Simple moving average of 50 days for a stock is an unweighted moving average over the past 50 days. Moving averages will always exhibit a lag and the longer the period used for averaging the greater the lag will be. Because of the large amounts of data considered when calculating a long-term moving average, it takes a considerable amount of movement in the market to cause the moving average to change its course.
Using a moving average to confirm a trend in price is one of the most basic, yet effecting ways of using the indicator. Moving averages take into account what has already happened and a whole range of past events, which makes them such a good technical analysis tool for trend confirmations. Generally, a long-term moving average that is clearly on the upswing is a confirmation of a bullish trend. Conversely, a long-term moving average that is clearly on the downswing is a confirmation of a bearish trend.
