Stock market sector rotation: Energy leads while communication services suffers a sharp decline
U.S. stock market leadership is becoming increasingly selective. Three trading sessions reveal important differences between sectors, and even between industries within the same sector.
U.S. stocks are showing a notable change in leadership. Between the October 20 and October 23, 2026 closes, the Energy Select Sector SPDR Fund (XLE) gained 2.00%, while the Communication Services Select Sector SPDR Fund (XLC) fell 4.25%. The SPDR S&P 500 ETF (SPY) declined 1.18% over the same period.
For stock investors and traders, the message is not simply that the market is falling. Some sectors are attracting buying interest while others are struggling, and these differences may help identify where the next opportunities and risks develop.
What the latest sector performance tells us
Energy was the strongest of the 11 major U.S. stock market sectors over the three sessions, followed by utilities, which gained 1.62%.
Consumer staples, real estate, financials and materials also finished higher. Together, these six sectors outperformed a declining S&P 500 benchmark.
The weakest performances came from communication services, consumer discretionary stocks, industrials and technology.
The particularly interesting development is the gap between the leaders and laggards. Energy outperformed communication services by 6.25 percentage points in just three sessions.
That is a substantial short-term divergence, although three trading days alone are insufficient to establish a durable rotation.
Why communication services is worth watching
Communication services was not merely the worst-performing sector over this period. Its sector ETF, XLC, declined in all three sessions:
-
Wednesday, October 21: -1.11%
-
Thursday, October 22: -1.42%
-
Friday, October 23: -1.78%
The selling was persistent, with the daily declines becoming larger.
One important contributor was Meta Platforms. After the company disclosed plans for additional financing alongside substantial AI investment commitments, investors became increasingly concerned about how much capital the next phase of AI development would require.
Reuters reported substantial selling in Meta and several other AI-related companies as investors reconsidered financing costs and the potential returns from enormous infrastructure investments.
There was also pressure on telecommunications companies amid reporting about potential new competition in wireless services.
However, communication services includes very different businesses, from digital advertising platforms to traditional telecom providers and entertainment companies. Weak sector performance does not mean every constituent faces the same problem.
What to watch:Whether XLC continues underperforming SPY after the initial selling pressure fades. A sustained recovery in relative performance would weaken the current bearish interpretation. Continued underperformance, even on days when the broader market advances, would be more concerning.
Energy is leading, but is it too late to chase?
Energy’s 2.00% three-session gain was supported by a particularly strong Friday, when XLE advanced 2.60%.
Oil prices rose sharply amid renewed concerns about disruptions to Middle Eastern supplies. Brent crude reached approximately $116.72 per barrel on October 23, according to Reuters reporting.
Higher oil prices can support the earnings outlook for some energy producers. But the relationship is not equally favorable for all energy companies, particularly those facing higher operating costs or differing refining economics.
There is another reason to be selective.
Although the broader energy ETF has shown strong performance, the supplied market research indicates that buying interest has not been equally distributed across energy-related investments. Some exploration-focused products experienced withdrawals even as XLE attracted fresh ETF creations.
That creates an important distinction between a strong sector and an attractive new entry price.
For traders, a pullback that holds support and attracts renewed buying may offer more useful confirmation than purchasing immediately after a sharp advance.
For longer-term investors, sustained commodity prices, company cash flows, valuations and balance-sheet quality matter more than a three-day ETF performance ranking.
The surprising split within technology: Semiconductors versus software
Technology offers perhaps the most useful lesson from this market rotation.
While the Technology Select Sector SPDR Fund (XLK) declined 1.19% over the three sessions, its underlying industries performed very differently.
The VanEck Semiconductor ETF (SMH) fell approximately 3.51%, while the iShares Expanded Tech-Software Sector ETF (IGV) gained approximately 3.42%.
That is a difference of nearly seven percentage points.
This matters because headlines about technology selling can obscure substantial changes in leadership within the sector.
Investors appear to be distinguishing more carefully between businesses exposed to expensive AI infrastructure investment and other technology companies with different revenue, margin and capital requirements.
It would be premature to interpret this as an abandonment of AI. Friday’s stabilization in several semiconductor shares also suggests that buying interest has not disappeared entirely.
A more useful question is whether software continues outperforming semiconductors over subsequent sessions, or whether chip stocks regain their earlier leadership.
For stock selection, that distinction could prove more actionable than simply deciding whether technology is bullish or bearish.
Defensive sectors are holding up, but leadership is not necessarily stable
Utilities rose 1.62% across the three sessions, while consumer staples gained 0.58%.
Both sectors are often considered defensive because electricity, food and household products generally remain necessary even when the economy slows.
However, their performance was not consistently positive throughout the period.
Consumer staples rallied 3.31% on Thursday, then declined 1.92% on Friday. Utilities also retreated on Friday.
In addition, Treasury yields remained elevated, with the U.S. 10-year yield approaching 5%. Higher yields can compete with dividend-paying equities and make financing more expensive for rate-sensitive businesses, including utilities and real estate.
This creates a more nuanced picture than a straightforward flight into defensive stocks.
