The S&P 500 was marginally higher on Thursday, putting it just half a percent away from the all-time high it reached it January, testifying to the strength of the world's biggest economy and corporate sector.
If the index breaks above 2,872.87, it would notch its first record high since Jan. 26.
The Nasdaq was also less than 1% away from a record while the Dow remained 3.9% below its all-time high.
Against this backdrop, the CBOE Volatility Index (VIX), often viewed as a gauge of anxiety in financial markets, fell to a seven-month low of 10.17.
