You're listening to 7 Horns AI — your AI-powered market update. Good evening, everyone, and welcome to your market wrap-up for Tuesday, May twenty-sixth, twenty twenty-six. Markets returned from the Memorial Day holiday in a predominantly upbeat mood today. The S&P five hundred notched its nineteenth record close of twenty twenty-six, gaining zero point six two percent to seven thousand five hundred nineteen point four seven. The tech-heavy Nasdaq Composite also reached a new high, marking its fifteenth record close, advancing one point one nine percent to twenty-six thousand six hundred fifty-six point one eight. In contrast, the Dow Jones Industrial Average slipped modestly, shedding zero point two three percent to close at fifty thousand four hundred sixty-one point six eight. The clear standout was the Philadelphia Semiconductor Index, which surged over five percent to a new record of twelve thousand nine hundred three point one nine. Intraday, markets opened higher, buoyed by US-Iran negotiation hopes and falling bond yields, with the ten-year Treasury yield dropping to four point four nine percent. The Nasdaq led throughout the session, driven by semiconductor gains. While some afternoon enthusiasm softened after reports of US defensive strikes in Iran, the S&P five hundred and Nasdaq held comfortably positive. It was a tech-driven, risk-on session. Looking ahead, after-hours trading is quiet, with S&P five hundred, Nasdaq, and Dow futures essentially flat and showing no meaningful directional drift from today's cash close. Among the megacaps, Alphabet climbed one point five four percent, giving back about zero point two percent in after-hours. Tesla gained one point seven eight percent, continuing higher in after-hours. Nvidia, however, was essentially flat, down zero point two two percent, a notable move given the broader semiconductor rally. Beyond megacaps, the semiconductor theme dominated. Micron Technology surged nineteen point two nine percent after a significant U B S upgrade, briefly crossing a one trillion dollar market capitalization. Micron is extending gains in after-hours. A S P Isotopes rallied twenty-four point eight six percent, also continuing higher after restarting Silicon-twenty-eight enrichment facilities. Aehr Test Systems gained fifteen point six eight percent, driven by strong A I test equipment demand. On the flip side, POET Technologies declined sharply by eight point five zero percent amidst shareholder lawsuits. In commodities, gold was little changed, but oil was a significant mover. Crude futures fell nearly three percent, with the U S O E T F dropping two point seven eight percent. This was attributed to progress in US-Iran peace talks, raising hopes for reduced tensions in the Strait of Hormuz and contributing to the overall risk-on sentiment. Today on Wall Street, we saw a tech-led record-setting day, with the S&P five hundred and Nasdaq finishing notably higher. This strong US close should provide a positive tailwind for Asian markets. While the Nikkei two hundred twenty-five saw a slight pullback in its previous session, Nikkei futures are currently trading higher, suggesting a modestly firmer tone for tomorrow's open. However, Hang Seng futures are showing some after-hours softening compared to its underlying index close. Looking at macro themes, central banks remain a focus, with the Federal Reserve flagging ongoing inflation risks. US inflation data showed C P I at three point eight percent and P P I at six point zero percent last week. Geopolitical tensions in the Middle East continue to affect sentiment. For tomorrow, watch for key earnings announcements from companies like Zscaler, Pinduoduo, and Salesforce. Investors will continue to focus on A I spending, energy inflation risks, and Federal Reserve signals. That's your market wrap for today. This has been a 7 Horns AI production.
