AI Frenzy vs Oil Shock: Tomorrow's Wall Street Winner

On the 22nd (local time), U.S. stocks in New York closed mixed amid a sharp rise in crude oil prices and cautious sentiment ahead of big-tech earnings. The S&P500 fell 0.1% to 7498.96, the Nasdaq slipped 0.6% to 25690.90, and the Dow closed virtually unchanged at 52218.58.

Brent crude rose 3.4% to $94.07 per barrel, briefly topping $95 intraday to test its highest level in six weeks. Fears of shipping disruptions through the Strait of Hormuz amid a potential war with Iran stoked concerns about re-accelerating inflation and prompted speculation of further Fed tightening, while the U.S. 10-year Treasury yield climbed to 4.65%, weighing on growth stocks.

During the session, defensive, high-dividend names such as Philip Morris and AT&T outperformed on better-than-expected results, and AI-server maker Super Micro Computer surged nearly 18% on improved margins. In contrast, many leading AI stocks pulled back as the burden of recent gains combined with rising rates.

After the close, Alphabet, Tesla, and IBM reported Q2 results, previewing tomorrow’s trading direction. Alphabet demonstrated the payoff from its AI investments with approximately $120 billion in revenue and cloud sales growing in the 80% range, but shares remained directionless in after-hours trading after raising its 2026 capex guidance to $180–190 billion. Tesla delivered $28 billion in revenue—strong on the top line—but missed profit consensus and slid about 3% in aftermarket trading.

With investors refraining from adding leverage ahead of the late-July FOMC meeting and subsequent big-tech earnings, oil prices, bond yields, and Middle East geopolitical risks are likely to dictate U.S. stock volatility in the near term.
