Most Asian markets were down in the morning as investors remained cautious of the US election outcome and eurozone concerns returned with Greek bailout issues.

Japan's Nikkei traded 0.35 percent or 31.15 points lower to 8976.29 at 02:20 GMT, while South Korea's KOSPI was up 0.19 percent or 3.71 points to 1911.93.

China's Shanghai Composite Index slid 0.36 percent or 7.62 points to 2106.41. Hong Kong's Hang Seng was down 0.26 percent or 57.82 points to 21948.58.

Analysts suggest that a win for Republican contender Mitt Romney is perceived as more positive for the equity markets.

"Markets will be looking forward to the other side of the elections when the uncertainty will disappear and we'll know if the Romney family will be moving into the White House or the Obamas will stay put," said Justin Harper, market strategist at IG Markets.

Meanwhile Greek woes have returned to haunt investors. The country's coalition government is trying to reach a consensus within the administration over a new set of austerity measures that could ensure the vital international bailout.

However, the government's decision to tighten its belt further has resulted in a nationwide outcry. Public and private sector workers are set to stage a 48-hour walkout in protest against the measures.
