NYSE Rollercoaster: Fed Caution Halts Tech Rally, Mega-Deals & Gold Spike in Wild 48 Hours

NYSE News Roundup for September 23–24, 2025

Record Run Stalls: Wall Street’s AI-driven rally snapped on Sept. 23 as major indexes fell (Nasdaq –0.95%, S&P 500 –0.6%, Dow –0.2%) after Fed Chair Jerome Powell warned of “no risk-free path” on rates and deemed stocks “fairly highly valued” ^[1] ^[2].
Tech Leads Pullback: High-fliers like Nvidia plunged ~3% after hitting records, erasing Monday’s gains ^[3]. Oracle sank 4% post-CEO shakeup, while Big Tech names from Amazon to Apple slipped ^[4] ^[5].
Safe Havens Surge: Investors hedged risk amid Fed jitters – gold hit fresh all-time highs near $3,764/oz ^[6] and 10-year Treasury yields dipped to ~4.10% as caution set in ^[7]. Oil prices jumped on supply snags (Brent ~$67.8, +0.3%) fueling energy stocks ^[8] ^[9].
Biggest Gainers & Losers: Halliburton (+7.3%) led S&P 500 advancers on rising crude ^[10], with McKesson (+6.4%) rallying after boosting profit forecasts ^[11]. In contrast, Generac (-10%) plunged despite upbeat analyst views ^[12], Vistra (-6.3%) fell on a downgrade ^[13], and Regeneron (-4.7%) slid after a legal setback for its top drug ^[14].
Earnings Spark & AI Boom: Micron’s blockbuster earnings (record $11.3B Q4 revenue, +46% YoY) and upbeat AI-driven outlook sent its stock up ~3% after hours ^[15] ^[16], lifting Nasdaq futures early Sept. 24 ^[17]. CEO Sanjay Mehrotra touted “all-time highs” in data-center sales and “strong momentum” into 2026 ^[18].
Deal Frenzy and M&A Moves: Media merger buzz intensified as Paramount Skydance (recent buyer of Paramount Global) reportedly eyes a bid for Warner Bros. Discovery in a mostly cash deal backed by the Ellisons ^[19]. Earlier this month WBD shares surged 30% on the takeover rumor ^[20]. In real estate, Compass struck an all-stock $1.6 B acquisition of Anywhere Real Estate at an 84% premium, creating a $10 B brokerage giant with 340,000 agents worldwide ^[21] ^[22]. Meanwhile, the largest rail union endorsed Union Pacific’s proposed $85 B mega-merger with Norfolk Southern – a deal promising coast-to-coast rail efficiency but facing a lengthy 2-year review and opposition from some shippers and unions ^[23].
Fed Policy in Focus: The Fed’s first rate cut of 2025 (last week) has markets betting on more – futures put a 94% chance on another quarter-point cut in October ^[24]. Yet Powell’s Rhode Island speech offered “few hints”on timing ^[25] and stressed a delicate balance between still-high inflation and a cooling job market. “If rates are cut too aggressively, inflation could rise back up,” Powell cautioned, emphasizing a data-driven approach ^[26] ^[27]. Vice Chair Michelle Bowman echoed a dovish stance, suggesting faster cuts may be needed to aid employment, even as other Fed officials urged vigilance on inflation ^[28].
Macroeconomic Mixed Signals: Fresh data painted a nuanced picture. U.S. PMI surveys for September came in weaker than expected, showing growth in manufacturing and services losing steam ^[29]. The OECD raised its U.S. growth forecast for 2025 to 1.8% (from 1.6%), citing an AI investment boom, but warned that higher tariffs and lower net immigration will slow 2026 growth to just 1.5% ^[30] ^[31]. Notably, President Trump’s recent “reciprocal” tariffs pushed the average U.S. tariff rate to ~19.5% – the highest since 1933 – a headwind for growth ^[32]. Upcoming data could sway sentiment: final Q2 GDP and the Fed’s preferred PCE inflation gauge are due this week, with core price growth still well above target ^[33] ^[34].
Geopolitical Clouds: Global events kept investors on edge. In a combative U.N. speech on Sept. 23, President Donald Trump threatened “a very strong round of powerful tariffs” against Russia if it doesn’t end its war in Ukraine, urging European allies to join any such measures ^[35]. He also dismissed climate change as a “con job” and criticized allies on migration, underscoring policy shifts that could impact energy and defense sectors ^[36] ^[37]. Meanwhile, Washington inched toward a potential government shutdown as budget talks faltered; with only days left in the fiscal year, bipartisan negotiations stalled and Trump scrapped a meeting with Democrats, heightening fiscal uncertainty ^[38] ^[39]. Ongoing wars – from Ukraine to a renewed Gaza conflict – added to the cautious mood, driving haven flows and keeping volatility elevated.
Expert Outlook – Caution and Euphoria: Market veterans are divided on what’s next. “With this being the third year of double-digit returns for the S&P 500, there needs to be another strong catalyst to move stocks materially higher – and right now, it is not clear what that catalyst can be,” warns Oliver Pursche of Wealthspire Advisors ^[40]. The broad rally has been remarkably resilient, fueled by hopes of Fed easing; “markets are sanguine in this ‘everything rally,’ awaiting more evidence that further Fed easing will steer the economy away from any hard landings,” noted BNY strategist Bob Savage ^[41]. Yet tail-risk experts urge vigilance: Mark Spitznagel of Universa – a hedge fund famed for profiting from market crashes – believes euphoria may carry the S&P 500 20% higher to ~8,000 before “a historic crash” hits. “I do expect an 80% crash…but only after a massive, euphoric blow-off rally,” Spitznagel says, likening the setup to 1929 ^[42] ^[43]. In the near term, many on Wall Street will be watching the upcoming Q3 earnings season and Washington’s next moves. If inflation can continue to ease and a government shutdown is averted, some analysts see the rally regaining steam into year-end – but any disappointment could test the market’s record valuations. As one strategist summed up, “the bull market’s next leg may depend on whether the Fed and economy stick the soft landing investors are betting on” – a high-stakes balance that will define the NYSE’s trajectory after this tumultuous week.
