Sector Rotation
The cycle playbook is only half right in this market
① Sector rotation is the idea that leadership changes with the economic cycle: consumer discretionary and financials in recovery, tech and industrials in expansion, energy and materials in the late phase, staples and utilities in recession.
② The past year's data matches that picture only halfway. Defensives lagging (utilities -0.6%, staples +4.3%) fits the theory — but energy (+44.4%) and tech (+39.7%) sitting first and second means the leaders of two different phases rose together.
③ So rather than trying to name the current phase, it's more useful to know how concentrated your portfolio already is by sector. The real value of the rotation framework is checking your exposure, not forecasting.
🔄 What sector rotation actually claims — the four-phase frame
Sector rotation starts from an observation: different industries lead in different phases of the economic cycle. Separately from whether the whole market rises or falls, the spread between sectors can be enormous. Over the past year alone, first place (energy, +44.4%) and last (utilities, -0.6%) were 45 percentage points apart.
The most widely used frame splits the cycle into four phases.
| Phase | Characteristics | Textbook leaders | The logic |
|---|---|---|---|
| Early (recovery) | Exiting recession, low rates, credit reopening | Consumer discretionary · Financials · Real estate | Rate-sensitive sectors react first |
| Mid (expansion) | Growth accelerating, capex rising | Technology · Industrials · Communications | The stretch where companies start spending |
| Late (slowdown) | Inflation pressure, rising rates, peak growth | Energy · Materials · Health care | Commodity prices and pricing power dominate |
| Recession | Demand contracts, earnings fall | Staples · Utilities · Health care | Whatever sells regardless of the economy |
The mechanism is the lag between rates and corporate spending. When rates fall, sectors that borrow to consume and build (discretionary, financials, real estate) revive first. As the economy heats up, equipment and software budgets shift the lead to tech and industrials. Overheating lifts commodity demand and prices, favouring energy and materials. And when it breaks, only what sells regardless of the cycle is left — electricity, groceries, medicine.
📊 What the last year actually did — all 11 sectors
That's the theory. Here's the record. Below are one-year returns for the SPDR sector ETFs representing the 11 GICS sectors, as of 2026-08-21. The benchmark, SPY, returned +18.7% over the same window.
| Rank | Sector | ETF | 1-year return | Max drawdown | Dividend yield |
|---|---|---|---|---|---|
| 1 | Energy | XLE | +44.4% | -14.9% | 2.55% |
| 2 | Technology | XLK | +39.7% | -13.6% | 0.45% |
| 3 | Health care | XLV | +26.4% | -10.6% | 1.56% |
| 4 | Industrials | XLI | +17.7% | -10.2% | 1.15% |
| 5 | Materials | XLB | +16.2% | -12.0% | 1.68% |
| 6 | Financials | XLF | +7.3% | -14.2% | 1.42% |
| 7 | Real estate | XLRE | +6.5% | -8.7% | 3.12% |
| 8 | Consumer staples | XLP | +4.3% | -9.7% | 2.58% |
| 9 | Consumer discretionary | XLY | +1.3% | -15.1% | 0.78% |
| 10 | Communications | XLC | +0.1% | -11.6% | 1.32% |
| 11 | Utilities | XLU | -0.6% | -10.4% | 2.70% |
Only energy, technology and health care cleared SPY's +18.7%. Industrials and materials came close; the remaining six fell well short. Which means picking a sector is also a decision that lands below the market more often than not. Any discussion of rotation that skips this is half an argument.
🧩 Two places the textbook breaks
Overlay that ranking on the four-phase table and two things stand out.
① Defensives lagging — consistent with theory
Utilities (-0.6%) and staples (+4.3%) sit at the bottom. The classic recession shelters trailing suggests the market is not pricing a downturn. That lines up with the fear-and-greed reading holding around 64 (Greed) in recent briefs.
② Energy and tech together at the top — inconsistent with theory
Here's the problem. By the textbook, energy leads the late phase and technology leads the mid phase. Two sectors from different phases taking first and second isn't explicable within a single-cycle frame.
Two readings are available. One is that structural forces outside the cycle lifted each separately: technology is absorbing AI infrastructure demand that has little to do with the business cycle (see our semiconductor outlook), while energy reflects geopolitical risk stacked on tariff-driven price pressure. The other is that the market sits in late expansion, where the characteristics of two phases genuinely overlap.
