European healthcare stocks, which had been leading the market for much of 2024, now face significant challenges as they head into the new year. The sector’s recent decline, particularly in the last few months, is partly attributed to concerns over US politics and upcoming high-stakes trial results for new drugs.
Earlier this year, European healthcare stocks, especially those in the Stoxx 600 Health Care Index, were outperforming other sectors. However, since their peak in late August, the index has dropped by 12%. This decline was partly driven by a sharp pullback in Novo Nordisk’s stock after a period of extraordinary gains, as well as concerns surrounding AstraZeneca due to compliance issues in China.
One key factor weighing on the sector is uncertainty about US healthcare policy. The nomination of health officials by president-elect Donald Trump, including a vaccine skeptic, has already caused a selloff that knocked healthcare stocks from their previous leadership position to a more middle-of-the-road performance. With the US accounting for a significant portion of revenue for Europe’s top pharmaceutical companies—ranging from 40% to 55%—changes in American healthcare policy could have a large impact on investor sentiment. However, fundamental changes in US policy are still highly uncertain, as healthcare systems are notoriously hard to modify.
For many investors, healthcare stocks had previously been an attractive defensive play amid Europe’s grim economic outlook. In addition, the hype surrounding weight-loss drugs had pushed valuations higher. However, this momentum has slowed, with concerns over US policy now taking center stage.
The healthcare sector’s heavy reliance on the US market is evident in the financial reports of Europe’s top six pharmaceutical companies, which rely heavily on American revenue. Barclays analyst Emily Field anticipates a “more challenging outlook” for European pharma as the year progresses. Likewise, analysts at HSBC, including Rajesh Kumar, emphasize that the economics of drug development would be severely impacted without the US market.
The healthcare industry was further rattled by the nomination of Robert F. Kennedy Jr. as head of the Department of Health and Human Services by president-elect Trump. Kennedy, a well-known vaccine skeptic, sparked a sharp decline in vaccine and pharma stocks in both the US and Europe.
