Chen Hua, a researcher in the new energy industry of CICC, recently recommended Yu Diamond (300064).
 The research report pointed out that Yu Diamond's net profit for the first half of the year was 66 million yuan, an increase of 82%. The main business diamond continued to expand production, and the supply exceeded demand, and the gross profit margin increased. In addition, diamond wire products have been produced and actively seek customer recognition. Whether the technology and process can be widely promoted in China depends on whether the quality of domestic products is qualified, and whether wafer companies can master the corresponding cutting process. In addition, the price of diamond wire needs to be less than 1.3 yuan / meter in order to be economical. The diamond wire price of Yu Diamond is expected to be no more than 1 yuan / meter, so as long as the quality of its products is qualified, it is accessible in large-scale promotion in China. A conservative estimate for next year will achieve an income of 65 million yuan. CICC forecasts that the company's 2011-2013 earnings per share will be 0.5, 0.82 and 1.12 yuan respectively, based on the judgment that the technical replacement of diamond wire in the field of silicon wafer cutting will accelerate in the second half of the year, maintaining recommendations. As of 9:40 on August 22, the stock quoted 21.20 yuan, a year-to-date increase of 15.8% (after reinstatement).
