Robert Prechter was named guru of the decade by FNN (the CNBC forerunner) in about 1989. Prechter made excellent market calls from the late 1970’s through 1987.
Since then, he has been consistently wrong. Wrong for over 30 years (3 decades!). Not just wrong on the stock market, passionately wrong. Now, there have been 4 very significant bear markets from 1988 onward, and because Prechter = bearish, he was bearish in front of them. But he has been bearish for over 30 years, and missed all (most all?) of the stock market advance. He and his idiot puppet Hochberg are not just terrible markets analysts, to the extent they teach about markets, they teach bad market lessons.
