Volatility Forecasting and Volatility Risk Premium

Equity Market Volatility and Expected Risk Premium

This paper revisits the time-series relation between the conditional risk premium and variance of the equity market portfolio. The main innovation is that we construct a measure of the ex ante equity market risk premium using corporate bond yield spread data. This measure is forward-looking and does not rely critically on either realized equity returns or instrumental variables. We find strong ...

The Volatility Premium

Implied option volatility averages about 19% per year, while the unconditional return volatility is only about 16%. The difference, coined the volatility premium, is substantial and translates into large returns for sellers of index options. This paper studies a general equilibrium model based on long-run risk which in an effort to explain the premium. In estimating the model on past data of st...

Forecasting Volatility

Volatility Forecasting and Interpolation

Forecasting volatility is important to financial asset pricing because a more accurate forecast will allow for a more accurate model to price financial assets. Currently the VIX is used as a measure of volatility in the market as a whole, but a major issue with this is that it is calculated based on manually traded options on the S&P 500. Another method of forecasting volatility is that of solv...

Delta-Hedged Gains and the Negative Market Volatility Risk Premium

We investigate whether the volatility risk premium is negative by examining the statistical properties of delta-hedged option portfolios (buy the option and hedge with stock). Within a stochastic volatility framework, we demonstrate a correspondence between the sign and magnitude of the volatility risk premium and the mean delta-hedged portfolio returns. Using a sample of S&P 500 index options,...
