How did John W. Henry quietly become rich enough to buy the Boston Red Sox? How have traders like Keith Campbell, Bill Dunn, Jerry Parker, and Salem Abraham consistently generated immense wealth in bull and bear markets? The key is trend following -- the only strategy proven to consistently make money. Michael Covel reveals the "underground" network of little-known traders and hedge fund managers who've been following trend for decades. He introduces its fundamental concepts and techniques, showing why market prices contain all the information investors need, and how to understand price movements well enough to profit from them. Using 100 pages of easy-to-understand charts from top trend followers, Covel proves the strategy works -- and shows why only a technical system based on following price trends can win over the long term. Covel presents more than a decade's worth of data:  even more backtested trend following results.  Covel thoroughly debunks misinformation and failed advice. This timely book capitalizes on today's intense volatility and uncertainty to give investors what they're desperately searching for: a strategy that really works.
