The Week in Review

This was a week where the headline number told you almost nothing.

The S&P finished essentially flat — down seven points across five sessions that included the first Federal Reserve rate hike since 2023. Underneath that calm, the market did a great deal of repricing.

Monday started with an unusual catalyst. Semiconductor and AI infrastructure names sold off on public calls from the CEOs of Anthropic and OpenAI to slow the pace of frontier model development. That is a new kind of headline risk for the AI complex — not a demand problem or a financing problem, but the builders themselves suggesting the pace should moderate.

Wednesday brought the Fed. The committee raised the federal funds target range by 25 basis points to 3.75%–4.00%, its first increase in more than three years, on a unanimous 12-0 vote. Kevin Warsh arrived at the Fed with a roadmap to lower borrowing costs; less than four months in, he has pulled the trigger on a hike instead.

The decision itself was expected. The Summary of Economic Projections was not. In June, the median policymaker projected the funds rate falling to 3.6% by the end of 2027. The September median showed 4.1% — identical to the 2026 median, implying no net easing at all across the entire forecast horizon. Every year shifted up by roughly 0.3 percentage points.

The distribution was more hawkish than the median alone suggests. Of the 18 officials submitting projections, 12 expected exactly one more hike in 2026, four expected two more, and only two expected none — meaning 16 of 18 see at least one additional increase this year. In June, nine members had projected at least one hike and one dot still showed a cut. That cut dot is gone.

The nuance worth carrying forward: only eight dots project a further hike in 2027. So this reads less like the start of an extended tightening cycle and more like one more hike, then a long hold. That is the distinction between a decision shock and a duration shock, and it is what actually repriced. Markets had the 25 basis points. What they had to absorb was how long restrictive policy might last.

Also worth noting: Warsh declined to submit a dot, as he did in June. The 4.1% median belongs to the participating policymakers, not to the Chair.

Stocks fell Wednesday on the release. Thursday they came back, with technology leading and both the S&P and Nasdaq reclaiming their 50-day moving averages after a single day below. The Bank of England held at 3.75% the same day. Friday was quarterly expiration — quad witching — and the rally stalled as global yields bounced again.

Two data points deserve more attention than they got. August retail sales rose 6.0% year over year against a 4.7% forecast, and import prices ran 7.0% against 6.4% expected. Both landed the morning of the Fed decision, and both almost certainly fed the hawkish shift in the dots.

And the internals are deteriorating in a way the index masks. Transports, small caps, Industrials and Consumer Discretionary have now fallen five consecutive weeks. XLY is down six straight. XLP, XLI and XLRE are down five; XLB four. Meanwhile U.S. equity funds recorded $31.44 billion of net redemptions in the week to September 18, a fourth straight week of outflows following $32 billion the week before, and the NAAIM active-manager exposure index dropped from above 100 to below 75. Money is leaving and professionals are de-risking while the S&P sits three points from unchanged.

Market pricing as of Friday morning: 90% odds of another hike by the December 9 meeting, with a 55% chance it arrives as soon as October 28.

Weekly Market Scorecard — Week Ending September 18, 2026

QQQ and IWM are derived from their underlying indexes, which are exact: Nasdaq Composite 26,333.04 → 26,522 (+0.72%); Russell 2000 2,903.94 → 2,860 (-1.51%). Other closes: Dow 51,680 (-1.70% on the week), 2-year 4.74%, 20-year 5.39%, 10-year near 4.95–5.00%. Friday itself was mixed: Dow -0.19%, SPX +0.16%, Nasdaq +0.39%, Russell -0.50%.

SPX / SPY

The index reclaimed its 50-day moving average at 7,615 on Thursday after three sessions below it. That level is now the line that matters — holding above it keeps the short-term structure intact, losing it again opens the door lower. Support: 7,615 (50-day), then 7,570–7,580, then 7,500, then the July 29 low at 7,316. Resistance: 7,700 first, then 7,747, then the record at 7,798.99 from August 13. The 200-day sits far below at 7,178.86 — the long-term uptrend is undamaged.

QQQ

Around 722.8, up roughly 0.72%, with the Nasdaq Composite at 26,522. Large-cap technology was the only thing holding the index up this week. It carries the balance sheets to absorb a 4% funds rate, which is precisely why it outperformed while everything financed with floating-rate debt was sold.

IWM

Around 284.3, down roughly 1.51%, with the Russell 2000 at 2,860 — making lower lows and now well below the 3,000 level it held all summer. Small caps trade on duration, and the dot plot just extended duration by two years.

Next Week's Economic Calendar — September 21 to 25

Monday September 21 — Chicago Fed National Activity Index (Aug), 8:30 AM ET.

Tuesday September 22 — Richmond Fed Manufacturing Index (Sep), 10:00 AM ET; Treasury sells $78 billion in 2-year notes, 1:00 PM ET.

