ST shares plunge on delisting rules

Shares carrying the "special treatment" tag sank on Monday as the central authorities clarified rules for delisting aimed at improving market compliance.

Impacted by the latest stringent rules targeting delisting, ST shares, such as Harbin Gong Da High-Tech Enterprise Development, fell by the 5 percent daily limit soon after the market opened on Monday.

The plunge was in sharp contrast to the situation a week ago, when 53 of the 78 shares with ST tags surged by the daily limit last Monday.
