Nikkei stock index logs record point gain after Aug. 5 sell-off

The Nikkei stock index surged over 10 percent Tuesday morning, marking a record intraday point gain as investors scooped up battered shares from a dramatic sell-off the previous day, Kyodo reports.

The benchmark had risen to an intraday high of 34,911.80 at 10:03 a.m., up 3,453.38 points from the previous day's close and exceeding the 2,677.54 point gain registered on Oct. 2, 1990.

The Nikkei ended Monday with a record 4,451.28 point decline.

At 11 a.m., the 225-issue Nikkei Stock Average had gained 2,871.82 points, or 9.13 percent, from Monday to 34,330.24. The broader Topix index was up 202.78 points, or 9.10 percent, at 2,429.93.

Sentiment improved as the yen weakened, with the U.S. dollar bought back after the release of stronger-than-expected U.S. economic data, helping to lift export-oriented issues.

Circuit breakers were briefly triggered for Nikkei and Topix futures in the morning to halt trading amid volatile movements.

At 11 a.m., the dollar fetched 144.81-84 yen compared with 144.14-24 yen in New York and 143.47-52 yen in Tokyo at 5 p.m. Monday.
