This episode analyzes implied volatility trading strategies, focusing on the persistent overpricing of volatility and its implications for profitability. It explains that short volatility strategies, while seemingly profitable due to this overpricing, are positively correlated with equity returns, partially offsetting gains. The document explores various factors contributing to volatility overpricing, including demand for hedging products and structured product flows, suggesting this overpricing is unlikely to disappear soon. Furthermore, it examines the use of long volatility as a hedge, concluding it's generally ineffective due to overpricing and less-than-perfect correlation with equity markets. Finally, the text details how structured products can exacerbate volatility fluctuations, creating a "vicious circle" effect.
