The S&P 500 and Nasdaq on Monday eked out record closing highs, although investors were cautious ahead of this week's consumer prices report, a Federal Reserve policy announcement and Apple's developer conference.

Providing some support to the Nasdaq and S&P 500, Nvidia shares ended up 0.7 percent, 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 on 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 US central bank may begin to cut interest rates.

The Dow Jones rose 0.18 percent to 38,868, the S&P 500 gained 0.26 percent to 5,360, and the Nasdaq added 0.35 percent to 17,192. (Reuters)