Relative strength is not the same as absolute strength.A sector can outperform a falling S&P 500 and still lose money, while a sector that recently outperformed may become vulnerable if investors have already crowded into the trade.
Three scenarios investors and traders can monitor next week
1. The rotation continues
Energy maintains relative strength, communication services continues to underperform, and leadership remains concentrated outside previous market favorites.
That would support continued attention to selective energy exposure and caution toward weaker communication-services stocks. The quality of the entry still matters, particularly following large short-term moves.
2. Technology leadership broadens again
Semiconductors recover, technology begins consistently outperforming SPY, and communication services stabilizes.
That would suggest the recent weakness may have been a temporary reassessment of valuations and investment spending rather than the beginning of a more lasting shift.
3. Weakness spreads to more sectors
Consumer discretionary and industrials remain under pressure, while the recent defensive winners also begin to weaken.
In that scenario, investors may become less concerned about which sector is leading and more concerned about whether overall equity market conditions are deteriorating. Market breadth, the number of stocks rising versus falling, would be particularly useful to follow.
The investor takeaway: Follow the rotation, but look beneath the surface
One of the most useful aspects of sector analysis is that it can reveal differences the headline S&P 500 performance does not show.
Over these three sessions, the benchmark declined 1.18%, but the experience of an energy investor was very different from that of an investor concentrated in communication services.
The same applies within technology, where software and semiconductors moved in opposite directions.
This does not automatically make the strongest sector a buy or the weakest sector a short. The stronger opportunity may be found by examining whether leadership is broadening, whether pullbacks attract buyers and whether weaker sectors can recover relative to the market.
The next several sessions, particularly alongside major technology earnings and the Federal Reserve’s October 27-28 meeting, should provide further evidence about whether this is a temporary rotation or the beginning of a more sustained change in stock market leadership.
For now, the central question is worth keeping on the watchlist: Are investors simply rotating within the market, or is weakness in former leaders beginning to spread?
What I find interesting: Record ETF inflows, but investors are becoming more selective
What I find interesting about the latest sector rotation is how it contrasts with the bigger picture of money flowing into exchange-traded funds (ETFs).
According to ETFGI’s finalized September 2026 figures, U.S.-listed ETFs attracted $152.93 billion during September, bringing year-to-date inflows to a record $1.56 trillion. Europe attracted another $51.04 billion during September, taking its year-to-date total to a record $432.45 billion.
Both regions had already exceeded their previous full-year inflow records with three months of 2026 remaining.
Yet something else happened: total ETF assets declined slightly in both regions during September, despite all that new money coming in.
U.S. ETF assets decreased from $16.36 trillion at the end of August to $16.24 trillion in September. European ETF assets slipped from $3.97 trillion to $3.94 trillion.
That illustrates an important distinction for investors. Money can continue flowing into investment products while the market value of their holdings falls. New investments and investment returns are two different things.
Where is the money going?
The composition of September’s inflows also provides an interesting clue about changing investor preferences.
In the United States:
-
Equity ETFs: $41.02 billion in September inflows.
-
Fixed-income ETFs: $40.08 billion, almost matching equities.
-
Commodity ETFs: $3.74 billion.
-
Actively managed ETFs: $61.16 billion, representing a particularly strong area of demand.
Active ETFs are an investment-management category that can include equities and bonds, so these figures should not be added together.
Europe showed a similar appetite for diversification, attracting $26.30 billion into equity ETFs and $9.41 billion into fixed income.
Another notable development is that both regions attracted fewer total ETF inflows in September than in August, despite their record-breaking annual performance.
Does that mean investors are becoming more cautious? Possibly, but flows alone cannot establish their intentions.
The nearly equal U.S. equity and fixed-income inflows are nevertheless worth watching. Investors can continue participating in stocks while simultaneously increasing exposure to bonds, potentially balancing growth opportunities with income and diversification.
What does this tell us about the latest stock sector rotation?
The October sector-performance figures show energy substantially outperforming communication services, while technology itself is dividing between stronger software stocks and weaker semiconductors.
The September ETF data offers a broader perspective: strong overall investment demand does not mean that every sector, asset class or individual stock will attract equal interest.
Even within September’s ETF flows, concentration was striking. Just 20 U.S. ETFs attracted a combined $81.34 billion, with SPY alone accounting for $10.70 billion.
And in Europe, an inverse leveraged oil product attracted $6.10 billion. This product is designed to benefit from falling oil futures prices, illustrating how some ETF-related investments express tactical bearish positions rather than conventional long-term ownership.
Importantly, September’s regional flows cannot explain or confirm the specific sector movements of October 21-23. They cover different periods and different groups of investments. But they do provide context for why examining where money is flowing can be as useful as examining how much is flowing.
A lesson worth remembering
ETF flows tell us where net new money is entering or leaving investment products. They do not prove why investors acted, guarantee future returns or necessarily identify which stocks will outperform next.
For traders, watching sector performance alongside more recent, sector-specific ETF flows could help determine whether a developing rotation is gaining support or losing momentum.
For longer-term investors, the record-breaking annual inflows suggest continued demand for ETFs as investment vehicles. But the performance, valuation and risk of the assets inside those funds remain crucial.
