U.S. stocks fell Friday on worries that good news on the job market may be too good and prove to be bad for Wall Street by keeping inflation and interest rates high. The S&P 500 tumbled 1.5% to close its fourth losing week in the last five.

U.S. stock futures quickly tumbled after the government said U.S. employers added a stronger-than-expected 256,000 jobs in December. Economists were expecting hiring to increase by 153,000.
