were near flat early Wednesday as investors watched to see if the benchmark index could return to its all-time high.

Futures tied to the broad index ticked up less than 0.1%, while Dow Jones Industrial Average futures inched higher 23 points. Nasdaq 100 futures were flat.

The S&P 500 jumped more than 1% in Tuesday's session as oil prices fell on bets that the ceasefire between Iran and Israel could last. With that gain, the index now sits less than 1% off its record high.

The Nasdaq Composite also popped more than 1%, while the Dow rallied more than 500 points. The Nasdaq 100 added 1.5% to end at a record closing level. Oil prices have cratered over the past two days, with West Texas Intermediate crude futures dropping 6% Tuesday. These declines have helped lift stocks.

The Israel-Iran conflict marks the latest obstacle the market has seemingly shaken off this year. Traders hoped that a delicate ceasefire between the two nations — announced by President Donald Trump — would hold. Even as investors worry about variables like a resurgence of inflation tied to tariffs and the strength of the consumer, U.S. stocks have continually rebounded from dips over recent months.

"The market continues to drive higher," said Joe Terranova, senior managing director for Virtus Investment Partners, on CNBC's "Halftime Report." "I use the world 'resiliency'; I will use that word over and over again because this is one of the most resilient markets that I have ever witnessed."

Investors will watch Wednesday for data on new home sales due in the morning. They'll also monitor Federal Reserve Chair Jerome Powell as he speaks before the Senate Banking Committee.

On the earnings front, traders will follow quarterly reports from General Mills, Paychex and Micron.
