In this episode of The Grant Williams Podcast, I welcome my good mate Dave Dredge of Convex Strategies for a fascinating conversation about fragility, portfolio construction, and why so many traditional investment frameworks are no longer fit for purpose. Using everything from London Tube strikes to Mandelbrot’s work on volatility clustering, Dave explains why markets should be understood not as stable systems occasionally disrupted by shocks, but as inherently fragile structures where hidden stresses build quietly over time before suddenly erupting. At the heart of our discussion is the “total portfolio approach”—a growing institutional framework that focuses less on the standalone return of individual assets and more on how each position contributes to the resilience, correlation profile, and survival of the portfolio as a whole in an increasingly unstable world.
