Wall Street looked shaky during its opening on Wednesday, with U.S. stocks fluctuating as investors navigate a surge in oil prices amid ongoing tensions in the Middle East.

The S&P 500 slipped 0.3 percent, while the Dow Jones Industrial Average dipped by 14 points or less than 0.1 percent and the tech-heavy Nasdaq composite dropped 0.4 percent.

Crude oil prices surged nearly 3 percent, pushing Brent crude above the $75 mark, as markets reacted to growing concerns about potential disruptions in oil supply chains due to escalating conflicts in the Middle East.

Although Israel isn't a major player in the oil market, neighboring Iran's significant role as an oil producer has heightened fears that a broader conflict could impact global oil flow.

This rise in oil prices, while troubling for consumers, benefited U.S. oil giants like Exxon Mobil, which saw its shares climb 2 percent, continuing a strong week of gains.

On the corporate front, health insurer Humana took a dramatic hit, plummeting 20.5 percent after warning that a drop in its ratings for Medicare Advantage could affect revenues by 2026. The company cited potential errors in the Centers for Medicare and Medicaid Services' calculations and is actively seeking to challenge the ratings.

Nike also faced investor disappointment, dropping 7.8 percent despite posting stronger-than-expected quarterly profits. The sportswear titan fell short on revenue projections and faces challenges under incoming CEO Elliott Hill as it aims to revitalize its brand appeal.

Conagra Brands, the parent company behind popular products like Duncan Hines, saw an 8.7 percent drop after weaker-than-expected profits, attributed to supply chain disruptions during the critical summer grilling season.

Meanwhile, Tesla's stock slumped 5.8 percent, despite reporting increased vehicle deliveries for the quarter. While the company exceeded analyst expectations, investors appeared to have hoped for more significant growth.

In the bond market, U.S. Treasury yields edged higher after a report showed stronger-than-expected private-sector hiring in September. The ADP Research report highlighted that employers accelerated their hiring to a pace of 143,000, fueling anticipation ahead of Friday's broader jobs report from the government.

However, the overarching question for Wall Street remains whether the U.S. job market can sustain its strength amid the Federal Reserve's high interest rates, a measure aimed at curbing inflation without stifling economic growth.

As markets digest these shifts, all eyes remain on the geopolitical landscape and the upcoming U.S. jobs report, which could dictate the Federal Reserve's next move on interest rates.
