drastic downward move, which causes the share's price to fall relative to its original position. The second type involves the share price to drop for a little while, and then suddenly, the price abruptly surges towards positive gains relative to the stock's original position.
