U.S. stocks were mixed on Tuesday as investors weighed softer energy prices against the risk of another Federal Reserve rate hike this year. The S&P 500, Dow and Nasdaq 100 were slightly higher, with the S&P 500 testing a record high. Optimism from Pakistani and Qatari authorities over a possible U.S.-Iran deal that could restore oil trade through the Persian Gulf helped trim a rebound in wholesale fuel prices that had followed President Trump sharpening his rhetoric on Tehran. Treasury yields eased, offering some relief to banks, and JPMorgan and Goldman Sachs edged higher. Nvidia gained 1.5% after raising $500 billion privately with banks to fund more AI infrastructure, a move that increases leverage in the sector. Intel, by contrast, extended the previous session's 4% decline with another 1.5% drop after increasing its expected stock sale by $5 billion to $20 billion. Markets are now awaiting Wednesday's CPI (Consumer Price Index, a key inflation gauge) release after multiple FOMC (Federal Open Market Committee, the Fed's rate-setting panel) members signaled a possible hike next month. SCMI and CoreWeave are due to report results after the bell.
