After turning $100 million into $1 billion riding the technology wave of the late 1990s, Andy Kessler recounted his experiences on Wall Street and in the trenches of the hedge fund industry in the books Wall Street Meat and Running Money (and its companion volume, How We Got Here ). Though he has retired from actively managing other people's money, he remains a passionate and curious investor. Unable to keep his many opinions to himself, he contributes to the Wall Street Journal , Wired , and lots of Web sites on a variety of Wall Street and technology-related topics, and is often seen on CNBC, FOX, and CNN. He lives in Silicon Valley like all the other tech guys.
