(Reuters) - U.S. stocks declined broadly on Tuesday as China's devaluation of its yuan currency hit companies with a big exposure to the world's No. 2 economy and added to worries about the global economic outlook.
Apple Inc (AAPL.O) shed 5.2 percent to end at $113.54 in its biggest daily percentage decline since January 2014, making the stock the biggest drag on all three major U.S. indexes. Jefferies also raised concerns about the demand for the iPhone, primarily in China.
Among other companies with big exposure to China, Caterpillar (CAT.N) was down 2.6 percent at $78.04 and Yum Brands (YUM.N) dropped 4.9 percent to $83.54. General Motors (GM.N) shares lost 3.5 percent to $30.83, though it said the devaluation of the yuan would have a "limited and manageable" impact on its business.
The Dow Jones industrial average .DJI fell 212.33 points, or 1.21 percent, to 17,402.84; the S&P 500 .SPX index lost 20.11 points, or 0.96 percent, to 2,084.07 and the Nasdaq Composite .IXIC dropped 65.01 points, or 1.27 percent, to 5,036.79.
"Obviously, this devaluation seems to suggest there's a lot of weakness, and we're in thinly-traded markets right now," said Eric Kuby, chief investment officer at North Star Investment Management Corp in Chicago.
"To a certain extent, the stocks that have propped up the market this year have slowly fallen out of favour, so I think that you're seeing a little bit of a flight to safety."
The sudden currency adjustment by the world's top metals consumer pushed copper and aluminium to six-year lows, and the S&P materials index .SPLRCM dropped 1.9 percent, leading S&P 500 sector declines. Freeport-McMoRan (FCX.N) slid 12.3 percent to $10.22.

The day's stock market declines followed a rally on Monday that gave the S&P 500 its biggest increase since May.
Among the day's gainers, Google (GOOGL.O) rose 4.1 percent to $690.30 after it said it would overhaul its operating structure.
After the bell, shares of General Electric (GE.N) edged up 0.4 percent after it said it would sell its U.S. healthcare finance unit and $8.5 billion of healthcare-related loans to Capital One Financial Corp (COF.N). GE shares ended the regular session down 2 percent at $25.71.
