"How I 6X-ed my wife's 401K in 1 year" At the peak of the dot-com boom, a former hedge fund manager put all $20,000 of his wife's 401k into shares of just ONE stock. Everyone on Wall Street said he was crazy. But a year later, that $20,000 in his wife's account was worth $120,000. Today, he says: "If you thought the dot-com mania was intense, what's about to happen in the coming weeks could be even crazier and could open up a new window of opportunity for 500%-plus gains."
