How The Vanna Trade Reshapes Market Volatility
Summary
This episode explores the "vanna trade," a mechanical linkage between interest rates and options hedging that drives market flow. The hosts explain how rising 10-year yields force market makers to adjust delta hedges aggressively, creating buying pressure even when volatility drops. They discuss how this dynamic impacts retail investors, widens bid-ask spreads, and affects small-cap stocks more severely due to floating-rate debt sensitivity. Finally, the episode offers actionable advice on using out-of-the-money options to minimize vanna exposure and improve portfolio stability.
