This study discusses how to compute and forecast long-term stock return volatilities, typically with a 5-year horizon or longer, using credit derivatives, and how such volatilities can be used in different areas ranging from the valuation of employee stock options and other long-term derivatives...

This paper describes how credit default swaps could be employed to create performance based executive compensation portfolios that reflect the value of a firm’s debt as well as equity; i.e. the total value of all a firm’s assets. So-called Asset Value Unit (AVU) compensation portfolios are...

In this paper we employ the news aggregator GoogleTM News to demonstrate a strong link between the volatility in the stock market and the amount of news available to market participants. The paper also highlights some other areas, in finance and elsewhere, where news aggregators could be useful.

This paper focuses on the many extreme credit default swap spread movements observed during the recent credit crisis and on how the tails of the spread (and price) change distribution significantly differ from those of the normal distribution even for diversified credit derivatives portfolios....

This paper investigates the pricing bias in the Swedish OMX-Index Option market and how a stochastic volatility affects European call option prices. The market is purely European and without dividends for the period studied. A CIR square-root process for the volatility is estimated with...

The growing interest in management of credit risk and estimation ofdefault probabilities has given rise to a range of more or lesselaborate credit risk models. Hall and Miles (1990) suggests an approachof estimating failure probabilities based solely on stock market prices.The approach has the...

This paper introduces a simple continuous measure of credit risk that associates to each firm a risk parameter related to the firm's risk-neutral default intensity. These parameters can be computed from quoted bond prices and allow assignment of credit ratings much finer than those provided by...

This paper applies the Merton (1974) default probability model to the firms in the SET-50 index at the Stock Exchange of Thailand (SET). It also examines the rela- tionship between a firm's default probability and firm-specific characteristics like size and book-to-market ratio, and whether...

In this paper we describe a simple way of analytically computing entire ìterm structures of default probabilities using information embedded in the corporate bond market data. This market-based approach of estimating the creditworthiness of firms gives probabilities of default at various...

Financial risk management typically deals with low probability events in the tails of asset price distributions. In order to capture the behavior of these tails, one should therefore rely on models that explicitly focus on the tails. Extreme value theory (EVT) based models do exactly that, and...
