      When the selling pressure subsides, the stock is likely to bounceback. Sometimes size sellers (buyers) will pause and allow the stock toretrace. Without the pause, the seller (buyer) will place too muchcontinuous pressure on a stock and drive the price down (up) considerably.To avoid getting a lower dollar cost average price, the seller (buyer) willtake a breather and let the action of market participants retrace themovement in the stock that was caused by the onslaught of selling (buying)pressure. This is a great opportunity to make an eighth, a quarter, or ahalf on the long (short) side, depending upon the volatility in the stockand the extent to which the selling (buying) pressure pushed the stockprice down (up).
