Providing some support to the Nasdaq and S&P 500, Nvidia shares ended up 0.7%, the session after a 10-for-one stock split. Some investors now believe the chip maker might be included in the blue-chip Dow.

The Consumer Price Index report for May is due Wednesday along with the conclusion of the Fed's two-day policy meeting.

The central bank, which will release updated economic and policy projections, is expected to hold interest rates steady. Investors will look for clues on when the U.S. central bank may begin to cut interest rates.