Wednesday September 23 — S&P Global Flash PMIs (Manufacturing, Services, Composite), 9:45 AM ET; Treasury sells $70 billion in 5-year notes, 1:00 PM ET; MBA Mortgage Applications; EIA inventories.

Thursday September 24 — Initial and continuing jobless claims, 8:30 AM ET; Q2 Current Account Balance; New Home Sales (Aug), 10:00 AM ET; Kansas City Fed Manufacturing, 11:00 AM ET; Treasury sells $44 billion in 7-year notes, 1:00 PM ET.

Friday September 25 — Durable Goods Orders (Aug) and ex-transportation, 8:30 AM ET; University of Michigan Sentiment, final (Sep) plus 1-year and 5-year inflation expectations, 10:00 AM ET.

Key watch: the Treasury auctions, and they deserve the top slot. $192 billion of coupon supply across Tuesday, Wednesday and Thursday — $78B in 2-years, $70B in 5-years, $44B in 7-years — arriving in the first full week after the Fed signaled at least one more hike and removed any expectation of easing through 2027. The 2-year already closed the week at 4.74%. Watch the bid-to-cover ratios and whether the auctions tail. Weak demand pushes yields higher across the curve, and higher yields are precisely what has been grinding down small caps, Industrials and Consumer Discretionary for five straight weeks.

Friday's final Michigan reading is the secondary tell. The preliminary September number was 47.8, down 7.5% from August and the second-lowest reading on record, with one-year inflation expectations at 4.6%. If the final confirms that, the Fed is hiking into a consumer already reeling from fuel prices. Note there is no CPI, no PCE and no payrolls this week — Wednesday's flash PMIs are the only real read on September activity.

Major Earnings This Week

A light calendar, and it skews consumer — which makes it more useful than it looks given what the sector data is doing.

Tuesday — AutoZone (AZO), MillerKnoll (MLKN), Thor Industries (THO) before the open; KB Home (KBH) and Worthington (WOR) after the close.

Wednesday — General Mills (GIS), Cintas (CTAS), Paychex (PAYX), Cracker Barrel (CBRL) before the open; Stitch Fix (SFIX) after.

Thursday — Darden Restaurants (DRI) before the open, consensus around $2.05 EPS on revenue near $3.2 billion; BlackBerry (BB); Costco (COST) after the close.

Key watch: Costco Thursday after the close. Consumer Discretionary has fallen six consecutive weeks and Michigan sentiment printed its second-lowest reading on record, yet August retail sales came in at 6.0% year over year against a 4.7% forecast. Those two things cannot both continue. Costco's membership renewal rates and traffic-versus-ticket split are the cleanest window into whether households are genuinely spending or simply paying more for the same basket. Darden is the discretionary read — restaurant same-store sales soften early when budgets tighten. Thor and KB Home cover the big-ticket, credit-financed end: RVs and homes are exactly what stops selling when the 2-year is at 4.74% and the Fed has just said there is no relief coming through 2027.

30-Day Market Outlook

Overall bias: Neutral on the index, negative on breadth. The S&P at 7,650 is roughly 2% below its August record and finished the week essentially unchanged. That headline is hiding a market where most sectors have been falling for more than a month.

Macro narrative: The September meeting resolved one question and opened a harder one. Whether the Fed would move is settled — it moved, unanimously, and 16 of 18 officials expect at least one more this year. The new question is how long rates stay there, and the dots answered it in a way the market had not priced: no net easing through 2027.

That reprices duration, and duration is what small caps, Industrials, Transports and Consumer Discretionary trade on. Those four groups have fallen five straight weeks while the Nasdaq has risen. The index is being carried by a narrow band of large-cap technology with the balance sheets to absorb a 4% funds rate. Everything financed with floating-rate debt is being sold. Four consecutive weeks of equity fund outflows totaling more than $60 billion, and active-manager exposure falling from above 100 to below 75, say professionals are acting on that view rather than just talking about it.

The counterweight is real: Thursday's rebound showed genuine appetite to look past higher-for-longer and back toward the AI earnings story, and corporate profits are still growing. But the market is now paying for that growth with a higher discount rate and no prospect of relief for two years.

Primary risk: Weak Treasury auctions Tuesday through Thursday. $192 billion of supply into a hawkish Fed is a real test, and a tail on the 7-year in particular would send long yields higher and hit exactly the cohort that has been bleeding for five weeks. With the S&P only just back above its 50-day, there is not much cushion.

Secondary risk: The October 28 meeting. Markets price a 55% chance of a hike there and 90% by December 9. Any data between now and then that firms inflation — particularly energy — pulls that forward.

What would change the picture: Strong auction demand plus a soft final Michigan print. That combination would let the long end settle, and the groups that have been punished for five weeks — small caps, Industrials, Discretionary — are where the snapback would be sharpest. Watch the 2-year: a move back below 4.60% would be the first sign the duration shock is being digested.
