·A number of listed companies in the tire rubber sector were suspended
On July 8, Guizhou Tire Co., Ltd. (黔 Tire A) issued a notice saying that after the application, the company's shares will be suspended from the market on the morning of July 8, 2015. It is understood that the reason for the suspension of the company is: Guizhou Tire intends to negotiate with the Guiyang Land and Mineral Resources Reserve Center on the recent land acquisition and storage after the relocation of the old factory. Guizhou Tire said that in view of the uncertainty of the matter, in order to ensure fair information disclosure, safeguard the interests of investors, and avoid significant impact on the company's share price, the company decided to suspend the suspension. It is understood that the company's stock has suffered consecutive losses since June 18, as of July 7, its closing price was 6.97 yuan / share, compared with the highest transaction price of 15.88 yuan / share on June 17, down 8.91 yuan / share The drop was 56.11%. It is noted that Qingdao Double Star and Sailong Jinyu, both of which are also in the tire sector, have also been suspended on July 8. Up to now, six tire listed companies have suspended three. In addition, Hainan Rubber and Double Arrow shares of the rubber segment are also in suspension. The same experience of several companies was the continuous decline in stock prices. Among them, Qingdao Double Star continued to fall for five consecutive trading days before the suspension. According to media reports, in the past few days, due to the stock market crash, more and more listed companies began to suspend their own "self-rescue" for various reasons. Some of them do have major issues, but there are also companies that do not know how to suspend trading, and even companies that can't find a reason for suspension, claiming to be "slow on the keyboard." According to informed sources, with the rapid increase in the number of companies in the two cities, the regulatory authorities have reminded listed companies to be “cautious†when applying for suspension of trading, “not allowing non-significant events to be suspended.†Some analysts said that these conditions show that some companies and investors have been flustered.
