Moving average

moving average
A series of successive averages of a defined number of variables. As each new variable is included in calculating the average, the last variable of the series is deleted. Suppose a stock's price at the end of each of the last 6 months is $40, $44, $50, $48, $50, and $52. The 4-month moving average in the fifth month is: ($44 + $50 + $48 + $50)/4, or $48. At the end of the sixth month, the 4-month moving average is ($50 + $48 + $50 + $52)/4, or $50. Technical analysts frequently use moving averages to discover trends in stock prices. See also 200-day moving average.
