HONG KONG, Dec 31 (Reuters) - Hong Kong shares could end 2012 off 18-month closing highs on Monday as the United States dittered on a deal that will avert a fiscal crisis, with turnover likely weak in a half day session before shutting for the New Year's Day holiday.
Last Friday, the Hang Seng Index crept up 0.2 percent to 22,666.6, its highest closing level since July 8, 2011. It is up 23 percent on the year to date after sinking 20 percent in 2011.
The China Enterprises Index of the top Chinese listings in Hong Kong rose 0.3 percent last Friday to its highest close since Aug. 5, 2011. The H-shares index is up 14.5 percent in 2012 after diving 22 percent last year.
Both Japanese and South Korean financial markets are shut on Monday for the New Year holiday. Japan will reopen on Jan. 4, while South Korea will resume trade on Jan. 2.
