You're listening to Seven Horns AI — your AI-powered market update. Happy Sunday, September twentieth, twenty twenty-six. With the markets closed for the weekend, we're looking back at how the week wrapped up and what to watch as we head into tomorrow's opening bell. Friday's session ended on a mixed, essentially flat note as investors digested a monumental week of macroeconomic developments. The S&P five hundred edged up zero point one seven percent, closing at seventy-six hundred and fifty-one, while the tech-heavy Nasdaq Composite gained zero point three nine percent to finish at twenty-six thousand five hundred twenty-three. Meanwhile, the Dow Jones Industrial Average slipped fractionally, losing zero point one eight percent to end the week at fifty-one thousand six hundred eighty-three. The big catalyst of the week was the Federal Reserve raising its benchmark interest rate by twenty-five basis points to a range of three point seven five to four percent—its first rate hike in over three years. We also saw a significant slide in oil, with West Texas Intermediate crude futures falling five point seven two percent to ninety-six dollars and eight cents a barrel as supply fears receded. In individual stocks, we saw double-digit gains in crypto-linked and semiconductor names during Friday's session. MicroStrategy gained sixteen point three nine percent and Coinbase rose eleven point six six percent, buoyed by Bitcoin reclaiming the eighty thousand dollar mark. SanDisk also gained ten point nine nine percent on news of its upcoming inclusion in the S&P one hundred. On the flip side, Qualcomm declined five point eight two percent, and Meta fell two point four three percent. In corporate news, the most symbolic headline of the week came from Berkshire Hathaway, where Warren Buffett officially stepped down as chairman, transitioning to chairman emeritus. His son, Howard Buffett, is set to become board chairman, while Greg Abel remains chief executive officer. Although the market had largely anticipated this succession, the end of the Buffett era marks a historic shift for quality and value investing. Looking ahead to the coming week, investors are preparing for crucial inflation data and corporate earnings. On Tuesday, September twenty-second, we'll get the key personal consumption expenditures inflation reading, which will give us a fresh look at whether the Fed's latest hike is cooling price pressures. On Thursday, September twenty-fourth, Costco will report its latest earnings, offering a key indicator of consumer health. Finally, watch out for memory-chip leader Micron, reporting on Wednesday, September thirtieth. Heading into tomorrow's session, Nasdaq futures are pointing modestly higher, up zero point five nine percent, while S&P futures are flat, up zero point zero seven percent, and Dow futures are down zero point two seven percent. Because Asian markets closed modestly lower on Friday tracking earlier Wall Street weakness, tonight's Tokyo and Hong Kong opens should expect some stabilization given the resilient tone in US tech and tech futures. That's your weekend market review from Seven Horns AI. Enjoy the rest of your weekend, and we'll see you when the bell rings Monday. Visit sevenhorns.ai for more insights.
