About Brad Katsuyama
Referred to as the most powerful person on the market floor by Michael Lewis, Brad Katsuyama is the subject of Lewis’ latest best-seller, Flash Boys: A Wall Street Revolt—one of the most provocative books ever to hit the financial market. The story reveals how the much talked about practice of computerized high-frequency trading (HFT) has allowed certain Wall Street players to work the stock market to their advantage. As the former Head of Electronic Sales & Trading at RBC, Brad Katsuyama noticed the seemingly small discrepancies (often fractions of a penny) that, when compounded, were costing his clients and many other major market players millions of dollars. Brad uncovered the inner-workings of this computerized trading system, and was one of the first to draw attention to a practice that—as Lewis puts it—is “rigging the market.” Brad helped devise a plan to identify and correct the effects of HFT tactics with the creation of IEX, an upstart stock trading venue designed to institutionalize fairness through the use of technology.
