SI375: CTAs After the Walls Come Down ft. Rob Carver

Rob Carver returns for a conversation that quietly questions the foundations. Is trend following an edge - or just a reward for holding discomfort others can’t? From the role of skew in shaping outcomes to the blind spots in most robustness frameworks, Rob and Niels takes you through the mechanics with uncommon clarity. Listener questions open up the deeper layers: when volatility targeting helps, when it hurts, and why Sharpe Ratios can mislead. They end with a shift that may matter more than it seems: CalPERS moving to a Total Portfolio Approach. Not just a new framework - potentially a new lane for CTAs.
