moving average(redirected from Moving average (finance))
Also found in: Dictionary, Medical.
A moving average of securities prices is an average that is recomputed regularly by adding the most recent price and dropping the oldest one.
For example, if you looked at a 365-day moving average on the morning of June 30, the most recent price would be for June 29, and the oldest one would be for June 30 of the previous year.
The next day, the most recent price would be for June 30, and the oldest one for the previous July 1.
Investors may use the moving average of an individual security over a shorter period, such as 5, 10, or 30 days, to determine a good time to buy or sell that security.
For example, you might decide that a stock that is trading above its 10-day moving average is a good buy or that it's time to sell when a stock is trading below its 10-day moving average. The longer the time span, the less volatile the average will be.
