China's clampdown on data spreads to real-time stock information

HONG KONG -- Three major exchanges in China plan to stop disclosing real-time trading volume data starting in mid-May, claiming the move is aimed at taming market volatility, but it has also raised concerns among investors on data transparency.

Real-time data on the buying, selling and total turnover of A-shares in Shenzhen and Shanghai by foreign investors will no longer be available to the public market during trading hours. The new rules will apply to a key trading link between Hong Kong and the mainland that has been in place since 2014.
