Inflation Relief Rally Exposes Cyclicals Weakness While Energy Runs Ahead

Week 2 of September 2026 — Weekly Market Analysis

This Week's Theme: "An inflation‑relief bounce hiding a quiet stress test under the surface"

For the week ending September 13, 2026, U.S. equities delivered a choppy pattern: weakness early, relief rally late. Mid‑week, a jump in oil prices and renewed inflation fears weighed on stocks, but by Friday markets bounced back after inflation data came in close to expectations and oil prices eased off their recent spike.(apnews.com)

Zooming out over the last 10 trading days, though, the picture is less cheerful: only 1 of 11 sectors is positive, and that is Energy. Most others are down between 2–5%, indicating a market that is testing the durability of this year’s rally rather than broadening it.

At the same time, over 120 days (about six months) 10 of 11 sectors are still positive, with Technology up more than 38%. So, this looks more like a digesting‑gains phase than the start of a full‑blown bear market.

Below we walk through sectors and key stocks, connecting the week’s moves to the real economy and to the longer‑term trends.

Sector Performance: Energy leads, cyclicals and rate‑sensitives lag

1. Energy: Refiners power a fundamentally driven rally

10D return: +3.08% (best of 11 sectors; only positive sector)
30D: +10.06%
120D: +11.47%
Trend model: Since August 10, the equal‑weight Energy portfolio is in a +7.87% up‑trend, following earlier summer pullbacks.

The face of this week’s strength was U.S. refiners:

Valero (VLO): +12.93%
Marathon Petroleum (MPC): +9.08%
Phillips 66 (PSX): +8.24%

With crude trading around $100 a barrel and refined product demand holding up, refiners are enjoying very strong crack spreads (refining margins). Recent coverage highlights that large U.S. energy names have reported sharply higher profits in 1H 2026, with Marathon, Valero, and Phillips 66 together generating over $12 billion in Q2 profits and returning a record amount of cash via dividends and buybacks.(cincodias.elpais.com)

Why it matters for the real economy

High refining margins help Energy investors, but they also mean higher gasoline and diesel prices, which feed into transportation costs and ultimately consumer prices.
Capacity constraints and maintenance issues on the refining side mean this is not just a crude oil story; bottlenecks in processing capacity give refiners extra pricing power.

For investors: Energy has been a middle‑of‑the‑pack performer over 6 months but has clearly accelerated over the last 30–60 days, supported by cash flows, dividends, and buybacks. As growth and tech names wobble, that income‑plus‑fundamentals profile is drawing in capital.

2. Technology: Short‑term wobble, still the 6‑month champion

10D: -2.06%
30D: +8.18%
120D: +38.29% (best of all sectors)
Trend model: After a powerful run into mid‑August, Tech has shifted into a mild -0.61% down regime from August 17.

In plain English: Tech has been the engine of the 2026 rally, but it’s now in a cool‑down phase where good news is no longer enough for every stock.

Notable gainers this week:

Skyworks (SWKS): +31.95%
Dell (DELL): +20.66%
HP (HPQ): +20.63%

Skyworks’ spike is tied to the pending merger between Skyworks and Qorvo, which would consolidate the RF chip market and improve pricing power with big smartphone and telecom equipment customers. Recent commentary notes that the combo is approaching final clearance and that both stocks jumped as investors priced in greater scale and bargaining power.(investors.skyworksinc.com)

On the flip side, Autodesk (ADSK) plunged about 21.5% over the period. The company actually reported revenue and EPS above the high end of guidance and raised its full‑year outlook, yet the stock dropped roughly 16–17% in the subsequent days as investors worried about valuation, AI‑driven competition for design tools, and the durability of growth in large enterprise deals.(ebs.publicnow.com)

So what does this tell us?

Tech is still where the long‑term growth stories live, but with the sector up nearly 40% in six months, markets have become selective and unforgiving.
Names perceived as clear winners in AI, RF, or infrastructure are rewarded; companies facing new AI competition or pricing pressure can sell off hard, even on good earnings.

3. Communication Services: Meta shines, sector slips

10D: -0.91%
30D: +4.35%
120D: +2.37%
Trend model: Since August 26, the sector is in a modest -2.35% down regime.

Big movers:

Meta (META): +13.39%
The Trade Desk (TTD): +6.56%
AppLovin (APP): +3.38%

Digital advertising and social platforms continue to benefit from improving ad budgets and strong monetization, but the broader sector includes legacy telecom and media names that remain under pressure from high capex needs, competition, and regulation.

