IntercontinentalExchange completes its acquisition of NYSE Euronext on Wednesday, and CEO Jeffrey Sprecher faces an integration of herculean scale. Sprecher says he plans to shift the exchange operator's focus away from high-frequency traders and toward individuals. "Everything we do on the NYSE should be focused on: Are we making it a better environment for individual investors and people who manage individual investors' retirement accounts?" Sprecher said. The takeover gives Sprecher access to a long-desired line of business: interest-rate derivatives.
