This is a list of AMEX stocks and shares which are trading above 122 day moving averages. # Define the weights matrix for the simple buy-and-hold strategy List of Stocks above 122 day Moving average. To get all the strategy log-returns for all days, one needs simply to multiply the strategy positions with the asset log-returns. EMA) of window length N from the shorter EMA of window length M, where the. How much is this lag $L$? For a SMA moving average calculated using $M$ days, the lag is roughly $\frac$. This paper revisits the performance of the two trading rules. However, this comes at a cost: SMA timeseries lag the original price timeseries, which means that changes in the trend are only seen with a delay (lag) of $L$ days.
It is straightforward to observe that SMA timeseries are much less noisy than the original price timeseries.
