Hong Kong shares were flat on Friday as bargain-hunting in heavyweights such as HSBC was restrained by a weak market debut for Agricultural Bank of China and fears of slowing economic growth in China, according to Reuters. The benchmark Hang Seng Index ended down 0.03 percent or 5.46 points at 20,259,16. The China Enterprises Index of top locally listed mainland Chinese stocks closed down 0.07 percent at 11,419.62. Shares in Agricultural Bank of China edged up 2.2 percent from its HK$3.20 issue price.
