Nikkei retreats from 30-year high as corporate earnings loom

Japanese shares retreated from a 30-year peak on Friday, as investors refrained from placing big bets ahead of the corporate earnings season while some locked in profit after the recent rally in global equities.

Nikkei share average edged down 0.33% to 28,663.27 as of 0140GMT, while the broader Topix eased 0.23% to 1,856.35. The index closed at a 30-year high on Thursday on investor optimism that new US administration's massive stimulus package will bolster growth.

"Today's decline is mainly due to profit-taking after US stocks touched new highs," said Hideyuki Ishiguro, senior strategist, Daiwa Securities.

"Investors are also holding off from buying ahead of earnings reports next week."

Wall Street peaked overnight, with both the S&P 500 and Nasdaq Composite closing at record highs, pushed upward by continued optimism about economic stimulus to counteract the Covid-19 pandemic promised by newly inaugurated US President Joe Biden.
