Nikkei ends five-day winning run as US-Japan trade talks weigh

TOKYO, July 1 (Reuters) - Japan's Nikkei share average snapped a five-day winning streak to fall more than 1% on Tuesday, as investors sold stocks amid uncertainty over U.S.-Japan trade talks.

The Nikkei .N225 fell 1.24% to 39,986.33, slipping from the highest level since mid-July, which it reached in the previous session.

The broader Topix .TOPX slipped 0.73% to 2,832.07.

"The market was overheated, but there were some factors that boosted demand last month," said Hiroyuki Ueno, chief strategist at Sumitomo Mitsui Trust Asset Management.

Japanese equities mirrored a rally in U.S. stocks in the past several sessions, but demand was also supported by dividend payouts investors received after corporate shareholders' meetings in June, as well as corporate share buybacks, said Ueno.

The Nikkei rose 6.6% in June, marking its biggest monthly gain since February 2024. In the last five sessions of June, the index gained 5.5%.

The Relative Strength Index (RSI), a technical measure for investment momentum, dropped to 66.6 on Tuesday from the "overbought" condition of 74.5.

Meanwhile, U.S. President Donald Trump expressed frustration with U.S.-Japan trade negotiations on Monday, casting clouds over ongoing trade talks between the two countries.

U.S. Treasury Secretary Scott Bessent also warned that countries could be notified of sharply higher tariffs as a July 9 deadline approaches despite good-faith negotiations.

"Investors weighed trade factors, but if the outlook of the talks becomes clear, then the market gauges stocks with fundamentals and the Nikkei has the potential to rise further," said Ueno.

Uniqlo-brand owner Fast Retailing 9983.T fell 4.16% to drag the Nikkei the most. Chip-equipment maker Tokyo Electron 8035.T slipped 2.2%.

Bucking the trend, utility Tokyo Electric Power Holdings 9501.T jumped 9.98% to become the biggest percentage gainer on the Nikkei.
