Hong Kong shares rebounded by more than 2 per cent in morning trading Wednesday on the back of strong overnight gains on Wall Street, according to dpa. The Hang Seng Index ended the morning session up 516.92 points, or 2.25 per cent, at 23,512.27 points. Turnover was 51.9 billion Hong Kong dollars. The rebound, which followed the index's worst week for seven years last week, comes after the US Federal Reserve announced a series of moves to ease the credit crunch, giving Wall Street a major boost.
