Individual stocks can go up or down, sometimes with attention-grabbing swings.
Zhengzhou Baiwen, a major retailer in Henan province, was once a valuable stock that became almost worthless in a relatively short period of time, and that's the kind of move that grabs the attention of regulators. The official emphasized that the ongoing work of asset restructure does not imply that the company is somehow exempt from the probe investigating possible violation of law. He added that the CSRC is pooling efforts to examine Baiwen's alleged violations of laws supposed to have occurred from the time the company listed on the stock market. The CSRC will punish anyone implicated in any confirmed violation and make the details of such cases public, the official said. Any violations discovered that happen to fall under the jurisdiction of other authorities will be turned over to the department concerned.
