Closing prices are used for these moving averages. Simple_cum_strategy_asset_relative_returns = np.exp(simple_cum_strategy_asset_log_returns) - 1 MACD Line: (12-day EMA - 26-day EMA) Signal Line: 9-day EMA of MACD Line MACD Histogram: MACD Line - Signal Line The MACD line is the 12-day Exponential Moving Average (EMA) less the 26-day EMA. # Transform the cumulative log returns to relative returns Simple_cum_strategy_asset_log_returns = simple_strategy_asset_log_returns.cumsum() # Get the cumulative log-returns per asset Simple_strategy_asset_log_returns = simple_weights_matrix * asset_log_returns # Get the buy-and-hold strategy log returns per asset Simple_weights_matrix = pd.DataFrame(1/3, index = data.index, columns=lumns) # Define the weights matrix for the simple buy-and-hold strategy What does EMA stand for in Stock Get the top EMA abbreviation related to Stock. SMA assigns equal weightage to all the data points(read stock. You must be familiar with SMA(simple moving average). The exponential moving average (EMA) is a weighted average of the last n prices, where the weighting decreases exponentially with each previous price/period. To get all the strategy log-returns for all days, one needs simply to multiply the strategy positions with the asset log-returns. EMA Stock Abbreviation Meaning Stock EMA abbreviation meaning defined here. EMA stands for exponential moving average. ![]() How much is this lag $L$? For a SMA moving average calculated using $M$ days, the lag is roughly $\frac$. 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.
