BEIJING -- About 2.04 billion non-tradable A-shares of 22 listed companies will be unlocked this week and become available for trading starting Monday, according to the Shanghai and Shenzhen stock exchanges.

The market value of the unlocked shares stood at 19.29 billion yuan ($2.97 billion) on Friday last week.

The volume of this week's unlocked shares this week remains at a fairly low level, down 6.71 percent from last week, while the unlocked shares' market value fell 42.83 percent week-on-week, said Zhang Gang, chief strategic analyst for Southwest Securities.

The relatively low capitalization of unlocked shares means less liquidity pressure on the secondary stock market this week, analysts said.

According to the Shanghai and Shenzhen stock exchanges, 158.57 billion yuan in locked shares will become tradable this month.
