We examine whether hedging effectiveness is affected by asymmetry in the return distribution by applying tail specific metrics to compare the hedging effectiveness of short and long hedgers using crude oil futures contracts. The metrics used include Lower Partial Moments (LPM), Value at Risk (VaR) and Conditional Value at Risk (CVAR). Comparisons are applied to a number of hedging strategies in...

For evaluating a hedging strategy we h a ve t o k n o w a t e v ery instant the solution of the Cauchy problem for a parabolic equation (the value of the hedging portfolio) and its derivatives (the deltas). We suggest to nd these magnitudes by Monte Carlo simulation of the corresponding system of stochastic diierential equations using weak solution schemes. It turns out that with one and the sa...

In this article the problem of inventory management of a single-stage singleproduct and two-machine-state continuous-flow manufacturing system with constant demand is considered. The machine is subject to operation-dependent failures. All the random variables are exponentially distributed. The goal is to obtain, in this case, the optimal policy which minimizes the discounted cost function. It i...

This paper investigates corporate hedging activities in the Australian gold mining industry. We find that the Australian companies in 1997 are more actively involved in gold derivative markets than their counterparts in North America in 1993. This may suggest a general risk-averse attitude among the Australian managers when comparing with the North American managers. We also find that corporate...

This paper considers the multiperiod hedging decision in a framework of mean-reverting spot prices and unbiased futures markets. The task is to determine the optimal hedging path, i.e., the sequence of positions in futures contracts with the objective of minimizing the variance of an uncertain future cash flow. The model is used to illustrate both hedging using a matchedmaturity futures contrac...

A reservoir operation model of Mun Bon and Lam Chae reservoirs was developed to simulate reservoir operation using a hedging policy. A variety of common hedging forms was specified, including one-point hedging, two-point hedging and zone-based hedging. The simulated results were compared with the standard operating policy and probability based rule curve. The percentage of failure frequency, av...

Basis = price of hedged asset-price of hedging instrument problem of basis risk: uncertainties of processes describing the evolution of prices of asset and hedging instrument not identical, only highly correlated Example 1: weather derivatives hedged asset: heating oil sales, hedging instrument: HDD derivative HDD derivative: contract paying a premium in case HDD above a critical threshold Exam...

ABSTRACT In this paper, under constraint of delta-strategy and by importing another related risky asset to compose a hedging portfolio comprising the underlying asset and riskless asset(the Bond). Firstly, we excellently devise a dynamic hedging program for contingent claims; and then, according to Principle of Dynamic Programming and by taking advantage of backward recursion technique, at each...

This paper investigated the hedging effectiveness of crude palm oil futures market in Malaysia from January 2009 to June 2011 which traded under Bursa Malaysia Derivatives Berhad. Ordinary Least Squared (OLS) method was used to compute Minimum-Variance hedging ratio (MVHR), R-squared and hedging effectiveness by using daily data from settlement price of crude palm oil futures contracts and spot...

This paper mainly discusses the American option’s hedging strategies via binomial model and the basic idea of pricing and hedging American option. Although the essential scheme of hedging is almost the same as European option, small differences may arise when simulating the process for American option holder has more rights, spelling that the option can be exercised at anytime before its maturi...
