Investors are searching for diversifiers as the AI market becomes more crowded. Several options are hidden in plain sight.

The massive spending on AI in the last year has boosted earnings for corporations. Companies associated with this splurge, as represented by an iShares?ETF, have seen their?stocks double from?June of 2025 to this June before a recent drop. BlackRock reports that the "momentum factor" - which is where winning stocks continue to?win - has outperformed all other factors over the last five years. It gained nearly 200%. Diversification is not a strategy that has been rewarding. This could change. Goldman Sachs says that the AI market is the most crowded ever. This has led many investors to wonder which parts of the market could offer an alternative if this AI boom fails.

Three options are available.

First, healthcare. The current global equity index strategy is not as diverse as you would expect. According to our analysis of global stock returns over the last 12 months, the MSCI All Country World Index has a correlation with AI stocks of 0.79 and with the momentum factor of 0.76, which means that the?returns are closely related.

Healthcare stocks had a negative correlation with AI of 0.06 and a momentum factor of 0.12. There was, in other words almost no correlation between the movement of AI stocks and that of healthcare stocks over the last year.

It is clear that healthcare has been a good diversifier. We expect healthcare to continue to play a role in protecting portfolios from downturns, due to its long history of strong earnings growth. Long-term changes such as the demographic shift and innovation in medical technology, as well as pharmaceuticals, continue to boost profits.

In the past 30 years, the strength of healthcare earnings has translated into higher valuations for healthcare compared to the market. AI's dominance over the last few years has led to healthcare trading at a discount of 15%.

We believe that while healthcare offers attractive valuations and strong earnings, it is important to be selective. According to?FactSet & BlackRock, the healthcare sector had more stock-specific volatility than any other sector last year.

We prefer companies that embrace technology change. Combining large?medical data with AI models could, for example speed up the detection and treatment. This will not change, even if AI as a whole fades.

OLD ECONOMY, NEW CASE

Latin America is the second. Investors have mostly overlooked equity markets in Latin America, which have had a low relationship with AI and momentum over the past few years. According to BlackRock, Latin America accounts for just 0.8% in the MSCI ACWI but 7% in global GDP. This gap could close in the next few years, according to BlackRock.

Brazilian and Mexican shares are also trading below their historical values, while most major markets are at a premium. Interest rate cuts in the near future, which would benefit their domestic economies, as well as, on a longer-term basis, rising commodity demand due to?AI and electricification, could be catalysts for a rating reassessment.

The UK, my home market, has a low correlation with AI of 0.26 and has proven resilient to market turmoil over the past few years, fueled by the COVID-19 Pandemic, geopolitical conflict, and inflationary spikes.

Over the last five years, the FTSE 100 outperformed the global stock market on a total returns basis - without having much or any exposure to pure AI.

The UK market is characterized by its exposure to sectors of the "old economy", which are less susceptible to disruption from AI, including financials, materials and energy. As with healthcare, there are many reasons to believe that these sectors will benefit from AI. This could be through cost-cutting in banks or increased demand for copper due to AI and electrification. After a decade of six different prime ministers, political stability could be a catalyst to help UK stocks close the gap in valuation with developed markets. Stability could lead to greater economic confidence, which would encourage domestic investors to buy UK stocks in addition to foreign investors.

This diversification strategy carries a risk: AI could continue to grow while diversifiers, which are meant to protect portfolios, drag down performance. Although there are many reasons to be optimistic about the three above areas over the long-term, there are not many catalysts that will lead to AI outperforming them in the near term.

The AI trade could stall, either due to fears of over-investment or an unforeseen event. We've seen a drop in the U.S. Semiconductor Index just this month. Holding stocks to help weather the storm seems sensible.
