4. Key events and the market's logic

• Buffett steps down as Berkshire Hathaway chairman; his son Howard succeeds him

  In his Friday letter to shareholders, the 96-year-old Buffett announced he would immediately move to chairman emeritus while remaining a director, ending a 56-year chairmanship that began in 1970. His son Howard Buffett, a director since 1993, takes over as chairman under the long-standing succession plan, with Sue Decker continuing as lead independent director. Greg Abel has been chief executive since early 2026, with the split described as Abel running the company and Howard safeguarding the culture and values. Berkshire's Class B shares closed up 0.11% at 509.77 dollars, while the Class A shares at 763,600.01 dollars were little changed — a muted reaction that says the transition was fully anticipated. The real open question is the one the letter cannot answer: how more than 360 billion dollars of cash gets deployed in an era without Buffett in the chairman's seat.
• The first full session after the hike: the 10-year Treasury yield back at 5%

  The Fed hiked 25 basis points on Wednesday, September 16 — its first increase in more than three years. Yields pushed higher again on Friday: the 10-year closed at 4.9961%, up 6.57bp on the day, while the 2-year finished at 4.7433%, up 7.92bp and close to its highest since late April 2024. According to CME FedWatch, futures now price a 55% probability of another 25 basis point hike at the end of October and a 90% probability of further tightening before December. Kansas City Fed President Schmid said the central bank still has work to do on inflation and that this week's hike was a step in that direction.
• Apple launches the iPhone 18 Pro with a 100 dollar price increase

  The company attributed the increase to higher memory costs, with channel feedback pointing to delivery waits of about three weeks. The stock closed down 0.26% on the day. Cost inflation flowing through to end pricing is itself a side confirmation of the storage upcycle — on the same day SanDisk rose 10.99% and Micron rose 3.92%, upstream on the very same cost curve.
• Wells Fargo cuts Netflix to underweight

  Target lowered from 80 dollars to 57 dollars. Netflix fell 4.67% on the day and dragged the entire communication services sector with it.
• Xenon Pharmaceuticals halts enrollment in a Phase 3 trial, shares slump

  After reviewing neuropsychiatric adverse events, the company paused enrollment in two studies covering major depressive disorder and bipolar disorder, and filed the same day for a focal-onset seizure indication. Deutsche Bank cut the stock to hold and lowered its target from 90 dollars to 46 dollars. XENE fell 30.69%, the worst performer in the S&P 500 on the day.
• Three sector-level chain reactions to the downside

  Nuclear: UBS cut NuScale Power to sell with its target down from 10 dollars to 6 dollars; the stock fell 8.52% on the day, with OKLO down 4.16% and Centrus down 3.08%.
  Sports betting: a second straight down session on intensifying prediction-market competition, with Rush Street down 7.72%, PENN down 5.78%, DraftKings down 3.20% and Flutter down 3.18%.
  Cybersecurity: pulling back after gaining 8% to 14% this week, with Okta down 4.03%, CrowdStrike down 3.28% and Palo Alto down 3.06%.
• Quarterly options and futures expiration

  September 18 was the third Friday of the quarter, a quarterly derivatives expiration date that typically inflates volume and late-day volatility. That technical layer needs to be priced into any read of intraday moves.
• All three major central bank decisions landed this week

  The Fed hiked 25 basis points, the Bank of England held its benchmark rate at 3.75% for a sixth consecutive meeting, and the Bank of Japan raised rates. All three decisions are in the price; Friday's tape was the market answering what it does with them.

5. Cross-asset: crude and rates moved in opposite directions

6. Takeaways

1. This is not a market afraid of higher rates; it is a market that has accepted them
   Utilities, real estate and materials — the three most rate-sensitive sectors — fell between 0.94% and 1.40%, which is not panic. Technology rose 0.81%, industrials 0.47%, and the VIX closed at 14.81 and kept falling. The structure looks like sector rotation rather than de-risking. What is actually being priced out is not the question of whether rates go higher, but which assets cannot carry higher rates.
2. The semiconductor strength was a catch-up trade, not a new narrative
   Gains were concentrated in storage and optics (SanDisk +10.99%, Coherent +7.22%, Seagate +6.93%) while leaders such as Nvidia at +1.34% and TSMC at +1.03% moved modestly. Laggards leading usually means the move is driven by capital rebalancing, and its durability depends on the next round of AI data-center capex data. The one counter-example on the day was Supermicro at -3.12%, which shows money is making choices even within semis.
3. Risk appetite has not disappeared, it has changed lanes
   The Russell 2000 fell 0.50% on the same day bitcoin rose about 6% and roughly 238 million dollars of shorts were liquidated. Money willing to take risk is avoiding rate-sensitive assets and moving toward directions not directly tied to the discount rate. How stable that preference structure proves to be is the key input for judging the depth of any pullback — if small caps keep losing funding while crypto stays strong, this is repositioning rather than risk aversion.
4. The next variable to watch is whether the 10-year yield can hold 5%
   It closed at 4.9961%, sitting right on the line. Further upside would transmit first to utilities and real estate, then to richly valued growth, and finally to small caps; a retreat below 4.90% would temporarily break that chain. The Dow's third straight weekly decline, by contrast, is a result rather than a cause — the Dow's composition skews cyclical and defensive, the least rate-sensitive end of the market, so its leading decline says the drag is coming from somewhere else.
