Investment philosophy and approach  

We take a global macroeconomic perspective, uncovering key themes that will shape the future. Our thematic approach means we focus on defining a particular opportunity and the drivers first. Then we look at the best methods to capture the investment opportunity.

View the global economy with a macro lens, identifying key themes in global investment markets. 

Uncover the beneficiaries of these key themes, before they have the potential to become widely recognised.

Define the structural, economic and regulatory drivers to determine the opportunity and key risks.

Identify companies, industries or managers who can leverage these opportunities.
