Hey everyone, Hirokichi here.
U.S. stocks closed higher across the board on Friday, September 25, with the Dow jumping 478 points. A pullback in oil prices and a pause in the relentless climb in Treasury yields gave investors some relief. Let’s dig into what drove the day and which stocks were in the spotlight.
All three indexes rebound — the Dow gains 478 points
Let’s start with the headline numbers.
| Index | Close | Change | % Change |
|---|---|---|---|
| Dow Jones | 51,828.62 | +478.64 | +0.93% |
| S&P 500 | 7,743.41 | +39.28 | +0.51% |
| Nasdaq Composite | 27,068.72 | +129.34 | +0.48% |
The Dow had been on a three-day losing streak through September 24, so Friday’s bounce was a welcome change. For the week, the Dow added 0.3%, the S&P 500 gained 1.2%, and the Nasdaq climbed 2.1% — all three indexes finished in the green for the week (source: AP, “How major US stock indexes fared Friday 9/25/2026”). In my view, the Dow snapping its three-week losing streak is a small but meaningful sign that investor nerves are settling down a bit.
What moved the market: falling oil and a pause in yields
The biggest driver behind Friday’s rebound was a drop in oil prices. WTI crude fell 2.33% to $92.41 a barrel, and Brent crude slipped below $100 (source: Yahoo Finance). Easing worries over Middle East tensions helped, and with energy costs looking less threatening, the broader market breathed a sigh of relief.
The second big story is long-term interest rates. The 10-year Treasury yield had climbed to around 5.2% this week (reports put it at 5.18%–5.22%), the highest level since 2007 — roughly two decades. Strong economic data, including a September services PMI (Purchasing Managers’ Index, a gauge of business sentiment) reading of 58.7, the best in about five years, along with hawkish comments from several Fed (Federal Reserve, the U.S. central bank) officials, had been pushing yields higher. On Friday, that climb paused, which was a tailwind for stocks. That said, when the University of Michigan’s final consumer sentiment reading came in above expectations, yields briefly ticked back up and weighed on stocks — so it wasn’t a completely smooth ride, which is worth keeping in mind.
Stocks in the spotlight
Beyond the indexes, individual stocks told their own stories on Friday. Here’s a look at four notable names.
Meta (META): down 3.14% as the AI rally cools off
Meta Platforms fell 3.14%. The stock had climbed nearly 16% over the week following the launch of its new AI (artificial intelligence) feature “Muse,” but Friday saw investors lock in profits. At its annual Meta Connect event, the company unveiled new smart glasses and VR hardware, but that also drew attention to the massive capital spending on data centers and custom silicon needed to support its AI roadmap — raising concerns about near-term free cash flow (cash left over after covering operating and capital expenses). Reports of CEO Mark Zuckerberg selling shares added to the pressure, and technical indicators like RSI (Relative Strength Index, a measure of whether a stock is overbought or oversold) were already flashing overbought signals. In my view, this looks like a classic “sell the good news” pattern after several very strong weeks.
Akamai (AKAM): up 8.78% on a major AI cloud deal
Akamai Technologies jumped 8.78% after announcing a cloud services agreement worth more than $7 billion with AI developer Anthropic. Akamai, historically known for its CDN (content delivery network) business, has been pivoting toward cloud and security services, and this deal is a strong sign that its bet on AI infrastructure demand is paying off — it meaningfully boosts revenue visibility for years to come.
Datadog (DDOG): up 7.28% ahead of earnings
Datadog rose 7.28% on what looks like anticipatory buying ahead of its upcoming earnings report. There wasn’t a specific new catalyst behind the move — it appears investors were positioning for good numbers. Worth noting: if the actual results disappoint, there’s a real risk of a reversal.
Zscaler (ZS): down 8.64% on a leadership change
Zscaler dropped 8.64% after news broke of a change in its Chief Revenue Officer (the executive overseeing sales and revenue strategy). For growth stocks, a shakeup in the sales leadership often worries investors more than the underlying numbers do, since it raises questions about whether growth momentum can be sustained — and that’s exactly what played out here.
Sector moves: technology leads the way
Looking at S&P 500 sectors, Friday was a mixed session — only 3 of the 11 sectors closed higher, while 8 finished lower.
Technology led the gainers at +0.83%, powered by continued optimism around AI. Industrials also held up well, adding +0.45%. On the downside, Communication Services was the worst performer at -1.04%, largely dragged down by Meta’s decline. Energy fell -0.93% as oil prices slid, and Real Estate slipped -0.41% as elevated rates continued to weigh on the sector. Popular ETFs among Japanese retail investors, like VOO (Vanguard S&P 500 ETF) and QQQ (Invesco QQQ, tracking the Nasdaq 100), moved in line with the indexes, each gaining roughly 0.5%.
What to watch in Japan today
With U.S. stocks closing higher and finishing the week in positive territory, here are three things worth watching in the Japanese market today.
(1) A broad-based U.S. rally, with all three indexes ending the week higher, should be a supportive backdrop for Tokyo’s open.
(2) That said, the 10-year Treasury yield remains at its highest level since 2007, so rate-sensitive names (real estate, growth stocks, and similar) may continue to face headwinds. Worth watching alongside Japan’s own long-term rates and Bank of Japan policy signals.
(3) On individual names, Meta’s pullback could spill over into short-term profit-taking on high-flying AI stocks. On the other hand, if capital keeps flowing into AI infrastructure plays like Akamai, that could also lift interest in Japan’s data center and semiconductor-related names.
Let’s keep at it, slow and steady. Have a good day!
