TOKYO, Dec 11 (Reuters) - Japan's Nikkei average slipped 0.8 percent on Thursday, losing some gains made this week as the yen rose against other currencies and doubts emerged over whether a bailout plan for U.S. automakers will be quickly approved.
But some big stocks bucked the trend, with Sumitomo Mitsui Financial Group <8316.T> climbing after a report that it would raise $7.6 billion in capital, much more than earlier plans, while Japan Tobacco Inc <2914.T> jumped on a report that the tobacco tax would not be hiked.
Market analysts said investors locked in profits after the the benchmark Nikkei <
> climbed 9.4 percent over the past three days, and sentiment was weak as traders kept a close eye on currency moves and the fate of U.S. automakers."The prospects for corporate earnings are dismal, and investors are in no position to keep buying stocks," said Kenichi Hirano, operating officer at Tachibana Securities.
"Charts seem to indicate the market might have hit a bottom, but I think it's still too premature to say it's completely bottomed out."
The benchmark Nikkei <
> fell 68.97 points to 8,591.27, although it was still above its 25-day moving average. It gained more than 3 percent on Wednesday to book its highest close since Nov. 12.The broader Topix <
> inched up 0.2 percent to 836.53."Investors also want see how the U.S. auto industry bailout pans out, with approval by the Senate looking a bit uncertain," said Yutaka Miura, a senior technical analyst at Shinko Securities.
U.S. stocks rose in choppy trade on Wednesday, with the Dow Jones industrial average <
> ending up 0.8 percent.The dollar fell 0.2 percent to 92.60 yen <JPY=> from late U.S. trading. Investors fret over a stronger yen as it curbs Japanese exporters' overseas profits when they are repatriated.
U.S. lawmakers opened debate on Wednesday on legislation to bail out U.S. auto companies. Following debate, a vote on passage in the House of Representatives was expected later in the evening.
But hopes evaporated for quick action by the Senate where Republicans, some of whose votes would be necessary to ensure passage, threatened procedural moves to slow or even block the effort to authorise up to $14 billion in bridge loans. [
