Stock Market Today: Dow Rises as Big Tech Stocks Weigh on Nasdaq After Weekend of U.S.-Iran Peace Talks; SpaceX Continues To Fall

U.S. stocks were mixed, with the Dow up 0.4% while the S&P 500 fell 0.3% and the Nasdaq dropped 1.2% as geopolitics and megacap tech weakness weighed on sentiment. Oil eased after Treasury authorized Iranian oil sales for 60 days, while the 10-year Treasury yield rose to 4.51% ahead of Thursday's PCE inflation reading. Micron jumped 5% to a record high ahead of Wednesday earnings, Apogee surged 47% on AbbVie's $10.9B acquisition, and SpaceX fell nearly 9% to its lowest level since IPO day.

Analysis

The market is pricing a classic split-regime tape: lower geopolitical risk and softer energy prices support duration-sensitive assets, while higher real-rate expectations and a firmer dollar punish long-duration mega-cap tech. The important second-order effect is that easing oil removes an immediate inflation impulse, but it does not remove the Fed’s hawkish bias; that keeps the front end anchored higher and makes multiple compression in the most crowded AI winners more likely over the next 1-3 weeks.

The semiconductor leadership is becoming more selective. Memory and storage beneficiaries look like the cleaner expression of AI capex than platform mega-caps because the trade is increasingly tied to inventory tightness and pricing discipline, not just narrative velocity. That creates a subtle rotation: suppliers with near-term earnings leverage and visible shipment constraints should continue to outperform, while broad AI proxies that already discount flawless demand may underperform on any hint of margin normalization.

The SpaceX move is a warning signal for high-float-challenged momentum names: once marginal buyers step away, valuation becomes much more sensitive to new supply, debt events, and index inclusion mechanics. In contrast, the AbbVie/Apogee deal suggests M&A remains active where strategic scarcity is real; this keeps a bid under cash-flow-rich pharma and biotech names with differentiated assets, especially in areas where incumbents need pipeline replacement rather than platform optionality.

Key Decisions for Investors

• Short GOOG/AMZN vs long SNDK/INTC/AMD for 1-2 weeks: the pair favors direct AI supply-chain beneficiaries over mega-cap beta. Risk/reward improves if rates stay firm and PCE prints hot; cover if Nasdaq breadth improves materially.
• Buy MU upside into earnings via call spread or limited-risk long premium, sized for a 48-72 hour catalyst. The setup is asymmetric because the market is rewarding visible pricing power; stop if management signals any demand normalization or ASP pressure.
• Go long ABBV against a basket of large-cap pharma with weaker pipelines for 1-3 months. The acquisition premium de-risks the story and should support multiple expansion if M&A breadth remains active.
• Fade SPCX on rallies with put spreads or a small short against index-inclusion hype, targeting the next 2-8 weeks. The trade works if lock-up overhang and additional supply from financing events overwhelm passive demand.
• If PCE is above consensus, rotate temporarily from AAPL/TSLA into T-bills/short-duration defensives for 3-5 sessions; if PCE is soft, use that as the signal to re-add Nasdaq beta after the initial squeeze lower in yields.
