Alternative Hedging in a Discrete-Time Incomplete Market
We present an alternative approach to hedging in incomplete markets. A corresponding alternative risk-minimization algorithm that identifies an optimal hedging portfolio consistent with initial capital and an investor-chosen risk criterion is developed. Having been introduced in earlier works by Josephy et al, it is adapted here to facilitate a comparison with both quadratic and piece wise linear local risk-minimization approaches reported in the work of Coleman et al. Numerical results establish that the alternative approach is competitive and frequently better than the local risk-minimization approaches. Various quantitative and qualitative comparisons are made between the local risk-minimization approaches and our alternative hedging approach.
期刊介绍:
This international peer-reviewed journal publishes a broad range of original research papers which aim to further develop understanding of financial risk management. As the only publication devoted exclusively to theoretical and empirical studies in financial risk management, The Journal of Risk promotes far-reaching research on the latest innovations in this field, with particular focus on the measurement, management and analysis of financial risk. The Journal of Risk is particularly interested in papers on the following topics: Risk management regulations and their implications, Risk capital allocation and risk budgeting, Efficient evaluation of risk measures under increasingly complex and realistic model assumptions, Impact of risk measurement on portfolio allocation, Theoretical development of alternative risk measures, Hedging (linear and non-linear) under alternative risk measures, Financial market model risk, Estimation of volatility and unanticipated jumps, Capital allocation.
