S&P, Nasdaq notch biggest weekly losses since March

STORY: Wall Street see-sawed on Friday then closed slightly lower after a tumultuous week as investors digested the Federal Reserve's hawkish outlook.

The Dow shed three-tenths of a percent, the S&P 500 lost two-tenths and the Nasdaq dipped marginally.

The Fed this week let its key interest rate stand, but it updated its projections to suggest that restrictive monetary policy will remain in place longer than previously anticipated.

On Friday, Fed Governor Michelle Bowman supported the hawkish sentiment by saying the central bank should “raise rates further and hold them at a restrictive level for some time” to bring inflation down to the Fed’s 2% target.

“That has ramifications, particularly for growth equities, but really for the entire global economy….”

“And I think the realization that's hit this week is really what started to weigh on investors, and why we're seeing the weakness... certainly weak today."
