A brand-new book by Michael Lewis, author of Liar’s Poker and Moneyball, has set the media on fire. In Flash Boys: A Wall Street Revolt, Lewis argues that not only do the liars on Wall Street play poker, but the poker game itself is completely rigged. Wall Street firms engage in a widespread practice known as high-frequency trading
(HFT). Lewis' 60 Minutes interview, features young Brad Katsuyama, the Canadian trader who helped suss out the problem.
