You're listening to seven horns a i — your a i powered market update. Today is Tuesday, September eighth, twenty twenty-six, and the New York market has officially closed. It was a risk-off session on Wall Street as blue chips led the market lower, while tech showed relative resilience. Major indices opened mixed, but selling pressure built steadily through midday, pushing the Dow down nearly five hundred and seventy points at its lows, before closing near the bottom of the range. By the bell, the S&P five hundred shed zero point five eight percent to close at seventy-six hundred and seventy-four. The Dow Jones Industrial Average dropped one point one eight percent to fifty-two thousand seven hundred and eighty-six, marking its steepest one-day decline in over two weeks. Meanwhile, the Nasdaq Composite held up much better, slipping just zero point three one percent to end at twenty-six thousand four hundred and twenty-four. Looking at the after-hours action, the market is essentially flat and in line with the close. S&P five hundred and Nasdaq tracker ETFs are down less than a tenth of a percent, suggesting an orderly and stable handoff heading into tomorrow. In megacap tech, Tesla was the standout performer, rallying three point nine eight percent despite the broader market decline. On the downside, Nvidia fell two point zero one percent, while Apple and Microsoft both drifted lower, declining one point one seven percent and one point one five percent respectively. Outside of tech, the big story of the day was in healthcare. Amgen plummeted ten point zero eight percent, suffering its steepest one-day drop in about twenty-six years. This massive slide came after Novartis announced that its experimental heart drug failed a phase three trial, which cast a shadow over Amgen's competing treatment. E-commerce giant Shopify also fell sharply, declining seven point fifty-seven percent on valuation concerns. On the positive side, artificial intelligence infrastructure names had a stellar day. Lumentum surged eleven point zero four percent, Semtech gained nine point ninety-six percent, and Bloom Energy rallied nine point sixty-three percent. Turning to international markets, today's risk-off tone on Wall Street is expected to act as a headwind for the upcoming Asian session. Both major Asian exchange-traded funds closed lower in U.S. trading today, with the Japan fund down zero point three three percent and the China large-cap fund sliding two point forty-five percent. This weakness, combined with the slide in New York, may weigh on sentiment as Tokyo opens, though a mild positive tick in Hang Seng after-hours futures, up zero point three two percent, could help limit the broader selling pressure. The primary macro catalyst driving today's pressure was a major spike in oil prices. Brent crude flirted with the one hundred dollar mark, settling near ninety-eight dollars a barrel amid geopolitical tensions in the Middle East. This spike revived inflation anxieties, sending the ten-year Treasury yield near four point eight zero percent. Investors are staying cautious as we await key inflation data later this week, with the producer price index scheduled for Thursday, September tenth, and the consumer price index on Friday, September eleventh. These releases will be critical as the Federal Reserve meets next week to debate its first rate hike since twenty twenty-three. Finally, keep an eye on Bloom Energy, which will be added to the S&P five hundred on September twenty-first. That's your market wrap for today. This has been a seven horns a i production.
