HONG KONG, Aug 24 (Reuters) - Hong Kong shares could start lower on Friday after comments from the St. Louis Federal Reserve President James Bullard crimped expectations for quick stimulus action from the Fed, setting the Hang Seng Index on its way to ending a second week barely hanged.
Corporate earnings will stay a focus point. Aluminum Corporation of China (Chalco), China Construction Bank , Haitong Securities and Yanzhou Coal Mining are among companies expected to post first-half earnings later in the day.
On Thursday, the Hang Seng Index closed up 1.2 percent at 20,132.2, bouncing off a three-week low produced on Wednesday and returning above the 20,000 level that has supported the benchmark for all but two sessions in almost three weeks.
The benchmark is now up 0.1 percent this week to date.
Elsewhere in Asia, Japan's Nikkei was down 1.3 percent, while South Korea's KOSPI was down 1.2 percent at 0047 GMT.
