Market update: Thursday, July 9, 2026
Construction-related equities delivered a split performance this week, with the divide falling squarely along business-model lines.
Aggregates and building-materials producers have been sliding on deal-related jitters and margin worries, while electrical, mechanical, and grid-infrastructure contractors continue to hold up thanks to the ongoing AI data center and power-grid buildout.
Here’s what’s driving the sector today and what it means for investors watching construction stocks.
Broader Market Backdrop
Wall Street closed lower on Wednesday, July 9, with the Dow Jones Industrial Average dropping over 1% to settle near 52,348, weighed down by declines in 24 of its 30 components.
The S&P 500 slipped modestly, while the Nasdaq Composite managed a small gain on strength in AI-related names.
Within the S&P 500’s sector breakdown, the Industrials Select Sector SPDR fund fell sharply, reflecting the pressure on industrial and construction-adjacent names, even as defensive sectors like healthcare, energy, and real estate advanced.
Rising oil prices and geopolitical tension in the Middle East added to the cautious mood, pushing input costs higher for materials-heavy businesses.
Materials Companies Under Pressure
The building-materials corner of the construction sector has been the clear laggard in recent sessions:
Martin Marietta Materials (NYSE: MLM) has been one of the sector’s biggest decliners.
Shares fell roughly 4% on July 8 alone, closing near $570, and are now down more than 8% year-to-date. The slide follows the company’s announcement of a $13.5 billion acquisition of Lhoist North America — its largest deal in years.
Because the transaction is being funded with a heavy equity component (roughly $6.5 billion in stock alongside $7 billion in cash), investors are pricing in near-term dilution risk and a jump in leverage, with net debt expected to climb to roughly 3.7 times EBITDA at closing.
A cautious “Hold” initiation from Berenberg added to the selling pressure.
Vulcan Materials (NYSE: VMC), Martin Marietta’s closest peer in the aggregates business, has also cooled off after a strong run, in what analysts describe as a classic “sell the news” pullback rather than a reaction to fresh negative developments. Both aggregates giants were recently downgraded by BofA Securities after outsized rallies left valuations stretched.
Carlisle Companies (NYSE: CSL), a major roofing and building-products manufacturer, has also traded lower, dropping roughly 4% on renewed cost-inflation concerns.
Truist Securities cut its price target on the stock, citing rising petrochemical prices and supply disruptions affecting MDI, a key raw material for commercial roofing products, that are expected to squeeze margins through the rest of 2026.
Elsewhere in materials, UFP Industries remains down more than 11% year-to-date, and Sherwin-Williams has also traded lower alongside its building-products peers, reflecting broader softness tied to housing-market sensitivity, input-cost inflation, and energy-price volatility.
Infrastructure and Specialty Contractors Hold Firm
While materials producers wobble, the infrastructure and specialty-contracting side of the construction sector tells a very different story — one still powered by the AI data center boom, grid modernization, and electrification spending.
Quanta Services (NYSE: PWR), the largest U.S. electric-transmission contractor, has climbed roughly 69% year-to-date, supported by a record backlog exceeding $39 billion. Its first-quarter 2026 earnings per share jumped 51% year-over-year on 26% revenue growth.
MasTec (NYSE: MTZ) has outpaced even Quanta, gaining nearly 97% so far in 2026, driven by accelerating demand across its communications, clean energy, and pipeline infrastructure segments. Full-year 2026 EPS estimates have been revised upward to $8.90 from $8.60 in just the past two months.
Comfort Systems USA (NYSE: FIX), a mechanical and electrical installation specialist increasingly tied to data-center cooling projects, has more than doubled in 2026, up roughly 109% year-to-date — the standout performer among large-cap construction names.
EMCOR Group (NYSE: EME) rounds out the group with a 33% year-to-date gain, backed by record quarterly revenue, record EPS, and a backlog of $15.6 billion, up nearly 33% from a year earlier — much of it tied to high-margin data-center electrical and cooling work.
Collectively, these infrastructure-focused names have dramatically outperformed both the broader Zacks Construction sector (up about 18% in 2026) and the S&P 500 (up roughly 7%), underscoring how unevenly capital is flowing within the construction universe.
Why the Sector Is Splitting
The divergence comes down to end-market exposure:
- Materials and residential-linked names (aggregates, roofing, lumber, building products) are more sensitive to mortgage rates, housing starts, and raw-material costs like diesel and petrochemicals — all of which have become headwinds amid elevated energy prices and a 30-year mortgage rate hovering near 6.4%.
- Infrastructure and specialty contractors are riding a multiyear capital-spending wave tied to AI data centers, grid modernization, broadband expansion, and utility electrification — demand that is largely insulated from housing-market cycles and backed by record contract backlogs.
Analysts at Jefferies have pointed to this same split, noting that construction-materials stocks less exposed to consumer spending and energy costs — including Martin Marietta, Vulcan Materials, and Ferguson — still look attractively valued after recent pullbacks, even as near-term margin pressure from higher diesel costs persists.
What Investors Are Watching Next
- M&A integration risk: How Martin Marietta manages the Lhoist North America deal’s financing and debt load will be a key swing factor for materials stocks.
- Interest rates and housing data: Any signal on Federal Reserve rate policy or a rebound in single-family housing starts could reverse sentiment on residential-linked materials names.
- Data center capex trends: Continued hyperscaler and utility investment will remain the primary driver for infrastructure contractors like Quanta, MasTec, EMCOR, and Comfort Systems.
- Input costs: Diesel, petrochemical, and other raw-material prices will continue to pressure margins across both segments, though infrastructure firms have shown greater pricing power so far in 2026.
Bottom Line
Construction stocks aren’t moving as one homogenous group right now — they’re splitting into two distinct stories.
Materials and residential-exposed companies are digesting deal risk, cost inflation, and housing-market uncertainty, while infrastructure and specialty contractors tied to AI, data centers, and grid modernization continue to post record backlogs and market-beating returns.
For investors, the sector underscores the importance of looking past the “construction” label and evaluating each company’s specific end-market exposure.
