Historical models are being quite used in the value at risk (VaR) estimation due to the fact that many returns of financial assets cannot be described by a theoretical distribution. In these models, each observation of the past can be a possible scenery and for each scenery there is a price for...

Options strategies are combinations of transactions involving options on the same underlying asset or simultaneous positions on those derivatives assets and the underlying asset. Such transactions create new investment opportunities and different risk exposures, leading to specific capital...

The Value at Risk calculation for options has a lot of difficulties. The non-normality and the non-linearity of these assets cause sufficient unaccuracy in this measurement, mainly for the parametric models. The purpose of this article is to analyze the results of the VaR estimate for a...

We develop a tractable structural model to estimate a firm's default probability by modeling its asset and debt behavior. The model incorporates jump factors. For a set of Brazilian large corporations, we compare the structural model results to the default probabilities predicted by a survival...

Pricing interest rate derivatives is a challenging task that has attracted the attention of many researchers in recent decades. Portfolio and risk managers, policymakers, traders and more generally all market participants are looking for valuable information from derivative instruments. We use a...

The Duan Options Pricing Model is an alternative to the Black & Scholes Model (B&S), but considers the heteroskedasticity and the non-normality of the asset-returns. This study analyzes the performance and the characteristics of this model when applied to the Brazilian market, specifically on...

The importance of risk management has been highlighted by the series of disasters related to the application of derivatives and by the common sense in needing to cover these operations with capital allocation. However, not much agreement exists concerning the methods for calculating the capital...
