TOKYO: Japan’s Nikkei share average fell on Friday, tracking Wall Street’s overnight weak finish, but the index gave up some of its losses as investors bought stocks on the dip.

The Nikkei index had fallen 0.52% to 31,266.84 by the midday break after opening at 0.85% lower. The index is set to lose 3.2% for the week.

The broader Topix was down 0.38% to 2,255.52 and on course to post a 2.2% weekly fall. “The market opened lower but the Nikkei narrowed its losses because investors bought back stocks at declines.

This has been a pattern in the recent market movements,“ said Jun Morita, general manager of the research department at Chibagin Asset Management.

US stocks ended lower overnight after US Federal Reserve Chairman Jerome Powell said that additional interest rate hikes could be warranted in view of economic resiliency and labor market tightness.

Investors were prompted to sell Japanese stocks after the yield on the benchmark 10-year US Treasury note hit the 5% mark for the first since July 20, 2007.

Japan’s 10-year government bond yield slipped slightly after the Bank of Japan announced measures to contain yields.

“For a while, the US Treasury yields will remain as a cue for Japanese equities,” said Masahiro Ichikawa, chief market strategist at Sumitomo Mitsui DS Asset Management.
