Market Observations & Portfolio Commentary
Mid Cap – 2Q2026 vs. Russell Midcap
Market Update
U.S. equities staged a reversal in Q2, with the Russell 3000 Index gaining 15.4% and the S&P 500 posting its strongest quarter since 2020. The rally was fueled by AI infrastructure spending and an earnings season that beat expectations, overcoming early-quarter anxiety over the Middle East conflict. Momentum built in late June after the U.S.-Iran peace deal eased oil prices and gave rates room to retreat. Headwinds included a hawkish shift in Fed expectations toward a hike, and a reversal in Energy after a solid start to the year. The quarter reflected optimism around AI and earnings colliding with an uncertain rate outlook.
Equity leadership shifted beneath the headline rally. Technology, the weakest sector to start the year, surged to lead the market as the only sector to outperform the S&P 500, driven by a historic rebound in semiconductors. Energy was the worst performer as oil prices retreated, while defensive sectors, including Utilities and Consumer Staples, also declined. Small caps outpaced large caps despite AI-driven leadership at the top. Momentum and Volatility factors led, Value and Growth were mixed, and Quality and Yield, areas our portfolios tilt toward, were headwinds.
Key Performance Takeaways
-
The London Company Mid Cap portfolio returned 9.7% (9.5% net) during the quarter vs. a 13.8% increase in the Russell Midcap Index. Stock selection was a headwind to relative performance, partially offset by sector allocation.
-
The Mid Cap portfolio produced strong absolute returns in Q2 but fell short of our 85–90% upside capture expectations relative to the Russell Midcap. The market was led by momentum and high-beta factors — in fact, the top beta quintile returned over 44% and drove nearly two-thirds of the index’s gain. Quality was among the weakest factors and our underweight to Information Technology adding to the headwind. Down the cap spectrum, only 25% of profitable Russell 2500 companies outperformed the index in Q2, underscoring how this rally rewarded momentum over fundamentals. Historically, rallies this narrow are hard to sustain.
- Encouragingly, relative performance improved sharply in June as participation began to widen, and we remain confident our diversified exposure to durable, high-quality businesses positions the portfolio to compound attractively over full cycles.
Top 3 Contributors to Relative Performance
-
Entegris, Inc. (ENTG) – ENTG was a top contributor, benefiting from improving semiconductor demand, accelerating AI investment, and rising fab utilization. Beyond the industry recovery, management outlined a clear path to structurally higher earnings through manufacturing optimization, improved working capital, and rebuilding the operating model over time. We remain attracted to ENTG’s strong competitive position, high barriers to entry, and long runway for free cash flow expansion.
-
Bruker Corporation (BRKR) – BRKR outperformed following solid quarterly results and continued margin execution despite maintaining a conservative outlook. The company continues to benefit from strong product innovation, disciplined capital allocation, and a diversified portfolio of leading analytical instruments. We remain confident in BRKR’s long-term growth opportunities.
-
Keysight Technologies Inc. (KEYS) – KEYS advanced after reporting strong quarterly results and better-than-expected guidance, driven by robust demand for AI-related data center testing. We continue to view KEYS as the industry leader in electronic test and measurement, with durable competitive advantages supported by its scale, technology, and customer relationships.
Top 3 Detractors from Relative Performance
-
Domino’s Pizza, Inc. (DPZ) – DPZ declined as domestic and international same-store sales fell short of expectations amid a challenging consumer backdrop. While near-term industry sentiment remains weak, we continue to believe DPZ’s asset-light business model, global scale, and consistent market share gains support attractive long-term earnings growth.
-
Allison Transmission Holdings, Inc. (ALSN) – ALSN declined despite solid quarterly execution, as unchanged guidance and macro uncertainty across several end markets weighed on investor sentiment. It delivered better-than-expected margins in its core transmission business through strong pricing and cost discipline, while integration of the Dana Off-Highway acquisition remains on track. We continue to believe ALSN is well positioned to benefit from recovering end markets, acquisition synergies, and its disciplined approach to capital allocation.
