Ten private equity firms have been selected as market makers in China's over the counter bourses. The move is widely expected to boost the trading volume of the OTC market.

Each of the 10 PE firms has funds under management of over 2 billion yuan, with big names including Fosun Capital and Shenzhen Capital.

Only a few securities companies were previously allowed to provide market making services in the OTC trading exchanges.

Experts say the inclusion of the PE firms will boost underwriting and trading, and help stocks set reasonable price ranges.
