HK shares fall 2.5 pct; sceptical of China stimulus

HONG KONG Aug 21 (Reuters) - Hong Kong shares fell 2.5 percent on Thursday, wiping out the previous session's gains as investors grew more sceptical about speculation Beijing will launch a package to stimulate the economy and badly battered mainland Chinese markets.

Investors also stayed on the sidelines on expectations that the market may be closed on Friday after the Hong Kong observatory warned of an approaching typhoon.

The Hang Seng Index .HSI unoffcially closed 517.87 points lower at 20,413.39.

The China Enterprises Index .HSCE of top locally-listed mainland firms fell 2.4 percent.
