From the data below, calculate the upper and lower Bollinger bands, which represent plus (or minus) two standard deviations of the 20-day simple moving average added (subtracted) from the 20-day simple moving average. If the daily price approaches or exceeds the upper Bollinger band, traders will look for a continued upward movement in the stock price. Graph the 20-day simple moving average, the upper and lower Bollinger bands, and the price of the stock. Does the graph tell you that traders expect continued strength or weakness in the stock price?
