TOKYO, Dec 30 (Reuters) - Japan's Nikkei average is poised to book gains for 2009, with shares of high-tech exporters having led a rebound rally on a weaker yen and as economic stimulus measures helped turn around the world economy.
On the Tokyo stock market's final trading day of the year the Nikkei was showing a rise of about 20 percent for 2009, following a 42 percent plunge -- the biggest loss in its 58-year history -- last year when investors saw the global financial crisis take a heavy toll on risky assets including stocks.
The benchmark was flat by mid-afternoon on Wednesday after rising to a four-month high as high-tech exporters such as Canon Inc <7751.T> received a boost from a weaker yen.
But gains were limited as Japan Airlines (JAL) <9205.T> at one point tumbled 32 percent to a record low of 60 yen on growing investor worries the struggling carrier will be restructured in bankruptcy court as part of a state bailout. [
]Transport Minister Seiji Maehara said cabinet ministers would meet at 6 p.m. (0900 GMT) on Wednesday to discuss JAL. [
]"Weakening in the yen and a gradual recovery in the economy and growing demand for companies helped buoy the market in time for the year-end," said Naoki Koga, a senior fund manager at Toyota Asset Management.
"But domestic-demand sectors, on the other hand, fell out of favour this year due to uncertainty about the government's policy. Financial stocks, in particular, were hurt by worries about capital raisings."
The benchmark Nikkei <
> was flat at 10,634.27 after earlier rising to 10,707.51, its highest since Aug. 31. It has clawed back about 50 percent since hitting a 26-year closing low in March.The broader Topix <
> dipped 0.2 percent to 914.03.In one encouraging technical sign for the Nikkei, its 25-day moving average edged above its 75-day moving average, a phenomenon known as the "Golden Cross" that can often indicate further rises and is regarded as a buying signal.
"We're likely to see the market off to a strong start in the new year. But the focus in the first half will be on corporate earnings for the next business year, with government policies holding a key for their direction," Koga said.
Japanese financial markets will be closed on Thursday and Friday for the New Year's holiday.
TECH STOCKS GAIN, JAL DRAG
The dollar's surge against the yen to a two-month high helped shares of exporters on Wednesday. Investors welcome a weaker yen because it boosts exporters' profits when repatriated.
The greenback rose 0.2 percent to 92.14 yen <JPY=>, led by buying on last-minute commercial needs before the end of the year. [
]Chip-tester maker Advantest Corp <6857.T> rose 0.6 percent to 2,450 yen, Canon Inc <7751.T> gained 1 percent to 3,950 yen and Hitachi Ltd <6501.T> added 4.4 percent to 286 yen. Honda Motor Co <7267.T> edged up 0.3 percent to 3,150 yen.
But JAL lost 25 percent to 66 yen.
Sources have told Reuters that a state-backed turnaround fund now weighing whether to bail out JAL is considering using a bankruptcy procedure similar to Chapter 11 in the United States as part of its revival plan.
The Nikkei business daily reported that the fund plans to guarantee the struggling carrier's fuel payments and other commercial transactions if it is restructured in bankruptcy court. [
]"There's still a lot of uncertainty about what's going to happen to JAL, and this is inviting selling," said Tomomi Yamashita, a fund manager at Shinkin Asset Management.
Japan's top banks, JAL's main creditors, fell amid growing investor worries about the struggling carrier's possible bankruptcy.
Mitsubishi UFJ Financial Group <8306.T> fell 0.2 percent to 453 yen and Mizuho Financial Group <8411.T> slipped 1.2 percent to 165 yen.
Bankruptcy proceedings usually lead to a sharp cut in the payment of sales receivable and other creditor claims.
HIGH-TECHS SHINE IN 2009, BANKS LAG BEHIND
High-tech exporters led gains in the Japanese market in 2009, while banking shares lagged behind, hurt by worries about equity financing as well as growing fear that JAL might go bankrupt.
The Tokyo stock market's electrical machinery index <.IELEC.T> has gained about 40 percent this year, outperforming a gain of around 6 percent in the Topix index and a more than 20 percent slide in the banking index <.IBNKS.T>.
Market analysts say the big banks have been hit by a combination of concern about JAL and worry that Mizuho and Sumitomo Mitsui Financial Group might be forced into equity fundraising early next year.
Japan's top bank Mitsubishi UFJ has already raised about 1 trillion yen through a new share issue. [
]Investors will keep a close eye on currency moves in the new year as that will impact earnings prospects for exporters, analysts said. (Additional reporting by Elaine Lies; Editing by Michael Watson)
