Louise Watson (LW): Hello and welcome to Navigating the Noise, a podcast by Natixis Investment Managers, where we bring you insights from our global collective of experts to help you make better investment decisions. I'm Louise Watson, and today I'll be joined by Jens Peers. Jens is the CIO of Mirova US and Portfolio Manager of Mirova's Global Sustainable Equity Strategy. Jens is also a true global citizen. He's from Belgium but lives and works in the US and visits other areas of the world to meet companies and investors. We're looking forward to welcoming him back to Australia in October.
Jens, welcome! Great to chat to you again. We're just coming out of the Northern Hemisphere summer, and I understand it was very hot in many parts of Europe. How did you spend your summer, and how did you manage to escape that heat?
Jens Peers (JP): Hi, Louise. Thanks for having me. So, it was really hot in Europe, but luckily, I spent most of my summer in the US. It's always warm here as well. But I'm just back from a few days— we love camping. I put a camper on the ferry to Martha's Vineyard and spent a few days there cycling around. That really helps deal with the heat.
LW: Awesome. That sounds like a great way to spend summer. Now, let's get right into the portfolio. You describe your global equity investing strategy as multi-thematic. It is centred on four big megatrends—long-term structural changes to the world. Can you briefly tell us about these four trends?
JP: And you're right. We create our portfolios around four key transitions - transitioning from where we are today to where we will be in the next decade or few decades. Those transitions are very much aligned with what the World Economic Forum has also seen as the big longer-term trends. They're centred around demographic changes and transitions, which we need to adapt to in terms of how the world will look from a demographic point of view. Then there are technological, environmental, and governance transitions - how you organise a broader economy, which will also change gradually over the next few decades. We invest along those key transitions in the portfolio.
LW: And roughly what percentage of your portfolio is invested in each megatrend at the moment? Do you have set limits or targets for each?
JP: We don't really have set targets. We create the portfolio from the bottom up, based on stock opportunities and valuation opportunities from these stocks as well. So, the breakdown of our portfolio along those megatrends is really dependent on how we see those opportunities, and no surprise that over time that has changed. While we were a lot more focused on environmental factors, let's say about ten years ago, we're now a lot more biased towards technology. Technology as a transition and the companies that offer solutions there roughly represent about 45% of the portfolio today. That's followed by the environmental transition, mainly companies dealing with energy and resources like water, which is about a bit under 30% today. The demographic transition is around 20%, and then governance and cultural transitions make up just over 5% today.
It has to be said that some companies obviously contribute to and benefit from multiple trends. For instance, under that governance trend, dealing with diversity is very important, and companies like NVIDIA, which we obviously play as a function of that technological transition towards a world with more AI applications, have also come on our radar because of their strong diversity policies. A lot of these companies play multiple themes at the same time. But, you know, technology followed by environmental, then demographic trends, and then governance— that's what we have today in terms of weight.
LW: Technology, particularly AI, has been the hottest investment theme of recent times. There are concerns about overinflated valuations, though, and comparisons to booms and busts of the past, like the tech wreck of the early 2000s. How exposed are you to the tech sector, and how do you manage the risks of investing in tech, robotics, and AI alongside all these exciting opportunities?
JP: It is true that there are many similarities today, specifically given the outperformance of mainly the AI names in the past couple of months - many similarities to the dot-com crisis. Ultimately, that turned out to be a bubble that burst. But don't forget that the Internet really drove big changes in our economy, and even throughout that bubble back in those days, the most important companies today and the best performances over the last 20 years were actually found in companies with exposure to that theme.
In terms of the boom and bust after that, we see many similarities. The market was back then and certainly is today very concentrated in terms of the highest weights of individual companies and themes and sectors, like tech. Right now, valuations of many of those AI names, specifically a lot of startups, are very high, and expectations are huge as well. The timing, even if AI is really changing our world significantly, as we do expect, is also dependent on many other things that need to be done, like investing in better energy infrastructure, getting access to water, etc.
We've seen the same happening about 25 years ago, where there was a boom first, followed by a bit of a bust. There are also differences. The main companies active in this space now, compared to 25 years ago during the dot-com crisis, are very well capitalised. They have strong balance sheets, generate a lot of cash flow, and continue to invest significantly in this area, mainly through the creation of that free cash flow. That should create a bit of a buffer on that valuation.
But it's true that these AI companies have outperformed the other part of the technology industry, and specifically, we believe software companies today are very attractive after a strong underperformance versus those AI companies and the semiconductor companies that also benefit from AI. The performance gap and the valuation gap between software companies and the market - those companies that the market thinks might actually suffer from AI and face competition from AI - are at a very high level. So, in our portfolio, we have some exposure to some of those semiconductor names, like NVIDIA and Taiwan Semiconductor, but we also have software companies in the portfolio, like Salesforce, where we see a lot more valuation opportunities, and there's certainly no question about bubble valuation.
LW: AI is very closely tied to cloud computing, and we've seen huge profits and growth in cloud computing in recent months. How far into that move to cloud computing do you think we are?
JP: You know, AI depends a lot on data, and the way that the data models or the AI models work depends heavily on access to the data in the cloud as well. Roughly around 50% to 60% of all the data in the world today is stored in the cloud already.
