Index provider MSCI will announce on Tuesday whether it will include mainland Chinese stocks in the company’s global and emerging-market indices, a decision that comes as other providers appear to be shifting toward an embrace of the so-called A-shares, The Wall Street Journal reported. Rival FTSE Group has already inaugurated transitional indices for emerging markets to include the shares, while competitor S&P Dow Jones has said it will likely add Chinese shares to its indices this September. The firms are buying into a volatile market–the Shanghai Composite Index alone has lost or gained more than 3% in one session more than ten times this year.
