We consider a multi asset financial market with stochastic volatility modeled by a Wishart process. This is an extension of the one-dimensional Heston model. Within this framework we study the problem of maximizing the expected utility of terminal wealth for power and logarithmic utility. We apply the usual stochastic control approach and obtain, explicitly, the optimal portfolio strategy and the value function in some parameter settings. In particular, we do this when the drift of the assets is a linear function of the volatility matrix. In this case the affine structure of the model can be exploited. In some cases we obtain a Feynman-Kac representation of the candidate value function. Though the approach we use is quite standard, the hard part is to identify when the solution of the Hamilton-Jacobi-Bellman equation is finite. This involves a couple of matrix analytic arguments. In a numerical study we discuss the influence of the investors' risk aversion on the hedging demand.

We maximize the expected utility from terminal wealth for a Constant Relative Risk Aversion (CRRA) investor when the market price of risk is an unobservable random variable and explore the effects of learning by comparing the optimal portfolio under partial observation with the corresponding myopic policy. In particular, we show that, for a market price of risk constant in sign, the ratio between the portfolio under partial observation and its myopic counterpart increases with respect to risk tolerance. As a consequence, the absolute value of the partial observation case is larger (smaller) than the myopic one if the investor is more (less) risk tolerant than the logarithmic investor. Moreover, our explicit computations enable to study in detail the so called hedging demand induced by parameter uncertainty.

This paper analyses the intertemporal hedging demand for stocks and bonds in South Africa, the United Kingdom and the United States. The analysis is done using an approximate solution method for the optimal consumption and wealth portfolio problem of an infinitely long-lived investor. Investors are assumed to have Epstein-Zin-Weil-type preferences and face asset returns described by a first-order vector autoregression in returns and state variables. The results show that the mean intertemporal hedging demands for stocks are considerably smaller in SA than in the UK or the US, whilst the mean intertemporal hedging demand for bonds are not significantly different from zero in any of the countries considered. Furthermore, it is found that stocks in the US and the UK do not present a useful hedging opportunity for an investor in SA, nor do SA stocks present a useful hedging opportunity for investors from the UK or the US.

AbstractThis paper studies the optimal consumption and portfolio problem of an investor with recursive preferences who is subject to time-varying margin requirements. The level of the requirements at each moment is determined by contemporaneous volatility of returns, which is stochastic and may have jumps. I show that the nonstandard hedging demand produced by margin requirements increases with their persistence and volatility. However, for realistic values of parameters, the hedging demand is small even in the presence of jumps, and contemporaneous jumps in prices have a much stronger effect on optimal portfolio than jumps in constraints.

AbstractWe study an investor’s asset allocation problem with a recursive utility and with tradable volatility that follows a 2-factor stochastic volatility model. Consistent with previous findings under the additive utility, we show that the investor can benefit substantially from volatility trading due to hedging demand. Unlike existing studies, we find that the impact of elasticity of intertemporal substitution (EIS) on investment decisions is of 1st-order importance. Moreover, the investor can incur significant economic losses due to model and/or parameter misspecifications where the EIS better captures the investor’s attitude toward risk than the risk aversion parameter.

Purpose – In this study, the author aims to examine the behavior of QQQ options at the time of the QQQ move from AMEX to NASDAQ on December 1, 2004. The author addresses the questions: is there a relation between hedging and speculation, if such a relation exists considering the improvement in market trading efficiency after the QQQ move did the relation between speculative demand for options and hedging demand for options strengthen at the time of the QQQ move, if such a relation exists does hedging activity follow speculative activity. Design/methodology/approach – The author uses the fact that deep-out-of-the-money puts are used for hedging, whereas deep-out-of-the-money calls are used for speculation. The author uses spectral analysis on QQQ options in the attempt to answer the research question. The author uses spectral analysis because the data in the study are non-normally distributed which would make parametric testing meaningless. Findings – The author finds that indeed the relation between speculative demand and hedging demand for options exists and strengthens after the consolidation of trading on NASDAQ and that hedging follows speculation. The fact that this relation exists is economically meaningful in that this is established for the first time empirically in support of the theoretical models predicting this relation's existence. Originality/value – Market participants on both the speculation side of the investment spectrum, such as hedge funds, and hedging side of the investment spectrum, such as mutual funds and money managers, would be interested in this topic and the findings of this paper. The main contribution of this study is in examining the relation between differential demand for options by using the non-parametric tools of spectral analysis. This helps extend the understanding of exchange traded funds' (ETF') option behavior and contributes to this strand of the ETF literature.
