We study the dynamics and cross-sectional properties of the variance risk premia embedded in options on stocks and indices, approximated by the synthetic variance swap returns. Several important stylized facts and contributions arise. First, variance risk premia for indices are systematically...

We study the cross-section of stock options returns and find an economically important source of mispricing in individual equity options. Sorting stocks based on the difference between historical realized volatility and market implied volatility, we find that a zero-cost trading strategy that is...

The slope of the implied volatility term structure is positively related to future option returns. We rank firms based on the slope of the volatility term structure and analyze the returns for straddle portfolios. Straddle portfolios with high slopes of the volatility term structure outperform...

We use quantile regression to investigate the short-term return-volatility relation between stock index returns and changes in implied volatility index. Neither the leverage hypothesis nor the volatility feedback hypothesis effectively explains the asymmetric return-volatility relation. Instead,...

Pushing models to extremes can expose output biases that stem from underlying assumptions. In the case of industry standard option valuation models, long term, high volatility securities provide a stress test vehicle. For instance, in evaluating a stock with 60% volatility, industry standard...

We study the fitting of the euro yield curve with the Longstaff and Schwartz (1992) (LS) two - factor general equilibrium model and the Schaefer and Schwartz (1984) (SS) two-factor arbitrage model of the term structure of interest rates. The Cox, Ingersoll, and Ross (1985b) (CIR) one-factor...

This article prices caps and swaptions in the Spanish market using the Vasicek, Cox, Ingersoll, and Ross and Hull and White (HW) models. Derivative prices obtained with the Vasicek and CIR models estimated from time series data are very similar, but they differ substantially from the values...

We develop an option pricing model for calls and puts written on leveraged equity in an economy with corporate taxes and bankruptcy costs. The model explains implied Black-Scholes volatility biases by relating them to the firm's structural characteristics such as leverage and debt covenants. We...
