U.S. stocks are sinking on worries that Friday’s 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 was down 0.8% in early trading and on track for 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.
