Lock-up shares worth 31.4 billion yuan ($5.1 billion) will become eligible for trading on China's stock markets during the next week.
A total of 1.79 billion shares of 20 companies will be tradable on the Shanghai and Shenzhen stock exchanges.
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.
These stocks will hit the market after Chinese shares realized remarkable performance in the past two weeks.
The benchmark Shanghai Composite Index surged 1.32 percent to finish at 2,937.65 points on Friday. Combined daily turnover of the two bourses in Shanghai and Shenzhen totaled 1.07 trillion yuan, setting a world record.
However, Deng Ge, spokesman for China Securities Regulatory Commission, warned of market risks at a news briefing and asked small investors to make rational decisions.
