We present a new model of normal tempered stable (NTS) processes with stochastic correlation for multi-asset option pricing. The model is constructed by extending the constant correlation term in the NTS model to the stochastic correlation making use of the Ornstein-Uhlenbeck process. As the...

In this paper, we combine modern portfolio theory and option pricing theory so that a trader who takes a position in a European option contract and the underlying assets can construct an optimal portfolio such that at the moment of the contract's maturity the contract is perfectly hedged. We...

We analyze the effects of spot market short-sale constraints on derivatives trading using a unique Chinese stock market futures trading database. Due to short-sale constraints, investors' pessimistic views on the underlying index can be expressed solely through short futures positions, while...

We prove the existence of statistical arbitrage opportunities for jump-diffusion models of stock prices when the jump-size distribution is assumed to have finite moments. We show that to obtain statistical arbitrage, the risky asset holding must go to zero in time. Existence of statistical...
