U.S. stocks fell, with the S&P 500 posting the worst start to a year since 2016, amid concern the Federal Reserve will be forced to raise rates faster than some investors had anticipated.
After a record close for the S&P 500 on Monday, declines in megacaps such as Tesla Inc., Nvidia Corp. and Alphabet Inc. on Friday left the benchmark ending the start of the new year down 1.9% on the week. The tech-heavy Nasdaq 100 closed down more than 4% on the week.
