Abstract

In this paper, Malliavin calculus is applied to arrive at exact formulas for\nthe difference between the volatility swap strike and the zero vanna implied\nvolatility for volatilities driven by fractional noise. To the best of our\nknowledge, our estimate is the first to derive the rigorous relationship\nbetween the zero vanna implied volatility and the volatility swap strike. In\nparticular, we will see that the zero vanna implied volatility is a better\napproximation for the volatility swap strike than the ATMI.\n
