Artificial intelligence is forcing investors to rethink some of their most deeply held assumptions about the modern economy.

For years, markets rewarded companies built around software, data and digital platforms. But as AI accelerates the pace of technological disruption, attention is increasingly shifting toward businesses that appear less vulnerable to it.

That shift has given rise to what some strategists describe as the “Halo trade” - an investment preference for companies with heavy assets and low obsolescence risk. Few markets embody this idea more clearly than Japan.

 

The rise of the Halo Trade

The Halo trade focuses on companies whose competitive advantage lies in specialised physical assets and industrial expertise that competitors struggle to replicate. Many operate in niche manufacturing or materials sectors where proprietary equipment and decades of engineering knowledge create formidable barriers to entry.

These businesses are rarely the fastest-growing companies in the market. Instead, their appeal lays in resilience - industries where demand evolves slowly and where technological disruption is less likely to erode their competitive position.

In an era where software companies can be upended by new technologies almost overnight, that resilience has become increasingly attractive to investors navigating the uncertainties of the AI revolution.

 

Why Japan stands out

Japan’s corporate landscape is unusually rich in this type of company. The country spent decades maintaining a broad industrial base, even as many Western economies moved away from manufacturing and heavy industry.

For years, this strategy was widely criticised.

After Japan’s economic bubble collapsed in the early 1990s, banks often supported struggling industrial companies through extended lending. Critics argued that this prolonged the life of inefficient firms and slowed economic restructuring.

But the persistence of Japan’s industrial ecosystem has had an unexpected consequence.

It preserved a vast network of specialised manufacturers, engineers and materials producers - many of which now occupy critical positions in global supply chains.

In other words, the very characteristics that once made Japan’s economy appear outdated may now make it unusually resilient.

 

Industrial depth as a strategic advantage

One distinctive feature of Japanese corporations is the breadth of their industrial capabilities. Many companies operate across multiple sectors rather than focusing on a single narrow business line.

While this diversification was often seen as inefficient by investors accustomed to pure-play companies, it has helped preserve technical expertise across a wide range of industries.

That depth is increasingly valuable in a world where geopolitical tensions and technological change are reshaping supply chains.

Governments and corporations alike are now attempting to rebuild industrial capacity - particularly in areas such as semiconductors, energy infrastructure and advanced manufacturing.

In many cases, Japan already has the expertise.

 

The semiconductor materials edge

The semiconductor industry offers a clear example of this advantage.

While companies in the US and Taiwan dominate chip design and fabrication, Japanese firms remain essential suppliers of specialised materials and manufacturing components used throughout the production process.

These niche products - often highly technical and difficult to replicate - can represent bottlenecks in the global supply chain.

As demand for AI chips accelerates, the markets for such materials are expanding rapidly. In some cases, products that once served relatively small markets are becoming critical to industries worth billions of dollars.

Companies producing these specialised inputs therefore occupy a powerful position: they are not necessarily the most visible players in the semiconductor industry, but they are often among the most indispensable.

 

Opportunity with caution

The renewed enthusiasm for industrial resilience does not eliminate risk. The Halo trade, like any investment theme, could fade if market conditions change or if new technologies alter the economics of manufacturing.

Still, the shift in investor thinking highlights an important development.

For years, global markets favoured asset-light companies built around software, data and digital platforms. Today, the rapid expansion of AI infrastructure is reminding investors that the physical foundations of the economy - factories, machinery and specialised materials - remain essential.

In that world, Japan’s industrial landscape may be uniquely well-positioned.
