Responsible Investment Research

White Stag Investing is a research platform for responsible investments. The research follows a philosophy of investing where sustainability is a source of value and stability in the long-term.


Current environmental and social trends are affecting our economic tissue and renders the investment landscape more challenging to navigate. By understanding and facing these new risks, investors arm themselves with the necessary tools to avoid new pitfalls in their investment perspectives.


Taking this responsibility for these new challenges is a also source of value for investors. Our economies are heavily reliant on nature and its ecological services, yet very few recognize this fact in their investment decisions. This represents a set of unmaterialised opportunities for investors by recognising new premiums in their portfolios, and investing in game-changing innovation to face the challenges of the 21st century. Integrating this in the core of the portfolio construction brings new sources of performance and diversification to the table.


Following this approach, the impact is finally and naturally embedded at the core of the investment strategy, further rewarding investors with meaning in their allocations.

Nicola Lei Ravello

After 7 years as an investment analyst in the hedge funds industry, I've started covering sustainable finance on my own initiative since early 2019. I  have been heavily engaging the (sustainable) finance community  how to recognize sustainability as a long-term source of value for investments, and how to strategically integrate it in their portfolios. I've researched the most promising sustainable themes investors can invest in and analyzed their investment universes. I am working as an independent research provider in that field, serving many established institutions in their strategic and sustainable analysis, as well as frontline investors seeking new insights and value in the realm of sustainability.  I have a in Economics from HEC Lausanne and a in Finance from the University of Zürich. I am finally an avid cook, karateka and windsurfer.
