If you pick up a newspaper today, it is likely that you will find an article either proclaiming or disputing the existence of an artificial intelligence (AI) bubble. As the chart below shows, in the week commencing the 17 October, 1,100 articles globally included the term ‘AI bubble’.

The dizzying valuations and speculative corporate investments in AI are enough to make anyone feel queasy. OpenAI recently committed to spend more than $1trn over a five-year period, around 100x its annual recurring revenue.
Investors therefore, find themselves in a dilemma. While many may still have a pervasive fear of missing out, an increasing number are concerned about investing in a bubble that could pop at any moment and are looking for more attractively priced opportunities.
Healthcare offers the potential for tech-like growth at a far more reasonable price
We believe healthcare offers an attractive combination of significant earnings growth potential and a historic valuation discount.
The technology sector is forecast to grow earnings at a 25% compound annual growth rate (CAGR) through to 2027. It may surprise many to realise that healthcare earnings are not far behind with a forecast 22% CAGR over the same period.
And yet, despite the similar earnings outlook, the healthcare sector hasn’t traded at such a deep discount to technology stocks since the financial crisis.

At prevailing prices, the growth potential offered by the tech sector is 50% more expensive than health care – something a price earnings growth (PEG) ratio can tell you.

Reasons for the valuation gap appear to be receding
As we noted in July this year and in our more recent discussion of the Not-So-Magnificent-17, a number of factors drove the emergence of the healthcare sector’s discount, many of which we believe are now moderating.
In particular, the risk of changes to US drug pricing policy was at the forefront of many investors’ minds earlier this year. More recently, a number of pharma companies have made deals with the US administration, potentially taking aggressive drug price reductions off the table while both sides can claim victory.
At the same time, the FDA continues to approve new therapies at pace, with 35 new drugs approved this year to date. This is roughly in line with the 38 drugs approved at the same point in 2024, showing innovation in the sector remains vibrant.
Although these updates are specific only to pharma, the increased clarity has had a positive effect on supply chains too. Some tools companies, which provide the technology and services to help bring therapies to market, are seeing a marked increase in activity from their biopharma customers.
We believe this could be a leading indicator for upgraded earnings outlooks for that sub-sector.
