This paper presents a simulation study of hedging long-dated futures options, in the Rabinovitch (1989) model which assumes correlated dynamics between spot asset prices and interest rates. Under this model and when the maturity of the hedging instruments match the maturity of the option,...

The implied volatilities provided by OptionMetrics in the IvyDB database suggest substantial deviations from put-call parity that do not really exist. In S&P 500 options, artificial deviations occur because OptionMetrics uses non-synchronous index and option prices and an average implied...

Hedging at-the-money digital options near maturity, remains a challenge in quantitative finance. In the present work, we carry out a hedging strategy by means of a bull spread. We study the probability of super- and sub-hedge the digital option and minimize the probability of a sub-hedge...

In this paper, we introduce two methods to solve the American-style option pricing problem and its dual form at the same time using neural networks. Without applying nested Monte Carlo, the first method uses a series of neural networks to simultaneously compute both the lower and upper bounds of...

The severity and occurrence of rare events in financial markets has had a fundamental impact on the pricing and risk management of financial derivatives, such as volatility smile curves. However rare event modelling poses a problem in efficient and accurate simulation due to fundamental issues...

This paper proposes a simple algorithm extending the discrete CRR (1979) model to evaluate vulnerable derivatives, which include two stochastic processes, the underlying stock price and the assets value of the option writer. Introducing the concept of expected intrinsic value, univariate...

Derivatives have become widely accepted as tools for hedging and risk-management, as well as speculation to some extent. A more recent trend has been gaining ground, namely, arbitrage in derivatives. The critical parameter in derivatives pricing is the volatility of the underlying asset....

In this paper, we propose an easy-to-use yet comprehensive model for a system of cointegrated commodity prices. While retaining the exponential affine structure of previous approaches, our model allows for an arbitrary number of cointegration relationships. We show that the cointegration...

This paper investigates whether the overpricing of out-of-the money single stock calls can be explained by Tversky and Kahneman's (1992) cumulative prospect theory (CPT). We argue that these options are overpriced because investors' overweight small probability events and overpay for such...

Examination of the profile of the volume of call options traded and the prices at which they trade reveals a non-symmetric relationship which has implications concerning the empirical pricing of these contracts
