TOKYO, Nov. 25 (Xinhua) -- Tokyo stocks ended mixed Tuesday, as buying spurred by overnight gains on Wall Street was offset by selling of heavyweight SoftBank Group.

The benchmark Nikkei stock index, the 225-issue Nikkei Stock Average, ended up 33.64 points, or 0.07 percent, from Friday to 48,659.52.

The broader Topix index, meanwhile, finished 6.84 points, or 0.21 percent, lower at 3,290.89.

Japanese stock markets were closed on Monday for a national holiday.

Heavyweight chip shares were sought after U.S. stocks rallied on hopes the Federal Reserve will cut interest rates soon, briefly sending the benchmark Nikkei above the 49,000 line, analysts said.

Meanwhile, the market was later weighed down by a plunge in SoftBank Group amid concerns about intensifying competition in the artificial intelligence sector following the announcement last week of Google's new Gemini generative AI model. ■
