In the past week, the three major A-share indexes reversed last week's surge and closed down collectively. Within a week, the Shanghai Composite Index fell 2.41%, the Shenzhen Composite Index fell 2.79%, and the gem Index fell 1.2% a week.

In terms of individual stocks, a total of 13 stocks have risen more than 40% this week after excluding new and sub-new shares. The biggest increase was in clear water, with a cumulative increase of 81.62%. Guangyu Development rose 61.08% to rank second, while Daijin heavy Industry, six countries Chemical Industry, Yunda shares, Hengrun shares and other stocks all rose more than 50%.

From the decline list, Tianyin Holdings fell 39.78% to the top, while the World Bank, UBS New Materials, Shanghai Ailu, Longhua Technology, Mona Lisa, Jincheng Pharmaceutical, ST Western region, Sinotruk and so on all fell by more than 20%.

　　Tianyin Holdings fell four times in a row, or is there information leakage?

Recently, Tianyin Holdings is definitely the focus of the public opinion field of the capital market.

First, the share price soared for no reason, rising by 274.86% in less than two months, then the company issued a controversial and ambiguous acquisition announcement, followed by regulatory inquiries, and finally the company released a lower-than-expected result, and the share price fell by the limit for four consecutive times.

Although the company said it had not leaked the news in advance, there was still a steady stream of doubts in the whole public opinion field. It does not seem so surprising that Tianyin Holdings, which has fallen by the daily limit of four days in a week, occupies the first place on the list of declines.

However, Apple Inc's new phone went on sale today, coupled with Tianyin Holdings' previous announcement that it plans to participate in the joint acquisition of Tian long Mobile's mobile phone sub-brand, as the domestic smart terminal distribution leader, its follow-up performance may gradually return to normal.

　　Qingyuan soared 148.68% on the 7th. Will trading be suspended for inspection from next week?

As the first of the gains, Clearwater's overall rise this week can be said to be overwhelming. First won two "20CM" limit, and then still rising, rising in the volatility all the way up, the latest market value has reached 5.6 billion yuan, has doubled from last week.

With regard to the sharp rise in clean water, the "opinions on deepening the Reform of the Ecological Protection compensation system" issued by the General Office of the CPC Central Committee and the General Office of the State Council is undoubtedly a favorable policy.

However, many investors also said that Clearwater is ostensibly an environmental protection unit, but what is really valuable is to return the waste products disposed of by the company. Lithium hexafluorophosphate, which has recently been heated in the market, is not without phosphorus trichloride, chloromethane and other raw materials involved in Qingshui. Coupled with the recent rise in the price of the chemical industry, fresh water has suddenly turned around by collecting waste products.

However, for Clearwater, which topped the list, the surge in share prices may be a blessing and a blessing.

On September 17, Clearwater announced that in view of the recent serious abnormal fluctuations in the company's share price, the company will verify the serious abnormal fluctuations in stock trading, suspend trading from the opening of the market on September 22, and resume trading after the disclosure of the verification announcement.

At the same time, the Shenzhen Stock Exchange also said that the recent abnormal growth of "clear water", "Zhongqingbao" to focus on monitoring, and take timely regulatory measures.
