In 2025, the S&P 500’s performance has been increasingly dominated by mega-cap technology stocks benefiting from a historic surge in AI data center capital expenditures (capex). While this AI-driven boom has fueled impressive index-level returns, it also introduces significant concentration risk for investors—especially if the pace of AI-related spending slows or fails to translate into proportional revenue growth. The mismatch between the $350+ billion projected AI infrastructure spend by hyperscalers (Amazon, Microsoft, Google, Meta, Oracle) and the much smaller realized revenues (e.g., OpenAI’s $12 billion annualized run rate) highlights the fragility of current market dynamics.
The KAR Thematic Quality Approach
Preference for Recurring Revenues
KAR targets companies with business models that generate steady, repeatable cash flows—such as software subscriptions, consumables, and membership-based food retailers—reducing reliance on cyclical, one-time sales tied to infrastructure buildouts.
Exposure to Distinct Structural Themes
The portfolio emphasizes enduring trends such as inflation relief, cybersecurity, cloud computing, and the digital economy amongst others. These themes are supported by secular shifts in consumer behavior, enterprise priorities, and technological adoption, offering growth drivers that are less correlated with the AI infrastructure cycle.
Idiosyncratic Growth Opportunities
KAR actively seeks companies with durable competitive advantages—such as network effects, cost leadership, or high switching costs—that are gaining market share within their thematic context. As an all-cap strategy with a concentrated portfolio approach, KAR’s Thematic Quality portfolio seeks to identify and invest in companies with growth opportunities distinct from their own specific businesses. We believe this allows for targeted exposure to unique, high-conviction ideas, further diversifying risk away from broader market exposures.
A Deeper Dive: Investing in Enduring Structural Themes
KAR Thematic Quality defines investment themes as enduring structural shifts—driven by identifiable forcing functions—that reshape industry dynamics in favor of robust business models. By favoring recurring revenue businesses, the strategy seeks to organically position itself to benefit from themes that differ meaningfully from those dominating the broader market. This difference is particularly meaningful today when the S&P 500 is heavily overweight in the AI Data Center Capex theme.
Representative Areas of Overweight Exposure
-  Inflation Relief
Persistent inflationary pressures, driven by government indebtedness and ongoing monetary debasement, are reshaping consumer behavior and business operations. KAR Thematic Quality seeks out companies that deliver value through bulk purchasing, limited assortment, and scale-based savings. In our view, these businesses are positioned to benefit as consumers prioritize stretching their dollars further in an inflationary environment. -  Cyber Security
The frequency and sophistication of cyberattacks continue to escalate, with AI amplifying both the threat landscape and the need for robust defenses. Cybersecurity has become mission-critical for enterprises, transforming from a discretionary IT expense to a core operational necessity. As an example, KAR Thematic Quality participates in this theme through a Cyber Security vendor that is a key infrastructure provider for secure global internet access. This pivotal position has allowed the same Cyber Security vendor to also become a gateway for secure Generative AI Inference workloads. -  Cloud Computing
Cloud adoption is accelerating as businesses seek scalable, efficient, and secure solutions for software deployment and data management. Cloud-native architecture allows for rapid innovation, seamless updates, and operational efficiencies that legacy on-premises systems cannot match. KAR Thematic Quality targets ownership of highly embedded cloud software providers, who have been able to utilize their position within clients’ daily workflows to become the enablers of Generative AI usage within clients’ enterprises. -  Digital Economy
The shift from physical to digital commerce is a defining trend of the modern economy. Digital platforms offer frictionless transactions, infinite shelf space, and real-time availability, capturing market share from traditional retail and service models. KAR Thematic Quality seeks to own digital businesses gaining market share from traditional brick-and-mortar incumbents due to internet-driven efficiencies – often found in nonintuitive industries such as insurance or restaurants. 
Why This Matters for Investors
History shows that early infrastructure booms (e.g., telecom in the 1990s) do not always translate into lasting investment success for the first wave of large companies participating. We believe that the current imbalance between AI capex and monetization could lead to heightened volatility if expectations are reset. By diversifying away from this single macro engine, investors have the potential to reduce portfolio fragility and position themselves for more stable, long-term returns.
The KAR Thematic Quality strategy is designed to strive for balanced equity exposure, capturing opportunities across multiple secular trends while maintaining a disciplined focus on quality and resilience. For investors seeking to mitigate concentration risk and enhance thematic diversification, this approach may offer a compelling alternative to traditional, index-heavy allocations.
