BEIJING, June 24 -- Lock-up shares worth about 33.3 billion yuan (4.9 billion U.S. dollars) will become eligible for trading on the Shanghai and Shenzhen stock exchanges in the coming week.

The amount is 52 percent more than that this week, according to Zhejiang-based Hithink RoyalFlush Information Network, a financial information provider.

Lock-up shares from 42 listed companies will become tradable from June 26 to 30, with the peak of shares unlocking of the week falling on Monday, it said.

Under China's market rules, major shareholders must wait one to two years before they are permitted to sell their shares.
