Lock-up shares worth about 155 billion yuan (23.56 billion U.S. dollars) will become eligible for trade on China's stock market in the coming week.

Around 9.44 billion shares from 52 companies will become tradable on the Shanghai and Shenzhen stock exchanges from June 27 to July 1, according to Straight Flush, a securities information service provider.

Guotai Junan Securities, one of China's leading brokerages, will see the unlocking of 3.25 billion shares worth about 56.79 billion yuan, the largest group of shares to hit the market next week.

Under China's market rules, major shareholders of non-tradable stocks are subject to one or two years of lock-up before their shares can be traded.
