TOKYO (Kyodo) -- Tokyo stocks were mixed Monday morning as investors bought bank issues on prospects for higher long-term interest rates, but technology shares fell after sharp gains last week.

The 225-issue Nikkei Stock Average fell 232.22 points, or 0.58 percent, from Friday to 39,699.76. The broader Topix index was up 13.62 points, or 0.50 percent, at 2,764.66.

The U.S. dollar was directionless, trading mostly in the mid-155 yen range in Tokyo, with the Bank of Japan's decision Friday to raise its policy interest rate and its governor's press conference having a limited impact on the market, dealers said.

At noon, the dollar fetched 155.63-65 yen compared with 155.97-156.07 yen in New York and 155.37-39 yen in Tokyo at 5 p.m. Friday.

The euro was quoted at $1.0466-1.0467 and 162.88-92 yen against $1.0483-0493 and 163.64-74 yen in New York and $1.0460-0462 and 162.52-56 yen in Tokyo late Friday afternoon.

Stocks opened higher as bank shares were lifted by expectations of improved profits as long-term interest rates climbed Friday after the BOJ tightened monetary policy.

But the benchmark Nikkei later slipped into negative territory, as investors unloaded heavyweight technology shares after surges last week triggered by the announcement of a $500 billion U.S. artificial intelligence investment project.
