The Nikkei stock average plunged to a fresh 17-year low Monday after Friday's tumble on Wall Street and a negative report on domestic machinery orders erased a rally sparked by a Finance Ministry comment out of Shanghai.
The 225-issue Nikkei plunged 321.10 points, or 3.05 percent, to close at an intraday low of 10,195.69, its lowest finish since Aug. 2, 1984, when it closed at 10,086.87.
The broader Tokyo Stock Price Index (Topix) of all first section issues plunged 24.85 points, or 2.30 percent, to 1,055.98, its lowest close since Jan. 12, 1999, when it finished at 1,055.93.
