Shanghai's main index erase earlier gains, turn negative on profit-taking

SHANGHAI (Reuters) - Main stock indexes in the Shanghai Stock Exchange erased earlier gains and turned negative in about 10 minutes into trading on Monday as profit-taking set in.

Share prices had initially rose over 1 per cent on the launch of a landmark trading scheme linking the Shanghai and Hong Kong stock exchanges.

Both the CSI300 index of top Chinese shares and the Shanghai Composite Index lost about 0.2 per cent around 0140 GMT, having also jumped in the run-up to the launch.
