Baptiste Langle from Dubly Transatlantique Gestion is our Advisor of the Month

Baptiste Langle first started his career as a portfolio management assistant at Dubly Transatlantique Gestion, the asset management subsidiary of Banque Transatlantique. After a short move to London as a sales trader, he then returned to Dubly Transatlantique Gestion as a multi-asset portfolio manager, where he still works today, marking 10 years in May 2026.

Looking back at your journey in asset management, which defining moment or decision most shaped the advisor you are today?

I started as an assistant and buy side analyst and understanding the stocks really helped me get into fund selection in order to deeply understand the moves fund managers’ are making and the reasons behind their stocks’ choices.

What is a lesson you learned early in your career that still influences how you manage portfolios or advise clients today?

Not moving is also an act of portfolio management. Indeed, staying calm and keeping my positions for the long run really helped me avoid saloon doors.

How has your investment philosophy evolved as markets have become more data-driven, faster, and increasingly influenced by technology?

I focus more on the fundamentals to make sure that I am selecting the right stocks. In terms of funds, I turned a small part of my allocation from concentrated long term fundamental funds into more index and quant funds.

Is there a widely held market assumption today that you believe deserves more scrutiny? Why?

I do make sure the companies I am investing in have strong free cash flow generating models, over all with AI in order to not reproduce the 2000’s bubble.  I am watching the PEG in the AI sector but only investing in beneficiary companies. Finally, I have a preference in the AI sector for companies that already have an established business model and spread a part of their business model into AI.

Which long-term structural trend — demographic, technological,
geopolitical, or monetary — do you believe will most reshape asset allocation over the next decade?

I think there are a few groundswell that we should watch : the spread of AI into the industrial sector and the fact it might bring back a new way of addressing ESG, the geopolitical tensions and the new ways of war like drones making wars quicker with less human losses and finally the speed of market crashes and recoveries increasing the ease to take saloon doors if we are not watching.

What is a risk scenario that investors are currently underestimating, and how should advisors prepare for it?

A glass ceiling in the growing demand of microchips. Indeed, at the moment we are still in the equipment phase but we should move over the next few months/ quarters into a phase of optimization because we cannot push the datacenter walls until a certain point. Since the market starts to doubt about the economic viability of AI, the hyperscallers will probably try to optimize the way they use their current datacenters which could lower the demand’s growth and create a short crash on DRAM and microchips’ prices. We prepared this scenario by having a watchlist of software companies and funds ready to switch to.

Beyond performance, what do you believe builds lasting trust between an advisor and their clients?

Communication is key and overall listening to the client’s needs. What will keep us from being replaced by AI agents is our empathy, our capability to listen to our clients more than just hear them and adapt over the long run our strategy on the path. I have the chance to say that I still work with most of my clients that I advise from day one!

For young professionals entering asset management today, what mindset or habit is most important to build a long-term, credible career?

Being rigorous, constant and very well organized. Rigor will make your clients and colleagues rely on you. Constancy will take you to the next level and organization will help you get there.

When you step away from markets, what hobbies or passions help you recharge — and do they influence the way you approach investing in any way?

I like outdoor sports like hiking, alpinism and canoeing because it makes me focus on doing the right movements, not overthink and admire splendid landscapes.
