Energy And Materials Lead Sector Declines As Broader Market Advances

Looking at the sectors faring worst as of midday Tuesday, shares of Energy companies are underperforming other sectors, showing a 2.4% loss. Within the sector, APA Corp (APA) and Occidental Petroleum Corp (OXY) are two large stocks that are lagging, showing a loss of 6.2% and 4.9%, respectively. These moves come against a backdrop of recent volatility in crude oil and natural gas benchmarks, as investors reassess the outlook for global demand, OPEC+ production discipline, and geopolitical risk premia that had previously supported energy equities.

Among energy ETFs, one ETF following the sector is the Energy Select Sector SPDR ETF (XLE), which is down 2.6% on the day, and up 25.33% year-to-date. XLE is one of the largest and most liquid sector funds in the U.S. market, tracking the Energy Select Sector Index and providing concentrated exposure to integrated oil & gas companies, exploration and production names, oilfield services providers, and midstream operators. The fund is often used by institutional investors and traders as a proxy for the overall U.S. energy complex, and its intraday performance can reflect shifts in interest-rate expectations, commodity prices, and risk sentiment toward cyclicals.

APA Corp, meanwhile, is up 52.37% year-to-date, and Occidental Petroleum Corp is up 34.89% year-to-date. Both companies are heavily leveraged to upstream oil and gas production, making their share prices particularly sensitive to changes in spot and forward commodity curves, hedging strategies, and capital allocation decisions such as share repurchases and dividend policies. Combined, APA and OXY make up approximately 3.0% of the underlying holdings of XLE, so their weakness is contributing meaningfully to the ETF's underperformance on the day, even as they remain strong performers on a year-to-date basis.

On a valuation basis, many large-cap energy names, including APA and OXY, continue to trade at discounts to the broader market on earnings and cash-flow multiples, in part reflecting investor concerns about the cyclicality of profits, long-term demand uncertainty in the transition to lower-carbon energy sources, and potential changes in regulatory and tax regimes. At the same time, sector balance sheets have generally improved in recent years, and a number of companies have emphasized shareholder returns through higher dividends and variable or special distributions, as well as debt reduction and buyback programs.

The next worst performing sector is the Materials sector, showing a 0.4% loss. Among large Materials stocks, LyondellBasell Industries NV (LYB) and Dow Inc (DOW) are the most notable, showing a loss of 3.9% and 3.4%, respectively. These declines come as investors weigh mixed signals on global manufacturing activity, construction spending, and industrial production, all of which are key demand drivers for chemicals, plastics, coatings, and specialty materials.

One ETF closely tracking Materials stocks is the Materials Select Sector SPDR ETF (XLB), which is down 0.6% in midday trading, and up 14.91% on a year-to-date basis. XLB seeks to track the Materials Select Sector Index and typically holds companies involved in chemicals, construction materials, containers and packaging, metals and mining, and paper and forest products. The ETF is widely followed as a benchmark for U.S. materials exposure and can be used by portfolio managers to express cyclical views tied to economic growth, housing trends, and commodity price cycles in metals and industrial inputs.

LyondellBasell Industries NV, meanwhile, is up 69.16% year-to-date, and Dow Inc is up 67.30% year-to-date. Both companies benefit when input costs such as natural gas liquids and other feedstocks remain contained relative to selling prices for plastics, resins, coatings, and other downstream products. Their strong year-to-date performance reflects improved operating margins, cost discipline, and investor expectations for a continued recovery in end-market demand, even as the stocks give back some gains in today's session. Combined, LYB and DOW make up approximately 5.6% of the underlying holdings of XLB, making their intraday declines a notable headwind for the ETF.

From a sector-allocation standpoint, the divergent performance between Energy and Materials on the one hand, and more defensive or growth-oriented sectors on the other, underscores the importance of diversification at both the equity and ETF level. Investors with heavy exposure to cyclical groups tied to commodities and industrial production may experience higher portfolio volatility, particularly around macro data releases, central bank policy decisions, and commodity price shocks.

Comparing these stocks and ETFs on a trailing twelve month basis, below is a relative stock price performance chart, with each of the symbols shown in a different color as labeled in the legend at the bottom. Relative-performance analysis can help investors separate short-term noise from longer-term trends, and may highlight which areas of the market have led or lagged as monetary policy, inflation expectations, and commodity prices have evolved over the past year.

For investors considering adjustments to sector positioning, it can be useful to pair price performance with fundamentals such as earnings revisions, free-cash-flow yields, and balance-sheet leverage, as well as with macro indicators like purchasing managers' indexes, inventory levels, and housing starts. Short-term pullbacks in sectors such as Energy and Materials can represent either opportunities or value traps, depending on whether profits prove resilient in the face of changing economic conditions.

Here's a snapshot of how the S&P 500 components within the various sectors are faring in afternoon trading on Tuesday. As you can see, six sectors are up on the day, while three sectors are down.

Sector	% Change
Services	+1.0%
Healthcare	+0.9%
Industrial	+0.7%
Financial	+0.6%
Technology & Communications	+0.5%
Consumer Products	+0.3%
Utilities	-0.2%
Materials	-0.4%
Energy	-2.4%

The sector table shows that, despite notable weakness in commodity-linked areas, the broader equity market is supported by gains in Services, Healthcare, Industrials, Financials, Technology & Communications, and Consumer Products. This pattern is consistent with a market that is rotating within risk assets rather than exiting them altogether, and highlights the role of sector-level dispersion in driving relative performance for active managers and strategic asset allocators.
