From martingales to ANOVA: Implied and realized volatility.

From martingales to ANOVA: Implied and realized volatility. - 129 p.

Chair: Per A. Mykland.

Implied volatility and realized volatility are two different ways to describe the variations in the price returns of financial data. Their relationship, however, remains unclear in the literature. In this research, we establish a theoretical connection between these two types of volatility under the no-arbitrage rule. We find that depending on the smoothness level of the cumulative implied volatility, the implied-realized association can be represented differently.

520 $a Implied volatility and realized volatility are two different ways to describe the variations in the price returns of financial data. Their relationship, however, remains unclear in the literature. In this research, we establish a theoretical connection between these two types of volatility under the no-arbitrage rule. We find that depending on the smoothness level of the cumulative implied volatility, the implied-realized association can be represented differently.
520 $a Moreover, this relationship can be tested empirically. Using a non-parametric approach and martingale decomposition, on the one hand we are able to obtain estimators for the two volatilities. We examine the statistical properties of the procedure, in particular, how to set confidence intervals, and we investigate the impact of the estimation scheme on trading error. On the other hand, we can combine our theoretical findings with the ideas of ANOVA to analyze several quadratic variations in incomplete financial markets. This latter method decomposes the variation content implied from an option into two parts, the variation “observed” from historical stock returns, and the residual variation (< <italic>Z </italic>, <italic>Z</italic> >) which may contain the variation from one or several extra instruments. A main device in the theoretical analysis is finding the small interval asymptotic distribution for the estimation error of < <italic>Z</italic>, <italic>Z</italic> >. Finally we discuss the implications on delta hedging and on the selection of volatility structure. We also carry out numerical experiments and a data analysis with S&P500 data.
