200-day moving average

200-day moving average

A technical indicator compiled as a statistical series of a security's closing prices throughout 200 consecutive trading days. A 200-day moving average is designed to discover changes in a trend. Generally, a moving average is superimposed on a stock's line chart. If the stock price penetrates the moving average on the upside after a downward trend, the penetration is a signal to buy. But if the stock price penetrates the moving average on the downside following an upward trend, the penetration is a bearish sign.
