TOKYO, Jan 21 (Reuters) - Japan's Nikkei average slipped 1.9 percent on Wednesday after earlier hitting a two-month low on rekindled fear about the global financial sector that sent banks such as Sumitomo Mitsui Financial Group <8316.T> sliding.
Tech shares extended losses and exporters slipped as the dollar remained below 90 yen, while Sony Corp <6758.T> fell 2.7 percent after a newspaper said it is preparing to announce on Wednesday or Thursday details of its December restructuring plan, including where job cuts will fall. [
]But shares of Elpida Memory <6665.T> jumped over 5 percent after the company said it was in talks with Taiwanese DRAM makers including Powerchip <5346.TWO>, ProMOS Technologies <5387.TWO> and Rexchip, on a possible merger as well as other options. [
]"There's no question that worry about the financial system has revived, but it's different from last year -- there's no panic," said Takashi Ushio, head of the investment strategy division at Marusan Securities.
"There's now a safety net in place and people are much more determined to keep things from falling apart."
Disappointment with U.S. President Barack Obama's inauguration speech, which laid out few new details on how his administration will tackle the banking crisis and flagging economy, helped push stocks lower.
"People still have expectations for his economic policies, but we know nothing concrete about them, so the market has no choice but to focus on the real economy and earnings," said Yutaka Miura, chief technical analyst at Shinko Securities.
But other market players said hopes that helped power a global stock rally around the New Year had been unrealistic.
"As for Obama, perhaps you can say his impact has worn off, but soon he'll actually start carrying out his policies and we'll start seeing a reaction to what he really does," said Nagayuki Yamagishi, a strategist at Mitsubishi UFJ Securities.
