Stocks hammered as sell-off moves from tech to other sectors

Investors pulled back on stocks Tuesday as a sell-off that began in tech companies broadened to other sectors, sending the major US indices down.

The Dow Jones Industrial Average tumbled about 450 points, or 1.3 percent, in mid-day trading. The S&P 500 was 0.8 percent lower and the tech-heavy Nasdaq Composite edged just 0.1 percent lower, but was down as much as 2.2 percent earlier in the day. Investor concerns over rising inflation costs have hit high-growth tech stocks in recent weeks. The Nasdaq is down nearly 5 percent since the start of the month. But the sell off spread Tuesday to other sectors, hitting everything from retailers to industrials and banks.
