The Nasdaq and the S&P 500 on Monday closed at records as Wall Street prepared for a key meeting of the Federal Reserve later this week.
The S&P 500 closed up 0.18% to 4,255 to mark its third consecutive record closing high, while the Nasdaq climbed 0.74%.
The Dow Jones Industrial Average fell 85 points, or 0.25%, to 34,393. The blue chips on Monday traded off as much as 0.8%.
The S&P 500 on Friday posted its second consecutive record close, with investors assessing the Federal Reserve's stance that inflation spikes will prove to be transitory. The S&P 500 rose 0.4% last week.
The big event this week will be an announcement on interest rates from the Federal Reserve's policy-setting body, the Federal Open Market Committee, on Wednesday, followed by a news conference from Fed Chairman Jerome Powell.
The U.S. central bank isn't expected to take any action with respect to rates or a tapering of monthly asset purchases. Wall Street will be monitoring the meeting closely, however, for the Fed's forecasts on inflation and the strength of the economic recovery.
The Fed meets Tuesday and Wednesday amid a backdrop of the fastest rise in consumer prices in more than a decade and persistent questions about the nature - and staying power - of inflation as the economy nears its full exit from the coronavirus pandemic.
Any hint from Powell that inflation pressures may spark discussions about slowing the pace of the Fed's $120 billion in monthly bond purchases could rattle markets. A reiteration of the central bank's view that inflation pressures are "transitory" likely will add to market bullishness.
