HONG KONG, Aug 25 (Reuters) - Hong Kong shares opened 1.4 percent lower on Tuesday, weighed down mainly by disappointment over Chinese aluminium producer Chalco's interim loss, while the market sought more positive data elsewhere.
Investors will be watching the trend in U.S. housing data, due for release later in the day.
The benchmark Hang Seng Index opened down 290.23 points at 20,246.34.
Chalco, which posted its third consecutive quarterly loss on Monday on weak demand and low prices for the metal, dropped 3.6 percent.
The China Enterprises Index, which represents top locally listed mainland Chinese stocks, opened down 1.9 percent at 11,478.53. (Reporting by Nerilyn Tenorio; Editing by Chris Lewis)
