After China High Speed Transmission (00658-HK) was added to Goldman Sachs's buying list in January last year, Goldman Sachs still called to buy it in June, but today, this trend has weakened. Goldman Sachs has downgraded its rating to neutral, and the target price remains at 7.7 yuan. Goldman Sachs no longer insists on buying ratings because since the beginning of last year, the stock price has risen 58.8%, falling 20.9% compared to the Hang Seng Index period. Faced with this backlash, Goldman Sachs said it will no longer publish research reports on China's high-speed transmission in the future! Today's stock price trend of China High Speed Transmission was not affected by the report. The stock price was quoted at 8,1 yuan, which is currently the low for today. It is currently at a high of 8.73 yuan. It was reported at 14:04 at 8.68 yuan, up 4%. The number of shares traded was 4.55 million shares, resulting in an approximate amount of 39.01 million yuan. There was a clear decrease in the number of shares traded in this stock at the beginning of this month. On the first 2 trading days of this month, the number of shares traded was 8, but recently dropped to millions of shares. Friends in the securities industry said that previously, Fengsheng Holdings (00607-HK) proposed to buy all of China High Speed Transmission in the form of a stock exchange, and finally obtain a controlling interest in China High Speed Transmission. There should be hope for this. However, Goldman Sachs has a different opinion. The bank has this comment on the deal. The synergy brought about by the share exchange between China Transmission and Fengsheng Holdings is limited because Fengsheng Holdings' experience in managing the renewable energy business is limited.
