Implied and Realized Volatility: Empirical Model Selection
نویسنده
چکیده
The paper studies the nonparametric connection between realized and implied volatilities. No-arbitrage identities and comparison inequalities are found. We formulate the multi-factor trading system on the volatility scale. To empirically determine the number of factors, we develop a high frequency analysis for sequential F-testing. We also design a cross validated estimate of quadratic variation.

Volatility Puzzles: A Unified Framework for Gauging Return-Volatility Regressions∗
This paper provides a simple unified framework for assessing the empirical linkages between returns and realized and implied volatilities. First, we show that whereas the volatility feedback effect as measured by the sign of the correlation between contemporaneous return and realized volatility depends importantly on the underlying structural model parameters, the correlation between return and...
متن کاملOption-Implied Correlations and the Price of Correlation Risk∗
We provide evidence that the risk of changes in equity correlations is priced, using data on S&P100 options and options on all the stocks in the index. We develop a model for equity prices with priced correlation risk, which generates (i) option-implied correlations that exceed realized correlations, (ii) a zero difference between implied and realized equity variances, (iii) endogenous stochast...
متن کاملThe Relation between Implied and Realized Volatility of S&P 500 Index
This paper studies the relation between implied and realized volatility by using daily S&P 500 index option price over the period between January 1995 and December 1999. In particular, we want to test the how different measurement errors affect the stability of this relationship. Two sources of measurement errors are considered. The first one is the measurement error in realized volatility. Fou...
متن کاملModel-Free Implied Volatility and Its Information Content
We implement an estimator of the model-free implied volatility derived by Britten-Jones and Neuberger (2000) and investigate its information content in the S&P 500 index options. In contrast to the commonly used Black-Scholes implied volatility, the model-free implied volatility is not based on any specific option pricing model and thus provides a direct test of the informational efficiency of ...
متن کاملThe Role of Implied Volatility in Forecasting Future Realized Volatility and Jumps in Foreign Exchange, Stock, and Bond Markets
We study the forecasting of future realized volatility in the foreign exchange, stock, and bond markets from variables in the information set, including implied volatility backed out from option prices. Realized volatility is separated into its continuous and jump components, and the heterogeneous autoregressive (HAR) model is applied with implied volatility as an additional forecasting variabl...
