Exploring option pricing with mean-reversion jump diffusion
Yijun Du explores option pricing with a mean-reversion and jump-diffusion – or MJ – model, using Monte Carlo simulation. We find that jumps can increase the call price, a higher mean-reversion rate lowers the call price and the time to maturity has…
VAR you can rely on
Analytical and simulation-based methods often appear as rivals, but many real world problems are best served by judicious combinations of both approaches. In a first of a pair of computationally themed papers, Rabi De and Tanya Tamarchenko present a…

Calculating portfolio loss
For credit portfolios, analytical methods work best for tail risk, while Monte Carlo is used to model expected loss. However, products such as CDOs require a model for the entire distribution. Sandro Merino and Mark Nyfeler meet the challenge by…
Using Bayesian networks to predict op risk
By combining qualitative and quantitative data, Bayesian networks offer the perfect solution to the compelling need for an integrated approach to operational risk management, say Martin Neil and Ed Tranham.
Modelling weather-sensitive electrical loads
Here Véronique Bugnion, Aram Sogomonian and Glen Swindle introduce a new methodology for forecasting and jointly simulating temperature and electrical load
Risk and probability measures
Although its drawbacks are well known, VAR has become institutionalised as the market risk measure of choice among trading firms and regulators. Now there is a growing feeling that a reappraisal is overdue, exemplified here by Phelim Boyle, Tak Kuen Siu…
On the log-log linearity of the size distribution of growth stocks
Mauboussin & Schay (2000)1 discovered an almost linear relationship between the logarithm of the market capitalisation and the logarithm of the rank for growth stocks. Kou & Kou (2001)2 proposed an explanation for this observation based on the theory of…
A two-factor mean-reverting model
Commodity markets exhibit multi-factor behaviour as well as mean reversion. Building upon their previous paper, David Beaglehole and Alain Chebanier conclude the current Masterclass series by developing a two-factor mean-reverting model for crude oil…
The maturity effect on credit risk capital
In a mark-to-market approach to credit risk capital, ratings or spread volatility has the effect of making longer-maturity loans more capital-intensive. This is incorporated in the current Basel II proposals via a maturity adjustment factor. Arguing that…

Mean-reverting smiles
Commodity markets such as crude oil exhibit mean reversion as well as option smiles. David Beaglehole and Alain Chebanier meet this challenge, constructing a model suitable for pricing exotic options in these markets
