Purpose – In June of 2001, Tokyo Electric Power Company (TEPCO) and Tokyo Gas Supply Company (TGSC) made a zero-cost risk swap contract on the average temperature of August and September of 2001 in Tokyo for their adverse situations. This is an exchange of two options on the average...

The purpose of this paper is to serve as a guide for students’ use of actual data for risk and return calculations. The study of stock return risk has been of interest to investors and academics for several decades. Early discussion of the mean-variance framework described the rationale...

The paper presents a consistent approach to the modeling of general and specific market risk as defined in regulatory documents. It compares the statistically based beta-factor model with a class of benckmark models that use a broadly based index as major building block for modeling. The...

We discuss the precision with which financial models are handled, in particular optimization models. We argue that precision is only required to a level that is justified by the overall accuracy of the model, and that this required precision should be specifically analyzed in order to better...

In the present paper we give some preliminary results for option pricing and hedging in the framework of the Bates model based on quadratic risk minimization. We provide an explicit expression of the mean-variance hedging strategy in the martingale case and study the Minimal Martingale measure...

Purpose – The purpose of this article is to discuss a Black-Scholes-Merton (BSM)-based market approach to quantify the default risk of publicly-listed individual companies. Design/methodology/approach – Using the contingent claim approach, a framework is presented to optimally use stock...
