Using The Shadow
Some technical analysts believe a tall or long shadow means the stock will turn or reverse. Some believe a short or lower shadow means a price rise is coming. In other words, a tall upper shadow means a downturn is coming, while a tall lower shadow means a rise is coming. A tall upper shadow occurs when the price moves during the period, but goes back down, which is a bearish signal. A tall lower shadow forms when bears push the price down, but bulls pull it back up, which leaves a long line or shadow. This is considered a bullish signal.
