HONG KONG, Feb 28 (Reuters) - Hong Kong shares may start higher on Thursday, trimming steep losses so far this this month, after U.S. Federal Reserve Chairman Ben Bernanke reaffirmed his commitment to strong stimulus.
Bernanke, facing a congressional panel for a second day, also downplayed signs of internal divisions, saying the policy of quantitative easing has the support of a "significant majority" of top central bank officials.
Sun Hung Kai Properties and Citic Pacific are among companies expected to post corporate earnings later in the day.
On Wednesday, the Hang Seng Index edged up 0.3 percent to 22,577. The China Enterprises Index of the top Chinese listings in Hong Kong climbed 0.4 percent.
The benchmarks are down 4.9 and 8.1 percent respectively so far this month, the worst performance for both indices since May 2012.
Elsewhere in Asia, Japan's Nikkei was up 2 percent, while South Korea's KOSPI was up 1.1 percent at 0100 GMT.
