Highlights

Fun times yesterday at the 11th edition of the summer Méchoui organized by FIAMtl held at the Paddock Belvedere of Parc Jean-Drapeau.

Interesting panels included former White House intelligence briefer Michelle DiGruttolo, who highlighted through compelling examples that climate change as a driver of geopolitics is underappreciated. She also reminded us that we are moving back to a multi-polar world with all its risks.

William J. Kelly, CAIA, CEO of the CAIA Association, quoted Harry Markowitz with the famous saying that "diversification is the only free lunch in investing..." but added that "there is a cover charge" in performing thorough due diligence and selecting the right managers. I couldn't agree more.

Congratulations to Claude Perron and the organizers!
