Asset owners hold steady on US markets but push for diversification: Morningstar study

The world's largest institutional investors remain committed to US markets despite mounting policy uncertainty, but they're quietly reshaping their portfolios to manage concentration risk and build resilience, according to new findings from Morningstar.

“Asset owners act as stewards for some of the largest pools of global capital and as fiduciaries for a wide range of beneficiaries and key stakeholders. As a result, they often find themselves on the forefront of shifts in the market environment, global investment strategy, and regulatory standards and policy," said Lindsey Stewart, director of institutional insights at Morningstar in the release. "This year, we’ve seen plenty of changes across all of those factors, so the conversation with this cohort has brought several important issues and pressure points to the surface.”

The investment research firm's latest Asset Owner Perspectives Survey, drawn from interviews with 25 major institutional asset owners across North America, Europe, and Asia-Pacific, reveals a cohort navigating a complex landscape of geopolitical volatility, evolving climate expectations, and cautious experimentation with artificial intelligence.

US exposure remains too big to ignore

The dominance of the Magnificent Seven stocks and broader US market concentration ranked among asset owners' top concerns. Yet the practical reality of managing institutional capital means walking away isn't an option. The opportunity cost of underweighting US equities — particularly for index-oriented managers — remains too significant to justify a wholesale pullback, respondents indicated.

Instead, asset owners are responding by deepening diversification across asset classes. Infrastructure, real estate, and other investments offering inflation-linked or stable cash flows are gaining favour, alongside continued expansion into private credit and private equity. Australian superannuation funds, in particular, emphasized building portfolio resilience as the best answer to a world defined by greater divergence and volatility.

AI is useful, but not trusted with big decisions

Artificial intelligence is gaining traction inside institutional investment operations, but almost exclusively in back-office and productivity applications. According to Morningstar, asset owners reported using AI tools to streamline internal workflows and improve efficiency, yet they remain wary of handing the technology any role in strategic decision-making.

Governance and risk concerns are the primary brakes on broader adoption. Most organizations described a measured, test-and-learn approach rather than aggressive deployment, a posture that reflects lingering doubts about AI's reliability without human oversight.

Climate commitments persist quietly

Sustainable investment hasn't disappeared from institutional agendas, but the conversation around it has grown more nuanced. Notably, political and regulatory pressures, particularly in the US - where several major companies and asset managers have pulled back on public climate commitments - are reshaping how asset owners discuss and pursue environmental objectives.

Still, the underlying demand for better data on climate risk, nature, and biodiversity remains strong. European asset owners in particular noted that the retreat from public targets by some US firms doesn't necessarily signal an abandonment of climate-related action behind the scenes. The gap between public positioning and private practice, they suggested, may be wider than headlines imply.

Asset owners are also calling on data providers to deliver more sophisticated tools for measuring and managing these risks, a signal that climate considerations remain firmly embedded in fiduciary thinking even as the rhetoric shifts.

Morningstar plans to field the quantitative phase of its survey in July and August, with full results expected in September.
