HK shares open firm, but HSBC weighs on blue chips

(Updates to open)

HONG KONG, Nov 28 (Reuters) - Hong Kong blue chips rebounded
0.4 percent on Wednesday, boosted by sharp gains in U.S. stocks,
but HSBC Holdings plc (0005.HK) was down at the open amid nagging
worries about possible further consequences of risky credit.

The benchmark Hang Seng Index .HSI opened at 27,315.93.

The China Enterprises index of H shares .HSCE, or Hong
Kong-listed shares in mainland companies, opened up 0.8 percent
at 16,415.12.
