Hong Kong - Hong Kong shares slumped 4.7 per cent Monday following weak results at some Chinese companies and wider concerns about the US economy.

The benchmark Hang Seng index closed at 13,456.33 points, down 663.17 points after its biggest one-day drop for three weeks. Turnover was almost 51.53 billion Hong Kong dollars (6.6 billion dollars).

Analysts said investor sentiment had been adversely affected by results from several top Chinese companies.

Chalco, China's leading aluminium producer, saw its share price drop 12 per cent after it reported a 99 per cent drop in earnings to 9.2 million Yuan (1.35 million dollars) last year, down from 10.75 billion yuan in 2007. Shares in China Construction Bank dropped 9.6 per cent.

Analysts said stockholders were also worried about the health of the US economy after leading auto maker General Motors said it wanted an additional 16.4 billion dollars from the Obama administration, on top of 13.4 billion dollars it has already received. (dpa)
