The problem with long termer moving averages ie 20 and 50 day etc ... is that when a change of direction does come a long it takes a long time for those averages to register that something has changed... Wait for them to swing up and you will miss most of the short term % gain. Longer term averages are usually used by the "set and forget" brigade especially when you get up to 150 day and 200 day averages ...most often used on Indicies and Blue chips... not much for spec'es IMHO
