HK shares open down 0.47 pct on U.S., PICC falls

HONG KONG, Aug 20 (Reuters) - Hong Kong shares will open 0.47 percent lower on Wednesday after their worst close in a year, with sentiment further dampened by a second losing session on Wall Street as credit worries continue to haunt local stocks.

PICC Property & Casualty (2328.HK) fell 4.2 percent after the China's top non-life insurer posted a loss for the first half year as a devastating earthquake in Sichuan and an unusally harsh winter drove up catastrophe claims.

The Hang Seng Index .HSI is set to open 95.58 points lower at 20,388.79.

The China Enterprises Index .HSCE of top locally-listed mainland firms will open 0.22 percent lower at 10,690.67. (Reporting by Donny Kwok; Editing by Keiron Henderson)
