BEIJING - Lock-up shares worth nearly 31.5 billion yuan ($5.14 billion) will become eligible for trade on China's stock market next week.

About 1.57 billion shares from 33 companies will become tradable on the Shanghai and Shenzhen bourses. The value of these shares is smaller than the 80 billion yuan in shares unlocked this week, indicating weaker pressures on the faltering recovery of China's equity market.

Chinese tech company Dawning Information Industry listed on the Shanghai Stock Exchange will see non-tradable shares worth around 8.77 billion yuan become tradable on Friday, the largest amount to hit the market.

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.
