Antoine Shagoury
Chief Operating Officer
London Stock
Exchange Group

London Stock Exchange Group completed its flagship exchange's epic migration from an aging trading system, TradElect, onto a sleek new platform engineered by its Colombo, Sri Lanka–based subsidiary, MillenniumIT, in February 2011. With that transition, and the errors that plagued it, behind him — and recently promoted to COO from chief information officer — Antoine Shagoury has moved on to a new set of projects as LSE Group integrates acquisitions and focuses on its data and clearing businesses. "We see a tremendous amount of opportunity within the group to enhance our portfolio, focus on new products and grow organically," says the 42-year-old, a former American Stock Exchange CIO who joined LSE in 2010. LSE in December bought the remaining 50 percent of London-based index provider FTSE International that it didn't already own from Pearson for £450 million ($695 million). Shagoury says his team is "looking closely at different ways of disseminating and calculating the indices" and further enriching the group's market data offerings. LSE will join the posttrade elite when it completes its purchase of a majority stake in LCH.Clearnet Group, expected in the fourth quarter.
