For many interest rate exotic options, for example options on the slope of the yield curve or American featured options, a one factor assumption for term structure evolution is inappropriate. These options derive their value from changes in the slope or curvature of the yield curve and hence are...

It is natural to assume that interest rates mean-revert, and natural consequence of this is that long forward rates are asymptotically constant. However, from US Treasury STRIPs data, forward rates slope increasingly downwards, and do not attenuate in volatility, as maturity increases beyond...

We construct portfolios of Samp;P500 futures and their associated options, which are Delta (price) and Vega (volatility) neutral. These systematically earn negative abnormal returns, and suggest that out of the money puts are too expensive, relative to out of the money calls. We give evidence...

This paper first designs an efficient procedure to value Credit Default Swap Index tranches using an intensity-based model. The tranche spreads are effectively explained by a three-factor version of this model, both before and during the financial crisis of 2008. We then construct tradable...

This study intends to find out whether or not the Nikkei 225 evolves over time in accordance with the following four widely used processes for determining stock prices: random walk with a drift, AR(1), GARCH(1,1), and GARCH(1,1)-M. Given the fact that, in actuality, we have but one sample of...

Since its introduction in 1973, the Black-Scholes model has found increasingly more resistance in application. In order to use Black-Scholes to price any option, one needs to know the implied volatility surface. The existence of such surface is an evidence of misspecification of the model. In...
