Ned Davis is one of the most respected analyst on the street commanding huge following amongst institutional clients. Many years ago his firm published the above book and it was updated in 2000, just prior to 2000 market top. There is a reason the book is so much in demand. It details the methodology used by the firm to do top down analysis. It details various macro economics, sentiment, technical, financial, and inter market indicators used by his firm to arrive at timing model. If you want to become real "Big Picture" macro analyst, this book is a must read.
Now more important than the excellent macro indicators and their interpretation is their equity selection model. "Price Momentum Based Equity Selection (The General Theory of Relativity)", that is the title of the chapter which details the equity selection method.
The equity selection method uses one year relative strength. Buys the top ranked 5% stock with strongest momentum and holds them until they fall below the top 10% in momentum rank.
Momentum based systems work in most market environment that is why an IBD 200 kind of triple momentum based (price, sector, and earnings), works.
