Put-call parities and the value of early exercise for put options on a performance index

Article Abstract:

There is a correlation between the premium placed in an early exercise of a put option from deviations of the European put-call parity with both the volatility of the index and the interest rate. However, it is negatively correlated with the time to maturity. A previous study by Zivney in 1991 revealed deviations from the European put-call parity that are caused by early exercise. The recent findings could be used for developing pricing models for put options in the US.

Out-of-sample hedging effectiveness of currency futures for alternative models and hedging strategies

Article Abstract:

Hedging effectiveness of currency futures for hedging strategies in an out-of-sample setting only occurs in the minimum-variance model and the alpha-t model. The minimum-variance model reduces the variance of portfolio while the alpha-t model reduces the disutility of a loss. Among the three hedge types namely, naive hedge, model-based hedge and the long-term average model-based hedge, the naively hedged position is most effective with the use of the two models.
