Artemis: Four of the biggest questions for investors in US equities

Key takeaways

  • Returns in the US market are broadening out beyond the Magnificent Seven
  • The race to increase AI capacity has created numerous bottlenecks in small-and mid-cap stocks across the data centre supply chain
  • Opportunities are also emerging in economically sensitive sectors such as trucking and industrials

Have the Magnificent Seven attracted too much attention? Should investors be looking elsewhere?

Although the Magnificent Seven have driven the US market in recent years, returns are broadening out and we believe significant alpha can be generated outside of these stocks. Heavy investment in AI by large technology companies is creating attractive opportunities for a range of small and mid-cap companies in the US.  

These include software companies. While certain software businesses may be at risk of being replaced by cheaper AI tools, others can benefit from growing adoption of AI.  

Do companies further down the AI supply chain offer better prospects than the hyperscalers? 

Semiconductors are widely recognised as a key bottleneck in the race to increase AI capacity – but we also see opportunities among the companies that equip and build the data centres.   

Despite an AI-related sell-off in July, these stocks have performed very well. And although the valuation multiples of these companies have risen, we expect demand for their products and services to continue to grow – and margins to increase – in response to capital expenditure by hyperscalers. That being said, we manage our portfolios’ exposure to the AI theme dynamically. We are still bullish on AI beneficiaries as a theme but are highly selective, investing only where we see an attractive ratio between risk and reward. 

What are some of the most compelling opportunities in the US market currently? 

A recent ruling by the US Supreme Court is likely to raise costs and tighten capacity in the US trucking industry. That could make other forms of transporting goods, including ‘intermodal transport’ – incorporating different modes of transportation such as rail alongside trucks – increasingly attractive. We invest in J.B. Hunt, a leading provider of intermodal transport, and believe it is well positioned to benefit from this structural shift. 

We are also positive on many industrials, particularly those that reflect idiosyncratic growth stories, such as ATI, a manufacturer of specialty nickel and titanium alloys for aerospace engines and airframes. Demand for new aircraft is strong but supplies remain constrained. So airlines need to invest more in maintaining older engines installed across existing fleets. That is giving ATI pricing power and underpinning attractive earnings growth.  

Away from economically sensitive areas, we are slowly rebuilding our exposure to healthcare across our funds. This sector is just emerging from a long downturn. Overstocking post-Covid resulted in a lengthy fallow period for healthcare stocks but the structural overhangs in numerous end markets have finally started to dissipate. 

Has economic uncertainty had an impact on how you select stocks? 

Our bottom-up process focuses on companies with idiosyncratic growth drivers and asymmetric risk/reward. Although certain sectors are more exposed to economic uncertainty, we are finding plenty of attractive opportunities. We look for companies whose earnings are supported by expanding margins, sustainable free cashflows, strong returns on investment and growing demand. Quest Diagnostics, which carries out diagnostic testing, is a good example. As hospital labs increase outsourcing, strong core testing demand and new strategic partnerships helped drive 10% year-on-year organic growth in revenues1. Investments in automation and AI are helping to improve quality and productivity across the business.
