The model-free measures and the volatility spread

Pages 1829-1833 | Published online: 21 Apr 2010
 

Abstract

In this article, we empirically investigate the relationship between realized and risk-neutral volatilities by applying the model-free measures to FTSE-100 index and index options from April 1992 to March 2005. Based on the deviation between the risk-neutral and the physical volatilities, we estimate the volatility spread through the Generalized Method of Moments (GMM) and reveal the volatility risk aversion.

Notes

1Egelkraut and Garcia (Citation2008) adopt a different model-free methodology to reveal option-implied volatility.
