TOKYO, Sept 12 (Reuters) - The Nikkei average rose 1.1 percent on Friday, buoyed by financial shares, with investors cheering news that U.S. investment bank Lehman Brothers <LEH.N> was in talks about a possible sale.
Improving investor confidence helped lift the overall market, including recently battered shares of trading houses and property firms such as Mitsui Fudosan Co <8801.T>.
Lehman and U.S. regulators were in intensive discussions about a number of options, including a complete sale, but the firm was resisting government intervention, a source with direct knowledge of the talks said. [
]"That is positive because that means the number of ailing entities will decrease through an industry realignment," said Masaru Hamasaki, senior strategist at Toyota Asset Management.
"But selling pressure awaits after short-covering because investors have become risk-averse on worries about the economy and corporate earnings."
The benchmark Nikkei average <
> added 128.49 points to finish the morning session at 12,230.99, after losing 2 percent the previous day.The broader Topix <

But even if problems at Lehman are worked out, worries about the U.S. financial sector will likely continue to haunt the market, market players said.
