Moving average crossover of a 15-day exponential close-price MA (red) crossing over a 50-day exponential close-price MA (yellow) In the statistics of time series, and in particular the stock market technical analysis, a moving-average crossover occurs when, on plotting two moving averages each based on different degrees of smoothing, the traces of these moving averages cross.
In statistics, a moving average (rolling average or running average or moving mean [1] or rolling mean) is a calculation to analyze data points by creating a series of averages of different selections of the full data set. Variations include: simple, cumulative, or weighted forms. Mathematically, a moving average is a type of convolution.
In time series analysis, the moving-average model (MA model), also known as moving-average process, is a common approach for modeling univariate time series. [ 1 ] [ 2 ] The moving-average model specifies that the output variable is cross-correlated with a non-identical to itself random-variable.
AppFolio (APPF) could be a stock to avoid from a technical perspective, as the firm is seeing unfavorable trends on the moving average crossover front
The formula for the MACD line is based on two exponential moving averages of the close prices, usually with the periods of 12 and 26: [5] M A C D l i n e = E M A 12 − E M A 26 {\displaystyle MACD~line=EMA_{12}-EMA_{26}}