Translation: Within Communication Services, the “attention economy” platforms are pulling ahead, while the more capital‑intensive or regulated parts of the sector act as a drag.

4. Financials: A soft pullback after a strong 6‑month run

10D: -2.27%
30D: -0.28%
120D: +18.76%
Trend model: Since September 3, the sector has shifted into a -3.30% down phase.

Financials have benefited from higher interest rates (better lending margins) and hopes for a soft landing, which explains the strong 120D performance. The recent drift lower likely reflects:

The sense that “soft landing” optimism is already in the price for many banks and insurers.
Attractive yields on short‑term cash and money‑market funds, which compete with financial stocks for investor capital.

Even so, some large banks outperformed over the last 10D:

Wells Fargo (WFC): +6.48%
Citigroup (C): +4.54%

This underscores a shift where large, well‑capitalized banks are being seen as relatively safer havens within the risk asset complex.

5. Healthcare: Solid over 6 months, shaken by idiosyncratic risk

10D: -3.50%
30D: +3.44%
120D: +19.06%
Trend model: Since September 3, Healthcare has entered a -4.38% down regime.

Healthcare lies at the intersection of defensive cash flows and innovation‑driven growth, which is why the sector has done well over 120 days. But this week it suffered from stock‑specific shocks.

The standout loser was The Cooper Companies (COO), down about 24.17%.

In prior quarters Cooper had already taken a sizable litigation‑related charge tied to a 2023 product recall at CooperSurgical, which hurt EPS.(investor.coopercos.com)
This time, investors reacted negatively to weaker results influenced by inventory destocking and the decision to retain the CooperSurgical business, rather than simplifying the portfolio. Recent notes describe the Q2 results as disappointing and point to the combination of margin pressure and ongoing legal and regulatory overhang.(benzinga.com)

Takeaway: Healthcare as a sector can look steady, but individual names can move like small tech stocks when product recalls, regulatory risk, or litigation come into play.

6. Consumer Cyclical, Industrials, Consumer Defensive: The cyclical “stress test”

Consumer Cyclical

10D: -4.53% (weakest of all sectors)
30D: -5.94%
120D: +2.10%
Trend model: Since August 25, the segment has been in a -6.92% drawdown.

Some individual names did well — Best Buy (+7.91%), eBay (+5.52%), Tesla (+2.94%) — but the sector overall is getting pushed around by higher financing costs and concerns about discretionary spending.

In simple terms: anything you can delay buying (cars, gadgets, furniture, trips) is vulnerable when interest rates stay high and households feel cost‑of‑living pressure.

Industrials

10D: -4.19%
30D: -4.21%
120D: +5.35%
Trend model: Since August 12, Industrials are in a -7.42% downtrend.

Industrials had run up on infrastructure spending and onshoring themes, so part of the recent weakness is positioning and profit‑taking. Deere (+8.61%) stands out as a relative winner on continued demand for agriculture and construction equipment.

Consumer Defensive

10D: -3.61%
30D: -2.39%
120D: +5.41%
Trend model: Since August 24, the sector has been in a -6.18% decline.

This group is usually considered “safe,” but higher rates and sticky food prices mean investors are questioning how much they’re willing to pay for stability.

Bunge (BG): +10.13%
Archer‑Daniels‑Midland (ADM): +9.94%

Both benefited from grain and agricultural commodity dynamics, but staples and big box retailers overall are seeing some valuation compression.

Big picture: Across these three cyclical sectors, markets are probing how resilient demand really is if high borrowing costs stick around longer than expected.

7. Utilities, Real Estate, Materials: When rates and regulation bite

Utilities

10D: -1.94%
30D: -5.31%
120D: -3.22% (the only sector negative over 120D)
Trend model: Utilities have been in a -4.70% down regime since July 31.

This week’s story was not about interest rates — it was about California wildfire legislation and liability.

Edison International (EIX): -23.63%
PG&E (PCG): -23.03%

California lawmakers passed wildfire bill SB 492 without key liability protections that utilities had been hoping for. As a result, investors reassessed the risk that future wildfires could once again impose multi‑billion‑dollar losses and legal claims on these companies. Reports highlighted that PCG fell about 19% and EIX nearly 20% in a single session, with multiple analysts cutting ratings or outlooks in the wake of the bill’s passage.(boursorama.com)

Why this is important beyond these two stocks:

Utilities are often viewed as bond‑like, safe yield plays. The California case is a reminder that they can be anything but safe when regulation and physical climate risk collide.
For income‑oriented investors, it underscores the need to look not just at dividend yield but also at legal and political risk, especially in high‑fire‑risk regions.

