TOKYO, Jan 28 (Reuters) - The Nikkei average fell 0.4 percent on Wednesday as investors dumped shares in companies reporting grim earnings such as Nomura Holdings <8604.T>, while recent gainers lost ground after sharp gains the previous day.
Nomura, Japan's largest brokerage, slid nearly 4 percent, after posting a record $3.8 billion yen quarterly loss, hit by the cost of integrating Lehman Brothers' operations, soured trades and its exposure to Iceland and Bernard Madoff. [
]But major banking shares such as Mitsubishi UFJ Financial Group <8306.T> gained after the Japanese government said it would use public funds to help non-financial companies, easing worries about the risk of bad loans.
"Profit-taking is dominating the market after yesterday's huge gains, but I don't expect it to fall too much as external factors -- gains in U.S. stocks and a softer yen -- are not bad," said Soichiro Monji, chief strategist at Daiwa SB Investments.
"But investors have strong concerns about manufacturers' earnings because of their exposure to the deteriorating global economy and the risk that the yen could appreciate going forward."
The benchmark Nikkei <
> shed 29.61 points to 8,031.46. It jumped 4.9 percent on Tuesday to book its biggest one-day gain since Dec 15. The broader Topix < > slipped 0.6 percent to 800.85.The Dow Jones <
> rose 0.7 percent on Tuesday amid a rare bit of encouraging news on the earnings front from companies, including American Express <AXP.N>.Some market analysts said technical indicators show the Nikkei average may be heading for further gains.
"Charts tell us the Nikkei will likely move to near 8,400, the level of its 25-day moving average," said Fumiyuki Nakanishi, manager at SMBC Friend Securities.
NOMURA DOWN
Nomura shares lost 3.6 percent to 616 yen, although market players said the market had largely factored in the brokerage's poor results.
Recent gainers fell, with Toyota Motor Corp <7203.T> down 0.8 percent at 2,955 yen and Fast Retailing Co <9983.T> shedding 2.5 percent to 11,110 yen.
Canon Inc <7751.T> dipped 0.2 percent to 2,575 yen after a newspaper reported the camera and office equipment maker's operating profit will likely drop about 60 percent this year primarily due to the strong yen. [
]Canon is set to announce its 2008 results and outlook for 2009 at 3 p.m. (0600 GMT) on Wednesday.
Shares of Toshiba Corp <6502.T> slipped 1.1 percent to 371 yen on a report that the firm plans to shutter some assembly plants for system and discrete chips in Japan and instead expand output in Thailand and Malaysia and from outside suppliers. [
]Mitsubishi UFJ, Japan's largest bank, gained 2 percent to 507 yen, while Sumitomo Mitsui Financial Group <8316.T>, which is set to report earnings after the close, jumped 3 percent to 3,420 yen.
"Mega banks should be a buy on the news, as the government will protect banks in case they lent to companies that may end up not being able to pay back the money they borrowed," said Nakanishi at SMBC Friend Securities.
Trade was moderate on the Tokyo exchange's first section, with 887 million shares changing hands, compared with last week's morning average of 824 million.
