We price derivatives defined for different asset classes with a full stochastic dependence structure. We consider jointly geometric Brownian motions and mean-reversion processes with a a stochastic variance-covariance matrix driven by a Wishart process. These models cannot be treated within the...

This paper introduces a novel method for pricing commodity index derivatives consistently with market prices of derivatives on single commodities. We discuss the Black, mean-reversion and local volatility pricing models with special attention paid to the parameterization of volatility surfaces....

With the transitions to overnight benchmarks as the main benchmarks in some currencies, futures based on overnight rates are becoming more common. The most traded futures on overnight rates settle against compounded rates. The pricing of those futures requires some convexity adjustments with an...

A new measure of hedging pressure in commodity options markets—commercial hedgers’ net short option exposure—predicts option returns and changes in the slope of implied volatility curves. Puts are more expensive, and calls are cheaper, when values of option hedging pressure are greater....

We show that LME's (London Metal Exchange) listed forward contracts can be valued using usual formulas for forward contracts and that LME's listed Options, though legally American, are correctly treated as European Options

Adjusting the correlation matrix plays an important role in risk management as well as option pricing. We usually … adjust the correlation matrix by directly changing the correlation coefficient in the correlation matrix. However, there is a … chance that the adjusted correlation matrix is not valid. In this paper, we present a new algorithm for adjusting the …
