I'm often asked about books, particularly now with regard to the journal thread I've been sponsoring (below), and I've always put Mamis' trilogy at the top of the list: The Nature of Risk, When to Buy, and How to Sell. Mamis doesn't have much use for mathematically-derived indicators like RSI or CCI. Rather he looks at the same sorts of "indicators" that Zweig does, such as short-selling activity, bull and bear percentages, and the only one that I follow, the differential between volume of advancers and of decliners. All of which is a preface to the following interview conducted in January, in which Mamis states that most of the indicators he used to rely on are of little use to him due to changes in market psychology and dynamics. Therefore, for those to whom I've recommended Mamis' books and for Mamis fans everywhere, the interview: http://www.weedenco.com/welling/archive/li/v06i01lilogo.asp Note that this does NOT mean that I no longer recommend Mamis. The point is that an understanding of price action and volume action and the relationship between the two are more important than ever. That and an understanding of market psychology. Why did I start a separate thread for this? Because I think it's important enough.
