HONG KONG, Aug 5 (Reuters) -By 0345 GMT on Wednesday, the benchmark Hang Seng Index <.HSI> was down 0.1 percent at 20,774.08.
The China Enterprises Index, which represents top locally listed mainland Chinese stocks, was 0.6 percent lower at 12,147.28.
Here are some of the stocks on the move-
* Asia's No.3 air carrier Cathay Pacific Airways jumped 2.5 percent to HK$12.96 ahead of its first-half earnings announcement due later on Wednesday with analysts expecting the airline to claw its way back into the black after reporting a loss for last year.
HSBC said it expected Cathay to report a HK$400 million profit for the first six months of 2009, compared with a HK$663 million loss a year earlier, helped by lower fuel costs and fuel hedging gains.
* Hong Kong Aircraft Engineering Co Ltd (HAECO) slid 7.7 percent after posting a 27 percent drop in first-half profit, reflecting increasingly difficult trading conditions for the company as airlines cut capacity and expenditure in response to falling demand.
The company said it expected business activity in the second half of 2009 to be substantially weaker than in the first as airlines continued to reduce services and expenditure.
* China Railway Group soared 6.9 percent to HK$7.55 on Wednesday after Goldman Sachs raised its rating on the stock as it expects railway investments in China to remain strong for the rest of 2009. The stock scaled a 14-month high of HK$7.76 earlier.
Goldman Sachs upgraded the stock to "buy" from "neutral" and nearly doubled its traget price to HK$10.35.
China Railway Group said over the weekend it would consider a US$7.5 billion contract as contractor for a railway design and construction project in Venezuela.
* China Communications Construction climbed 2 percent to HK$10.38 after Goldman Sachs raised its rating on the stock to "neutral" from "sell" on the back of government-supported investment and the company's efforts to diversify its business to offset weakness in its core markets.
Goldman Sachs nearly doubled its target price on China's top builder of highways and ports to HK$11.61. (Reporting by Parvathy Ullatil; Editing by Chris Lewis)
