TOKYO, Oct 6 (Reuters) - The Nikkei share average was flat on Tuesday, with banking shares such as Mitsubishi UFJ Financial Group <8306.T> gaining after their U.S. peers rallied following a Goldman Sachs upgrade on the bank sector.
But Fast Retailing <9983.T> slid 3.1 percent, weighing on the market a day after leaping 15 percent on news that same-store sales at its Uniqlo casual-clothing chain in Japan jumped 32 percent in September.
Market players said they were worried about the impact of the recent strength of the yen <JPY=> on exporters' earnings, dampening investor confidence and capping gains in the overall market.
"Although gains are still due to short-covering, Goldman's upward revisions for bank earnings forecasts in the United States are helping bank shares here higher," said Takahiko Murai, general manager of equities at Nozomi Securities.
"But recent strength in the yen is keeping investors from actively buying on dips as the strong yen could force exporters to lower their earnings forecasts for the second half of the business year."
The benchmark Nikkei <
> added half a point to 9,675.00. It fell 0.6 percent the previous day to book its lowest finish since July 21 at well below its 25-day moving average. Last week, the index shed 5.2 percent, its worst weekly loss in about three months.The broader Topix <
> inched up 0.1 percent to 868.01."If the Nikkei breaks below 9,500, the next target will likely be around 9,000, provided the market sees further strength in the yen and another round of a fall in U.S. stocks," said Yutaka Miura, a senior technical analyst at Mizuho Securities.
Mazda Motor <7261.T> jumped 4.3 percent to 193 yen after it said it would raise up to $1.1 billion in a share sale to invest in hybrid and other technologies in what analysts said was a long-overdue bid to close the gap with rivals. It also halved its net loss forecast for the year to March. [
]BANKS GAIN, FAST RETAILING DOWN
U.S. financial stocks rallied on Monday, and were the top positive on the S&P 500 index <.SPX> after Goldman Sachs upgraded the large-cap bank sector, saying share prices for companies in the industry didn't reflect their earnings power. [
]Japan's top bank Mitsubishi UFJ climbed 2 percent to 464 yen and Mizuho Financial Group <8411.T> added 1.7 percent to 182 yen.
High-tech exporters also gained after optimism about upcoming U.S. earnings and strong services sector data boosted Wall Street, though investors remained cautious about moves in the currency market. [
]The yen stood around 89.10 yen to the dollar <JPY=> in early Asia trade. It hit an eight-month high of 88.23 yen to the greenback last week.
Many Japanese exporters have set their exchange rate assumptions for the dollar around 90-95 yen for the current fiscal year to March. A stronger Japanese currency eats into exporters' profits when they are repatriated.
Tokyo Electron <8035.T> gained 1.7 percent to 5,300 yen and Kyocera Corp <6971.T> advanced 1.3 percent to 7,840 yen. Honda Motor Co <7267.T> added 1.4 percent to 2,630 yen.
Fuji Heavy Industries <7270.T> advanced 3.8 percent to 329 yen after the Mainichi newspaper reported Toyota Motor Corp <7203.T> is considering developing electric vehicles (EVs) with the Subaru brand maker and hopes to start selling them in the early 2010s. [
]Shares of Toyota rose 0.9 percent to 3,380 yen.
But Fast Retailing slid to 13,110 yen to become the top drag on the Nikkei 225.
Defensive sectors also fell after gaining the previous day in the face of a decline in shares of exporter companies.
KDDI Corp <9433.T>, Japan's No.2 phone operator, shed 2 percent to 501,000 yen and NTT DoCoMo <9437.T> slipped 1.5 percent to 140,200 yen.
Kao Corp <4452.T>, Japan's largest maker of toiletries, fell 1.1 percent to 2,215 yen.
Some 925 million shares changed hands on the Tokyo exchange's first section, roughly in line with last week's morning average.
