A total of 9.68 billion non-tradable shares of 27 listed companies will become tradable after their lock-up agreements expire next week, Southwest Securities said.

On the Shanghai Stock Exchange, China Firstheavy Industries will see 4.25 billion of its non-tradable shares become eligible for trade on Monday. The market value of the shares amounts to around 12.57 billion yuan.

On the Shenzhen Stock Exchange, some 3.46 billion shares of GF Securities worth 58.06 billion yuan will be ready for trading.

The market value of next week's unlocked shares will be the second-highest seen this year, according to Zhang Gang, an analyst at Southwest Securities.
