The three major indexes had snapped a three-session losing streak on Wednesday. That came after President Trump said the US was in the final stages of negotiations with Iran.

Trump added on Wednesday that he was willing to wait “a couple of days” while Iran reviewed the latest US peace proposal. The supreme leader’s uranium directive quickly reversed that optimism.

Nvidia Earnings Draw a Mixed Response

Nvidia reported first-quarter results after the bell on Wednesday, beating analysts’ targets on both profit and revenue. The AI chipmaker also issued an upbeat forecast for chip sales.

However, investors had expected a stronger signal. The sales guidance beat was smaller than Wall Street had grown used to, and shares were flat in early premarket trading.

Deutsche Bank analyst Jim Reid noted that despite impressive growth and a 75% gross margin, the moderate guidance beat drew a lukewarm response from the market.

Oil Rises as Iran Talks Stall

Oil prices rose sharply on Thursday morning as the US-Iran deadlock continued. Brent crude climbed back above $106 a barrel, while West Texas Intermediate rose 2.5% to around $100.67.

Higher oil prices have weighed on bonds throughout the conflict. Markets are concerned that rising energy costs could push inflation higher, giving the Federal Reserve more reason to hike interest rates.

The yield on the 10-year Treasury note rose 3 basis points in early trading to 4.62%.

Shortly after Nvidia’s results dropped, SpaceX filed its S-1 registration statement with the Securities and Exchange Commission. The filing gave the public a rare look at the company’s finances ahead of a planned investor road show in June.

Earnings season continues to wind down this week. Walmart, Ross Stores, Workday, and Zoom Communications are all set to report results on Thursday.

Investors will be watching closely for any update on the Iran negotiations, which remain the biggest driver of market sentiment heading into the session.
