Comparative chart results are based on the percentage price change for the securities or indexes for the Time Period specified. All percentage returns are calculated based on simple capital appreciation. Volume numbers and moving averages are shown only for the security or index entered in the first text box in the Chart Generator. A 10-day moving average, for example, is the average closing price of the security for the past 10 trading days divided by 10, plotted on a chart. As many as two moving averages can be plotted on the same chart, along with its security or index, enabling investors to discern the price trend.
Intersection points are also important when viewing moving averages.
If a stock crosses its 50-day moving average trending downward, for example, this could be interpreted as a signal to sell. Similarly, if the stock crosses its 50-day moving average trending upward, this could be interpreted as a signal to buy. The moving average shown will depend upon the Time Period you select. Intraday charts cannot contain moving averages. Or simply select None.
