HONG KONG, Aug 17 (Reuters) - Hong Kong shares posted their steepest drop in 4-½ months to slide 3.6 percent on Monday, tracking a sharp drop on the Shanghai bourse and after U.S. consumer confidence data darkened the global economic outlook.
The benchmark Hang Seng Index finished 755.68 points lower at 20,137.65, its lowest closing level since end-July.
The China Enterprises Index, which represents top locally listed mainland Chinese stocks, was down 4.2 percent at 11,395.01, while the Shanghai Composite Index had fallen 5.8 percent to a two-month closing low. (Reporting by Parvathy Ullatil; Editing by Chris Lewis)
