TOKYO, Oct 30 (Reuters) - Japanese shares jumped to aone-week high on Wednesday morning, led by SoftBank Corp surging on hopes of solid earnings, and on expectationsthe Federal Reserve will maintain its ultra-easy money policyfor at least the next few months.
Analysts widely expect the Fed's policy statement due at1800 GMT will not challenge the growing consensus that anytapering of its $85 billion of monthly asset purchases will bedelayed to March at the earliest.
The benchmark Nikkei rose 1.2 percent to 14,502.86in mid-morning trade, the highest since the middle of last week,after shedding 0.5 percent on Tuesday.
The broader Topix advanced 1 percent to 1,205.58 inrelatively active trade, with volume at 45.4 percent of its fulldaily average for the past 90 trading days.
Benchmark heavyweight SoftBank Corp climbed as much as 3.3percent after the Nikkei newspaper said the company's groupoperating profit could shoot up more than 70 percent for the sixmonths ended Sept. 30, driven by sales of iPhones and othersmartphones. It was the most-traded stock byturnover on the main board.
Mitsubishi Motors was also among top gainers,rising 4.1 percent, after the automaker on Tuesday reported arecord operating, recurring and net half-year profits inApril-September.
Taking the shine off the earnings glow on the day,heavyweight Fanuc Corp lost 3.3 percent.
The fall came after the industrial robots maker posted abetter-than-expected operating profit for the six months endedon September 30 but forecast a drop in its full-year profit. It was the sixth-most traded stock by turnoveron Topix.
The earnings season in Japan has failed to impress so far,but investors will have further trading opportunities fromanother batch of earnings later in the day from the likes ofHonda Motor Co Ltd and Nintendo Co Ltd.
The yen's retreat also helped to boost exporters' shares,which tend to underperform on any strength in the Japanesecurrency as it hurts their competitiveness overseas.
"There's been to date a sense that U.S. markets are offeringbetter returns than Japan and there may have been assetreallocation to U.S. from Japan," said Stefan Worrall, directorof equity cash sales at Credit Suisse in Tokyo.
"Ultimately if U.S. continues to show risk-on, Japan canonly follow, once the noise of earnings is over," he added.
The yen stepped back to around 98.25 per dollar,reversing its recent gains stemming from expectations that theFed will delay scaling back its stimulus. The dollar has startedto pull up given the Fed view is fully priced in by markets.
Toyota Motor Corp and Mazda Motor Corp added 1.6 percent and 1.8 percent, respectively.
The U.S. S&P 500 index ended at an record high on Tuesday,having gained 5.4 percent this month. In contrast, the Nikkeiwas almost flat in the same period.
But analysts at Nomura said the Nikkei could eventuallycatch up as Japanese shares look undervalued.
"The trend for P/E levels in the U.S. and Japan is towardconvergence," said Hiromichi Tamura, chief strategist at Nomura,noting that the P/E ratio for the TOPIX is approximately 14,compared to around 15 for the S&P 500.