This is a stretch where naming the phase confidently isn't possible — and strategies that bet on getting the phase right are exactly the ones that break here. The cycle frame explains well after the fact and forecasts far less well in advance.
🏦 How the rate environment shapes sectors
If one variable separates sector performance, it's rates. The policy rate stands at 3.50–3.75%, and ahead of the September FOMC the discussion has included a hike rather than a cut — the full account is in our July CPI and PPI analysis.
| When rates rise | Effect | Past year, actual |
|---|---|---|
| Utilities | Yield appeal fades against bonds · heavy debt loads | -0.6% (last) — consistent |
| Real estate | Higher funding costs · asset values discounted | +6.5% (7th) — consistent |
| Consumer discretionary | Credit-dependent spending contracts | +1.3% (9th) — consistent |
| Financials | Wider margins (+) vs credit risk (−) | +7.3% (6th) — mixed |
| Energy | Oil prices and supply dominate over rates | +44.4% (1st) — unrelated |
As the table shows, all three rate-sensitive sectors sit in the bottom half. That points to the rate level mattering more than the cycle phase here — the setup flagged in our higher-for-longer scenario, now visible in sector returns. Why financials came out "mixed" — banks and payments/asset managers react to rates in opposite directions inside the sector — is broken out in the financials-by-rate-regime analysis.
⚠️ Three reasons rotation strategies fail
The theory is tidy, which is precisely why it breaks in practice. Generally for three reasons.
① Phase identification is retrospective
Whether you're in expansion or slowdown is only settled afterwards. Even recessions take months to be officially dated. In real time, overlapping signals like ② above are the norm, not the exception.
② The market moves first
Prices discount the economy ahead of the data. By the time indicators confirm a slowdown, rotating into energy and materials is frequently late. For rotation to work you'd have to read the turn before the data does — an entirely different level of difficulty.
③ Frequent switching accrues costs
Moving between sectors stacks up commissions, FX spreads and taxes. For Korean investors in US equities, capital gains tax (22% above the annual ₩2.5M exemption) is triggered on realization, so frequent switching erodes after-tax returns. Our tax guide covers this in detail.
On return alone energy (+44.4%) dominates — but its -14.9% drawdown was the second deepest of the eleven, behind consumer discretionary (-15.1%). Real estate, by contrast, paired a modest +6.5% with the shallowest drawdown at -8.7%. Identical returns can demand completely different tolerance — whether you could actually hold it matters as much as the number.
🛡️ Putting it to use — check, don't predict
Pulling it together: the practical use of rotation theory is less about naming the next phase and more about noticing the concentration you already carry.
□ Have you actually computed your sector weights? — real weights require looking through your ETFs, not just listing individual holdings
□ Does any single sector exceed half the portfolio? Technology in particular repeats across multiple ETFs and usually runs heavier than people think
□ If you're concentrated in the leaders, is that a decision or an accident?
□ When switching sectors, have you priced in tax and fees?
□ Beyond return, can you sit through the drawdown?
The first item carries the most weight. Most investors know their individual position sizes but not their true sector exposure once ETF holdings are added in. Hold QQQ alongside individual tech names and your technology weight is far above what's visible. marketbrief's portfolio diagnosis runs a look-through that adds sector exposure across ETFs, free — worth checking the number before anything else.
Accept that phase calls are hard, and fixing your sector allocation and rebalancing on a schedule becomes the alternative. A mechanical rule that trims what rose and tops up what fell structurally blocks the buy-high-sell-low reflex. For combining this with a contribution schedule see our DCA guide; if sector ETFs are new to you, start with the US ETF primer.
📅 What to watch from here
The variables most likely to reshuffle sector leadership:
| Variable | Sectors affected | Why it matters |
|---|---|---|
| September FOMC | Utilities · Real estate · Financials | A hike would extend the drag on rate-sensitive sectors |
| Inflation prints (PCE, CPI) | Energy · Materials | Persistence is the case for commodity sectors |
| Durability of AI capex | Technology · Industrials · Utilities | Data-centre power demand is an upside factor for utilities |
| Geopolitical risk | Energy · Defence | Oil spikes drive energy sector performance |
One addition to that last row — as the third item suggests, the paths by which one sector's shift spills into another are multiplying. AI data centres consuming power at scale may mean utilities no longer behave as a pure defensive. It's part of why the four-phase frame keeps fitting a little worse each year.
