Wall Street nosedives on trade-war worries

NEW YORK (Reuters) - Wall Street tumbled on Friday as investors, increasingly nervous about a potential U.S. trade war with China, shied away from risky bets going into the weekend as they looked for shelter from further declines.

The Dow Jones Industrial Average <.DJI> fell 424.55 points, or 1.77 percent, to 23,533.34, the S&P 500 <.SPX> lost 55.43 points, or 2.10 percent, to 2,588.26 and the Nasdaq Composite <.IXIC> dropped 174.01 points, or 2.43 percent, to 6,992.67.
