TOKYO (Kyodo) -- Tokyo stocks rebounded Thursday, with the Nikkei index briefly gaining over 2 percent, driven by dip-buying after recent sharp losses.

The 225-issue Nikkei Stock Average ended up 671.41 points, or 1.34 percent, from Wednesday at 50,883.68. The broader Topix index finished 45.16 points, or 1.38 percent, higher at 3,313.45.

On the top-tier Prime Market, the main gainers were nonferrous metal, machinery and securities house issues.

The U.S. dollar was directionless mostly in the upper 153 yen range in Tokyo, amid a lack of fresh trading incentives, dealers said.

At 5 p.m., the dollar fetched 153.86-88 yen compared with 154.05-15 yen in New York and 153.54-56 yen in Tokyo at 5 p.m. Wednesday.

The euro was quoted at $1.1508-1509 and 177.07-11 yen against $1.1487-1497 and 177.04-14 yen in New York and $1.1487-1489 and 176.38-42 yen in Tokyo late Wednesday afternoon.

The yield on the benchmark 10-year Japanese government bond ended at 1.680 percent, up 0.020 percentage point from Wednesday's close, as the debt was sold amid increased investor risk appetite following the Nikkei's rise.

Stocks climbed as a wide range of shares were bought after the benchmark Nikkei lost more than 2,000 points over the two previous days, and key U.S. stock indexes rose as solid economic data helped ease concern about a slowing labor market, brokers said.

However, buying later slowed as investors became cautious about further possible pullbacks after recent strong gains that saw the Nikkei surge more than 7,400 points in October, its largest-ever monthly point rise.

"The rises driven by artificial intelligence-related stocks seem to have run their course and further gains with such buying are likely to be limited" until AI chip giant Nvidia Corp. releases earnings results later this month, said Masahiro Yamaguchi, head of investment research at SMBC Trust Bank.

"In the meantime, Tokyo stocks could come under pressure if there is news suggesting the U.S. economy is not doing well," he added.
