Tokyo - Tokyo stocks extended a losing streak in opening trade on Tuesday as investors searched for fresh trading pegs after the corporate earnings season.
The benchmark Nikkei 225 index, which fell for a fourth straight day on Monday, lost another 45.72 points, to 22 335.27 in the first few minutes while the broader Topix index slipped 3.11 points, to 1 780.38.
The two indices later regained some ground in see-saw exchanges and were flat more than an hour into trade.
"The Nikkei average will possibly correct its (rising) pace in the immediate future. Given that corporate earnings have been strong, however, the drops will not be deep," Masayuki Kubota, chief strategist at Rakuten Securities, said in a commentary.
The key index hit a quarter-century high last week amid easing concerns over geopolitical risks and expectations for sound corporate earnings.
Makoto Sengoku, market analyst at Tokai Tokyo Research Centre, said Tokyo stocks were now prone to speculative trade, which have resulted in sharp swings in prices.
"Company earnings were largely robust and Tokyo shares rose fast... This has become an incentive for speculation" to reap quick profits, he told AFP.
Going forward, investors are waiting for an expected US interest rate hike in December, which would push the yen lower to benefit Japanese exporters, as well as progress in US tax reform, he said.
