HONG KONG, Dec 24 (Reuters) - Hong Kong shares could start the week lower on Monday, tracking Wall Street's losses on U.S. fiscal concerns that are likely to be exacerbated by turnover weakened by the Christmas holiday.
Hong Kong financial markets will shut at noon on Monday and reopen on Thursday.
Last Friday, the Hang Seng Index shed 0.7 percent, its worst daily loss since Dec. 3, to knock the benchmark off a near 17-month high to 22,506.3. It slipped 0.4 percent last week, its first weekly loss in five.
Elsewhere in Asia, South Korea's KOSPI was flat at 0059 GMT, while Japan's financial markets are closed for holidays.
