TOKYO, Aug. 27 (Xinhua) -- Tokyo stocks ended mixed Wednesday amid a wait-and-see mood before U.S. chip giant Nvidia Corp. releases its earnings report.

Japan's benchmark Nikkei stock index, the 225-issue Nikkei Stock Average, ended up 125.87 points, or 0.30 percent, from Tuesday at 42,520.27.

The broader Topix index, meanwhile, finished 2.25 points, or 0.07 percent, lower at 3,069.74.

On the stock market, many investors sat on the sidelines before the release of Nvidia's earnings report, looking for whether the results would lead to volatility on U.S. markets. Meanwhile, a sharp rise in a major pharmaceutical on solid drug trial results improved mood, analysts said. ■
