China’s national pension fund has increased its A-share purchases as part of efforts to help stabilise the market, while cutting H-share holdings which have begun trading at a premium to their mainland-listed counterparts.

Based on the third-quarter earnings reports by all mainland-listed firms, the National Social Security Fund (NSSF) held A shares worth 50.4 billion yuan (HK$ 62.5 billion) at the end of September, 2.5 billion yuan more than its holding at the end of June, according to the state-owned Securities Times.
