IntercontinentalExchange CEO Jeffrey Sprecher said it's important for the New York Stock Exchange, which ICE is in the process of purchasing as a part of NYSE Euronext, to continue to maintain its person-to-person trading floor. "Markets need a human touch," Sprecher said. "When there's a problem in the market, business goes back to the floor. What we're buying in the New York Stock Exchange is the place where everyone goes in times of trouble or times when the market is wanting real certainty. That's the one you want to own."