Real Estate

10D: -2.84%
30D: -4.85%
120D: +8.37%
Trend model: Since August 24, Real Estate is in a -4.79% decline.

Real estate investment trusts (REITs) are highly sensitive to long‑term interest rates, since higher yields make their dividends less relatively attractive and can pressure property values.

Tower REITs like American Tower (AMT +2.12%) and Crown Castle (CCI +1.29%) held up a bit better, as they are backed by data and mobile connectivity demand.
But office, retail, and more leveraged property owners remain under pressure from a combination of higher funding costs and changing work/shopping patterns.

Basic Materials

10D: -3.24%
30D: +0.55%
120D: +8.99%
Trend model: Since September 3, Materials have slipped into a -3.09% down regime.

Fertilizer and ag‑chem names such as CF (+6.77%) and Mosaic (+6.37%) bounced on commodity dynamics, but the sector as a whole is grappling with slower growth expectations and choppy metals/chemicals pricing.

Notable Movers: What’s behind the >5% swings?

Big winners

Skyworks (SWKS, +31.95%)
Surged on renewed optimism around the Skyworks–Qorvo RF chip merger and its implications for market structure and pricing power. Traders also highlighted strong short‑term moves tied to options activity around the deal and upcoming earnings.(investors.skyworksinc.com)
Refiners (VLO, MPC, PSX, +8–13%)
Benefited from crude near $100, tight refining capacity, and record cash returns after very strong Q2 results.(cincodias.elpais.com)
Deere (DE, +8.61%)
Rode ongoing demand for farming and construction equipment, and is being treated as a higher‑quality cyclical in a market that’s punishing weaker balance sheets.

Big losers

Cooper Companies (COO, -24.17%)
Hit by Q2 results that reflected inventory destocking and lingering issues in the CooperSurgical unit, which previously led to a litigation‑driven earnings hit. The company’s decision to keep the under‑pressure business rather than restructuring it disappointed investors.(investor.coopercos.com)
Autodesk (ADSK, -21.50%)
Dropped sharply even after an earnings beat and raised outlook, as investors questioned how sustainable its growth is in an AI‑disrupted design software landscape and balked at a still‑rich valuation.(ebs.publicnow.com)
Edison International (EIX) & PG&E (PCG, both around -23%)
Sold off after California’s SB 492 passed without the liability protections utilities wanted, leading to analyst downgrades and widespread concern that wildfire risk will continue to sit squarely on shareholders’ shoulders.(stockopedia.com)

What to Watch Next Week: Durability over headlines

Looking ahead, three themes will likely matter more than any one day’s price action:

The inflation and rate path
This week’s CPI print gave markets a near‑term sigh of relief, but Energy prices and shelter costs will determine whether that relief lasts. If higher‑for‑longer rates become the consensus again, expect more pressure on utilities, real estate, and high‑multiple growth stocks.
Can the Energy rally keep running?
If crude and product prices stay elevated and refining margins remain fat, Energy could continue to outperform as a cash‑flow‑rich, shareholder‑friendly haven. If oil backs off meaningfully, we may see profit‑taking after a strong 30‑day run.
Regulation and policy risk repricing
The California wildfire bill was a stark reminder that politics can move stock prices 20% in a day. Investors should keep an eye on:
- State and federal actions affecting utilities, healthcare pricing, and big tech antitrust.
- How ratings agencies and bond markets react to these shifts, which in turn affect companies’ cost of capital.

Bottom line

“This week’s inflation‑relief rally masked an ongoing stress test of which sectors truly have durable earnings and which are exposed to rates, regulation, and disruption.”

Energy is leading on the back of solid cash flows and shareholder returns.
Tech and Healthcare are still strong over 6 months, but stock‑picking has become critical, with big winners and losers coexisting in the same sector.
Utilities, Real Estate, and Consumer Cyclicals are where the market is asking the hardest questions about debt loads, regulatory risk, and the true strength of demand.

For longer‑term investors, the message is less about this week’s index moves and more about understanding the real‑world levers — rates, commodities, policy, and AI — that will separate the durable from the fragile as the 2026 cycle matures.
