Japan's Nikkei index nose-dives in morning trade

Japanese shares plunged in morning trade Friday as jittery investors dumped shares following massive overnight losses on Wall Street. The benchmark Nikkei 225 index fell 736.40 points, or 8 percent, to 8,421.09 as of 10:20 a.m. At one point Japan's key index plummeted 1,042.08 points, or 11.4 percent, before rebounding. The massive sell-off in Tokyo came after the Dow Jones industrial average Thursday dropped 679 points, or 7.3 percent, to close below the 9,000-line for the first time in five years. "Selling is unstoppable in New York and Tokyo. Investors were gripped by fear," said Yutaka Miura, senior strategist at Shinko Securities Co. Ltd. "They were worried about a severe slump in the global economy."
