BEIJING - The value of lock-up shares becoming eligible for trade on China's stock market?this?week totals 54.2 billion yuan ($8.8 billion), according to data from two stock exchanges.

The volume is up by 28.9 billion yuan from the previous week. A rise in newly unlocked shares will likely put some downward pressure on the market due to the increase in stock supply.

Lock-up shares from 19 listed companies on the Shanghai and Shenzhen stock exchanges will be released to the capital market.

Home developer CFLD will see non-tradable shares worth 21.4 billion yuan become tradable on Monday, the largest amount of such shares to hit the stock 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 they are permitted to trade the shares.