What I find most interesting is that money can be pouring into ETFs at record levels while leadership underneath the stock market is changing dramatically. The opportunity is not necessarily to follow the biggest inflow or buy yesterday’s strongest sector, but to recognize where durable leadership may be developing, and where it may be fading.

Stock Chart of the Week: Lennar breaks higher, but $85 is the next big test
What I find particularly interesting about the latest stock market rotation is that opportunities may be emerging even within sectors that have recently underperformed.
Lennar Corporation (NYSE: LEN) provides a good example.
While the broader consumer discretionary sector has struggled, Lennar, one of America’s largest homebuilders, has staged a significant recovery following a difficult period after its September earnings.
On Thursday, October 22, LEN surged 8.69%, breaking above the declining price channel that had contained its shares since August. Friday’s close at $84.92 preserved the breakout, bringing the two-session advance to approximately 9.3%.
The move becomes even more interesting when compared with the broader sector.
Lennar is outperforming its sector by almost 10 percentage points
Between the October 21 and October 23 closes:
-
Lennar (LEN): +9.29%
-
Equal-weight consumer discretionary ETF (RSPD): -0.57%
-
LEN outperformance: +9.86 percentage points
This is noteworthy because Lennar advanced sharply while the broader consumer discretionary benchmark declined.
The stock has also recovered approximately 18.3% from its October 14 intraday low of $71.78.
That does not prove a lasting bullish reversal, but it does suggest that Lennar’s recent price behavior is becoming more constructive.
Sometimes the most interesting candidates are not found in the strongest sectors. They are stocks beginning to show strength while their broader sector remains under pressure.
Why $85 could be important for Lennar shares
The accompanying daily chart shows that LEN has broken above its declining channel and returned to a previously important trading area.
Around $85 lies the approximate point of control from its earlier earnings-period trading range. This represents the price at which the greatest trading volume occurred during that historical period.
Such areas can attract renewed attention from buyers and sellers because considerable trading previously took place there. However, they do not guarantee that prices will move toward or away from them.
LEN reached $85.21 during Friday’s session before closing at $84.92, just below that reference.
Three areas deserve attention:
Around $85: The immediate test
A daily close above $85, followed by sustained trading or a successful retest, would strengthen the case that buyers are regaining control. Repeated failures around this level could indicate that overhead selling pressure remains significant.
Around $81-$82: The first important support area
If the stock pulls back, this area could help determine whether the recent breakout is sustainable. A successful recovery from this zone would support the bullish interpretation. Sustained trading below it would weaken the recovery case.
Around $90: The next potential upside reference
If buyers establish acceptance above $85, the previous trading area’s upper boundary near $90 becomes a relevant reference. It is not a guaranteed target, and the stock would still need to overcome selling pressure along the way.
A more substantial retreat toward $77-$78 would suggest that much of the recent improvement has been lost.
Does Lennar’s business outlook support a recovery?
This is where investors need to distinguish between improving share-price behavior and improving company fundamentals.
Lennar’s September 16 earnings report showed that its third-quarter new home orders declined 9% year over year, while deliveries fell 3%. The company reported a 15.8% gross margin on home sales and diluted earnings of $1.19 per share.
Those figures illustrate why the investment case is not straightforward.
Mortgage rates, housing affordability and builder incentives remain important influences on demand and profitability.
A decline in mortgage rates could make new homes more affordable and potentially support demand. But investors should also examine whether Lennar can maintain margins without relying excessively on discounts and financing incentives.
The next useful fundamental questions are whether new orders begin recovering, gross margins stabilize and management demonstrates improving profitability.
A technically convincing breakout would become more persuasive as a longer-term investment thesis if those business fundamentals also improved.
What would change the bullish interpretation?
There is a credible opposing argument: Lennar may simply be experiencing a powerful rebound within a previously damaged trend.
The stock remains below earlier trading levels, and two strong sessions cannot establish a durable multi-month recovery.
A failure to hold above the recently reclaimed trading area, especially if accompanied by renewed weakness across homebuilders, would challenge the emerging bullish case.
Conversely, continued relative strength, sustained trading above $85 and improving housing-market fundamentals would provide stronger reasons to investigate the stock further.
The lesson from Lennar and sector rotation
What I find especially interesting is not merely that LEN has rallied almost 9.3% in two trading sessions.
It is that the stock has started behaving differently from its broader sector, breaking a declining technical pattern and recovering important historical trading prices while consumer discretionary shares remain under pressure.
This is precisely why sector analysis should be a starting point rather than the final word when selecting stocks.
A weak sector can contain emerging leaders, just as a strong sector can contain vulnerable companies.
Lennar has achieved an encouraging first step by breaking out of its declining channel. The next test is whether buyers can establish and maintain control around $85. That distinction could help determine whether the recovery deserves increasing attention or remains another temporary rebound.
For now, LEN is a stock worth investigating further, not an automatic buy, at your discretion. I will also note that subscribers to the investingLive Telegram Premium channel received this buy consideration 10 days ago, with a buy entry that filled at $72.10 so those that bought are already up 17.7% in 10 days.
