HONG KONG, Feb 26 (Reuters) - Hong Kong shares sank to their lowest close this year on Tuesday, with financials and other growth-sensitive sectors the bigger losers as Italy's political uncertainty made investors wary of risky assets.
The mainland markets shed midday gains and closed at their lowest in more than a month, with the property, premium alcohol and railway sectors hurt by local media reports of policy rumblings before next week's annual parliamentary meetings.
The Hang Seng Index fell 1.3 percent to 22,519.7, its lowest closing since Dec. 21. The China Enterprises Index of the top Chinese listings in Hong Kong slid 2 percent.

"This is not a good entry point for those who have missed the rally at the start of the year," said Hong Hao, Bank of Communication International's chief strategist.
He added that uncertainties over post-election Italy, the continuation of U.S. quantitative easing and Japan's new central bank governor will likely rise and could roil markets in coming weeks.
Investors will also be watching comments from Federal Reserve Chairman Ben Bernanke at a two-day congressional testimony starting later on Tuesday that will subject its bond-buying programme to tough scrutiny and gauge his confidence in the resilience of the U.S. economy.
Hong said expectations for China's parliamentary meetings "are also too high. The meetings will be about the big picture and longer-term goals. Specific details are highly unlikely."
The annual Chinese People's Political Consultative Conference and National People's Congress, where Xi Jinping is expected to be confirmed as China's president, start in Beijing on March 3 and 5, respectively.

NO CHINA TIGHTENING, YET

China Vanke sank 1.7 percent in Shenzhen and has now slumped 14.6 percent from a Jan. 30 peak on fears of further tightening in the sector after recent home-price rises.
