In this episode, Cem Karsan returns to Excess Returns to break down the market through the lens of liquidity, reflexivity, and options-driven market structure. We cover why he believes we are in a bubble but still early in its trajectory, the mechanics behind today’s volatility dynamics, the role of AI spending in sustaining the cycle, and why traditional 60/40 portfolios may face major challenges in the years ahead. Cem also explains how investors should think about tail risk, true diversification, and building portfolios for a world where liquidity flows dictate outcomes.
