Taishan Petroleum is the largest seller of refined oil products under Sinopec. On June 20 of the first half of the year, the National Development and Reform Commission raised the ex-factory price of refined oil products in favor of it; if China's PPI and CPI data from 2008 to 2009 tend to be optimistic, the National Development and Reform Commission may once again raise the domestic refined oil ex-factory price to bring it in line with international oil prices; the adjustment of the company's actual income tax rate will raise its long-term net sales interest rate. In view of this expectation, the price-earnings ratio of 20 and 18 times the predicted performance of Taishan Petroleum for 2008 and 2009 can be assessed separately. The corresponding price range is 9.00 to 9.80 yuan, and the target median value is 9.40 yuan. The closing price of Taishan Petroleum on July 29, 2008 was 7.93 yuan. There is still room for 19% increase, giving it an “outperforming market” rating.
