You're listening to Seven Horns A I — your A I-powered market update. Today is Sunday, July nineteenth, twenty twenty-six, and with the markets closed for the weekend, we are bringing you a review of a highly volatile week of trading and a look at what to watch in the week ahead. Wall Street finished the week on a down note on Friday. The sell-off was catalyzed by a dramatic overnight plunge in Japanese equities that rippled across global markets. The tech-heavy Nasdaq Composite led the declines on Friday, falling one point four percent to close at twenty-five thousand five hundred twenty. The S and P five hundred declined about one percent, ending the session at seventy-four hundred fifty-eight and closing below its fifty-day moving average for the first time in weeks. Meanwhile, the Dow Jones Industrial Average dropped zero point seven seven percent to close at fifty-two thousand one hundred forty-six. Friday's drop was shaped by an overnight shock out of Tokyo, where the Nikkei two hundred twenty-five suffered a massive intraday plunge of over four thousand one hundred points. Despite the headline losses, we did see an orderly rotation into defensive sectors, with consumer staples gaining two point nine percent on Friday. Oil prices also jumped, with crude oil rising nearly four percent on Friday and extending those gains by over three and a half percent on Sunday evening due to escalating tensions between the United States and Iran. In weekend news, geopolitical and trade tensions remain in focus. The Trump administration announced twenty-five percent tariffs on Brazilian goods, including furniture, ethanol, and machinery, while also threatening Canada with tariff increases over drifting wildfire smoke. In company news, Apple was the lone holdout among megacaps, closing essentially flat as defensive money sought safety. The rest of tech did not fare as well, with Meta Platforms sliding two point seven nine percent, Tesla dropping two point six one percent, and Nvidia falling two point two one percent. Beyond the megacaps, Intuitive Surgical dropped over fourteen percent. Although the company beat second-quarter earnings estimates, its U.S. procedure growth slowed to twelve percent, which sparked worries about elective surgery trends. On the positive side, Seagate Technology defied the broader chip rout, rallying five point six six percent following a Wells Fargo upgrade and strong demand for artificial intelligence data-center storage. Looking ahead, Friday's weak close in New York could set a cautious tone for the Asian markets when they open on Monday. This negative sentiment is already showing up in Sunday futures, which are pointing lower. S and P five hundred futures are down about one point zero six percent, while Nasdaq one hundred futures have slid one point five five percent. This upcoming week will also be a major test for the market with a heavy slate of megacap earnings, including Alphabet on Tuesday, followed by Tesla, I B M, and Texas Instruments on Wednesday, and Intel on Thursday. We will also be watching the Federal Reserve, with Dallas Fed President Lorie Logan hinting that modestly higher rates are still needed to cool inflation ahead of the central bank's policy decision on July twenty-ninth.
