Apple's shares tumbled 6.8 percent, taking its market value below $1 trillion, after the iPhone maker warned sales for the crucial holiday quarter would likely miss expectations.
U.S. job growth rebounded sharply in October and wages recorded their largest annual gain in 9-1/2 years, pointing to further labor market tightening that could encourage the Federal Reserve to raise interest rates again in December.
