Zweig's "proven methods for market forecasting and stock selection" are presented in a simplified version of the approach he uses in his Zweig Forecast newsletter calculations. Tables show how well an investor would have done by following the buy or sell signals for his Super Model, which is constructed of various "monetary" and "momentum" indicators. He also subjects his decisions to "sentiment" and "seasonal" indicators. Scan earnings reports, he advises, be flexible, have patience and discipline, set stop orders, and "don't fight the tape." The drawback, common to all such systems, is that transaction costs and taxes are ignored. Nor does Zweig's claim that his model can be accomplished on one transaction per year square with his admonition to diversify into several stocks. On balance, however, the concepts are clearly presented, and his success will probably create a demand.
