The S&P 500 fell 0.1% in afternoon trading, marking a reversal from earlier gains of up to 0.8%.

U.S. stocks also got some help Friday from a relatively calm bond market, where rising Treasury yields had been cranking up the pressure in recent months.
Treasury yields held relatively steady after an update on the measure of inflation that the Federal Reserve prefers to use came in almost exactly as economists expected. The yield on the 10-year Treasury rose to 4.54% from 4.52% late Thursday.
Yields have been generally climbing since September as the U.S. economy has remained much more solid than economists expected. More recently, worries about tariffs and other possible policies coming from President Donald Trump that could add upward pressure on inflation and the U.S. government’s debt have also sent yields higher.
The Fed left its benchmark interest rate unchanged as it closed out its most recent meeting Wednesday. The central bank is signaling a more cautious approach as it waits to see how policies under Trump will impact inflation and the broader economy.

“Markets are on edge watching President Trump’s plans to raise tariffs and tighten immigration policies, since both are pressuring the Fed to keep interest rates elevated," said Bill Adams, chief economist for Comerica Bank.
