content: Very simply this system is all about following the trend and followin interest rates.In 2000, when Allen Greenspan was raising interest rates that identified a sell signal. When interest rates go up, stocks go down.Zwieg is not a "buy and hold" man. His system works. I've been following it since 1989 when I bought this book along with Winning with New IRAs and Wealth without Risk. To wit I caught the big stock market boom in late 1990 through 1991 and again in 1995-1996 and in 1998-2000.I also missed the selloffs in late 1989-1990, 1994-1995, and 2000.The Zweig system works. Try it, you'll love it.
