Stocks dropped Monday as technology companies came under fire and fears grew about a trade war with China.

It was a broad sell-off: The Dow Jones industrial average plunged more than 700 points, or 3 percent, in afternoon trading. The Standard & Poor’s 500-stock index was down 3.2percent and the tech-heavy Nasdaq Composite was down 3.5 percent as volatility continues to rock markets.

All three indexes are negative for the year and are in correction territory. A correction is generally considered a 10 percent drop from its peak.