-
Armstrong World Industries, Inc. (AWI) – AWI declined as softer commercial construction activity weighed on near-term results. Despite these headwinds, backlog growth, innovation, and margin expansion initiatives remain intact. We continue to believe AWI’s leading market position supports attractive long-term earnings growth.
Sector Influence
We are bottom-up stock pickers, but sector exposures influenced relative performance as follows:
-
What Helped: Underweight Energy & Utilities (two weaker performing sectors)
-
What Hurt: Underweight Information Technology (a better performing sector) & overweight Materials (a weaker performing sector)
Trades During the Quarter
-
Reduced: Keysight Technologies (KEYS) – Trimmed on strength to manage position size and fund additional opportunities. Our favorable view of KEYS’s leadership in electronic testing & measurement is unchanged.
-
Reduced: Entegris (ENTG) – Trimmed on strength to manage position size and fund additional opportunities. Our long-term constructive view on its positioning within semiconductor materials remains intact.
-
Exited: Lamb Weston (LW) – Sold LW due to its small position size and weaker demand trends across the restaurant and foodservice channel.
-
Exited: Otis (OTIS) – Sold OTIS due to its small position size and to fund higher conviction opportunities.
- Initiated: AppFolio (APPF) – APPF is a leading provider of cloud-based software solutions for the residential property management industry. APPF serves more than 22,000 customers managing roughly 9.5 million units through an integrated platform that combines accounting, leasing, payments, maintenance, and communications tools. APPF primarily serves small-to-midsize property managers within a highly fragmented market, and it has penetrated less than 15% of its estimated addressable market. Despite functioning as a mission-critical operating system for its customers, APPF’s software solutions represent a fraction of the gross rent revenue—creating a meaningful opportunity for continued value-chain monetization over time. High switching costs, deep workflow integration, and an expanding product suite support durable competitive advantages, while the financial profile is attractive: gross margins above 60%, free cash flow margins in the mid-20% range, and returns on invested capital above 20%. We believe the market underappreciates both the durability of APPF’s competitive position and the magnitude of its long-term earnings power.
- Increased: Cooper Companies (COO) – Addition reflects continued confidence in COO’s leading position in contact lenses and improving demand trends across premium product categories. Ongoing operational improvements, a strategic review process, and an attractive valuation relative to long-term growth and free cash flow provide additional upside from here.
- Increased: Somnigroup International (SGI) – Addition reflects our view the current valuation underappreciates SGI’s share gains, synergy execution, & vertical integration progress during a period of well-below-trend replacement-cycle demand. As industry demand normalizes, we see a compelling path to improved earnings power.
- Increased: NewMarket (NEU) – Addition reflects confidence in NEU’s resilient business model, disciplined operating culture, and strong free cash flow generation, which continues to support buybacks and dividends. While petroleum additives demand remains soft near-term, we see additional long-term upside from NEU’s recent aerospace and defense acquisitions.
Looking Ahead
Our outlook remains broadly constructive, supported by a healthy earnings backdrop, resilient economic data, and the prospect of meaningful long-term productivity gains from artificial intelligence. That said, headwinds facing today’s market leadership are accumulating in ways we believe matter. The AI capex boom is real but increasingly fragile, as free cash flow at several hyperscalers has turned negative even as their share prices continue to compound. Geopolitical and tariff conditions remain fluid, and further Fed rate cuts may prove difficult against stubbornly sticky inflation, low unemployment, and resilient economic activity. Layered on top of historic index concentration and valuations requiring near-flawless execution, the cumulative case for discipline is hard to ignore.
From an equity market perspective, broadening at the large-cap index level has masked a narrower reality beneath the surface, with leadership rotating between concentrated energy and AI-related technology bets accompanied by significant speculation. With valuations and earnings expectations elevated and dividend yields near multi-decade lows, we believe it is prudent to expect more modest equity returns ahead. Against this backdrop, our approach, anchored in quality, high active share, and sources of downside protection, can serve as important ballast and a valuable diversifier for portfolios going forward.
