S&P and HKEx go head to head with Hang Seng

HSI Services, the index vending arm of Hang Sang Bank, is making another attempt at providing the market with a comprehensive series of Hong Kong stock indices adjusted for free float. The launch is designed to stymie the onslaught of a partnership between American indexing behemoth Standard & Poor's and the Hong Kong Stock Exchange (HKEx), which are due to launch the first of their indices in March.
