Cover Story: The authors in this paper propose a new proxy for the unobserved volatility process. Specifically, they obtain an implied volatility process by calibrating a general stochastic volatility model to options' data and their sensitivities. In this plot, the estimated volatility proxy for the S&P 500 index is plotted along with a rescaled VIX index. In the same paper, the authors also investigate the roughness of the volatility process by estimating its long memory/roughness parameter, the so-called Hurst index. They conclude that the volatility of the index exhibits a rough behavior even with low-frequency observations. View this paper
