Stephen Yiu is the Chief Investment Officer at Blue Whale Capital and Lead Manager of the Blue Whale Growth Fund.
Stephen co-founded Blue Whale Capital with Peter Hargreaves, co-founder of Hargreaves Lansdown, in 2016. The Blue Whale Growth Fund was launched in September 2020 and is a long-only global equity fund focusing on developed markets.
Stephen adopts a high conviction, active approach based on
bottom-up, fundamental research.
Recent developments in Iran have understandably unsettled markets. Periods like this tend to bring volatility, often driven more by sentiment than by any immediate change in underlying fundamentals.
From our perspective, the key question is simple: has the earnings trajectory of the businesses we own changed?
In short, we do not believe it has.
Many of the structural growth drivers within the portfolio remain firmly intact. The adoption of GLP-1 therapies, led by companies such as Eli Lilly, continues to expand globally. Investment in AI infrastructure (across NVIDIA, Broadcom, Vertiv and SK Hynix) remains a priority for businesses and governments alike. Meanwhile, demand for biologics manufacturing, supported by Sartorius and Danaher, continues to grow in line with long-term healthcare trends.
These structural forces are accelerating, not slowing.
Against this backdrop, recent share price weakness appears increasingly disconnected from business fundamentals. For long-term investors, this can present an opportunity to access the same earnings streams at more attractive valuations.
Whilst much of the portfolio we believe is insulated from such geopolitical developments, the Fund’s defence exposure, including Leonardo and Honeywell (a new addition to the Top 10), may be a beneficiary as we see increased demand as governments reassess security priorities.
It is also important to recognise that this is not the first time markets have faced sharp macro uncertainty during the life of the fund. Since inception, we have navigated events including trade tensions under President Donald Trump, the COVID-19 pandemic, the war in Ukraine, and the rapid global interest rate tightening cycle. In each instance, periods of volatility have allowed us to refine the portfolio – emerging with a more resilient collection of businesses and a stronger foundation for long-term outperformance.
As business analysts, our focus remains firmly on the earnings trajectory of each company we own. We continually assess our holdings in the context of the evolving macroeconomic environment, using it as an overlay to test whether those earnings paths remain intact. Where we believe macro developments could materially alter the long-term outcome for a business, we will reassess its position in the portfolio. This discipline ensures that our conviction is grounded in fundamentals, not sentiment.
Finally, a brief word on gold. While prices have softened in recent weeks, it is important to remember what has driven its strength: concerns around fiscal sustainability across developed markets and the resulting demand for hard assets. If anything, heightened geopolitical tension reinforces these underlying dynamics rather than diminishes them.
In periods like this, it is easy to be drawn into short-term noise. Our approach remains unchanged: focus on high-quality businesses with durable earnings growth, and allow this discipline – rather than headlines – to drive outperformance over the long term.
