Abstract
The VIX is a proxy for the implied volatility, computed con- sidering Standard & Poor’s 500 Index data. It widely regarded as a mea- sure of turbulence in U.S. and global financial markets. Hence, forecasting the VIX is essential for both portfolio managers and policy makers. By modeling the S&P 500 Index as a multifractional Brownian motion, we exploit the relationship between its Hurst exponent and the volatility to predict the VIX by a Distributed Lag model.| File | Dimensione | Formato | |
