Morgan Stanley’s Schuyler Hooper argues that investors should focus less on countries and sectors and more on the structural forces driving capital flows

For decades, portfolio construction has followed a familiar playbook. Diversify across regions, sectors and asset classes, combine equities with bonds and rely on historical correlations to manage risk. According to Schuyler Hooper of Morgan Stanley Investment Management, that framework is becoming increasingly challenged by a world undergoing profound structural change.

“It’s really the confluence of deglobalization, reindustrialization and technological change, all accelerating at the same time,” he says. 

While none of these forces are new, Hooper argues that investors continue to underestimate the pace at which they are unfolding. Markets tend to adapt well to gradual change, but struggle when shifts become exponential.

“Humans aren’t very good at thinking about exponential changes,” he notes. “Markets tend to like linear, slow-moving trends because they’re much easier to price.” 

The result is an investment landscape in which traditional allocation frameworks may be less effective at identifying where future returns will come from.

Structural themes are replacing traditional investment buckets

According to Hooper, one of the biggest challenges for investors is that many of the forces driving returns today no longer fit neatly into country, sector or style classifications.

“These themes are driving markets much more than anything idiosyncratic on the single-stock side,” he argues. 

Take electrification. Investors seeking exposure to the theme may find opportunities across utilities, industrials, materials, infrastructure and commodities. Those companies may be listed in different countries and belong to different sectors, yet they are all tied to the same underlying driver. 

This is why Morgan Stanley increasingly favours a thematic framework that starts with structural change rather than traditional market classifications.

“Structural change puts money in motion. We ultimately want to lead the money,” Hooper says. 

The objective is not simply to identify attractive companies, but to understand where capital is likely to flow as governments, businesses and consumers adapt to a changing world.

AI is moving into a new phase

Artificial intelligence offers perhaps the clearest example of how investment themes evolve.

The first wave of AI investing centred on semiconductors, data centres and power infrastructure. More recently, investor attention has shifted towards agentic AI and the technologies needed to deploy autonomous systems at scale, including networking, governance and monitoring solutions. 

But Hooper believes the largest opportunities may still lie ahead. “People are waiting to see the best applications of AI,” he says.

Over the next decade, he expects physical AI to become a major investment theme. Autonomous vehicles, humanoid robots, drones and other intelligent machines could ultimately generate as much disruption as AI is already creating within the knowledge economy. 

The challenge for investors is that leadership within a theme does not remain static. Exposure that worked during the infrastructure phase of AI may not be the exposure that benefits most from the next stage of adoption.

Rethinking diversification

The implications extend beyond equities.

Hooper believes many investors remain anchored to a market regime defined by four decades of falling interest rates and generally favourable stock-bond correlations.

“I think the biggest mistake is assuming that the correlation profile of assets over the past 40 years will guide the next five to ten years,” he says. 

In a world characterised by reindustrialisation, supply-chain restructuring and potentially higher inflation, bonds may no longer provide the same diversification benefits investors have historically relied upon. 

That does not mean abandoning fixed income. Hooper still sees an important role for bonds as a source of income. However, he believes investors may need to broaden their diversification toolkit through real assets, alternative strategies or other sources of uncorrelated returns. 

Nor is he advocating the end of balanced portfolios.

“Diversification is still very important,” he says. “You just need to measure it correctly.” 

Conclusion

Hooper is not arguing that traditional asset allocation is obsolete. He is arguing that the assumptions underpinning it deserve closer scrutiny.

For much of the past four decades, investors could rely on stable relationships between countries, sectors and asset classes. Today, deglobalisation, reindustrialisation and artificial intelligence are creating a market environment where structural themes increasingly cut across those boundaries. 

The challenge for investors is therefore no longer simply deciding how much to allocate to equities, bonds or regions. It is identifying the forces that are reshaping capital flows, earnings growth and economic activity.

In Hooper’s view, the winners of the next decade may not be those with the most precise country or sector calls, but those who best understand how structural change is putting money in motion. And that may require a fundamentally different way of thinking about portfolio construction.
