SMACD - Standardised MACD
Standardised MACD - this uses the MACD indicator, but expressed as a percentage of Close price. This allows for the relative comparison between stocks which have different absolute values. MACD will give a high value to a high priced stock, whereas SMACD will represent stock performance in a standardised format, relative to the closing price of the stock. It effect it represents the MACD as a percentage of share price. An added advantage of SMACD over MACD is that since the indicator is relative to the price, later values are not inflated (assuming rising trend). Thus the scale is not linear, rather it more like a log scale, offering a truer picture of growth over time. It is for this reason the SMACD lines may slightly differ from MACD, but it is a more valid representation in my view. The difference is minor. (Developed by Des Bleakley - Melbourne)
