Consider an agent who holds a stock, but is allowed to buy and hold some quantity of at-the-money put options on the stock. Such an agent must decide the optimal use of financial derivatives under trade restrictions. This paper uses simulation to compare the optimal quantity when the agent...

Conditional Value-at-Risk (CVaR) measures the expected loss amount beyond VaR. It has vast advantage over VaR because of its property of coherence. This paper gives an analytical solution in a complete market setting to the risk reward problem faced by a portfolio manager whose portfolio needs...

Empirical evidence suggests that asset returns correlate more strongly in bear markets than conventional correlation estimates imply. We propose a method for determining complete tail-correlation matrices based on Value-at-Risk (VaR) estimates. We demonstrate how to obtain more efficient...

Most socially responsible investment funds combine a sustainability objective with a tracking error constraint. We characterize the impact of a sustainability constraint on the mean-tracking error efficient frontier and illustrate this on a universe of US stocks for the period 2003–2010.

We prove a formula for the computation of optimal financial investments in an expected utility framework with arbitrary (not necessarily concave) utility functions. This extends classical results on optimal financial investments for strictly concave utility functions and is of importance...

Increasingly Islamic financial institutions are being pressured by critics to offer profit and loss sharing (PLS) financing for the purpose of entrepreneurial development. We believe the growth of PLS can be incentivized by increasing the participation of Islamic asset managers and mutual funds...

Islamic equity portfolios work with a smaller investment universe given the filtering of non-Shari’ah compliant stocks. It has been theoretically argued that this culminates in suboptimal portfolio diversification which in turn adversely affects risk-adjusted returns. We employ a number of...

The paper is the first attempt to evaluate the role of gold as a hedge (negative or low correlation with equities in normal market conditions) and safe haven (negative or low correlation in times of market turbulence) by using the daily data for gold and Shariah-compliant equities ranging from...

This paper investigates the volatility and correlations of stock returns of some crisis-hit countries such as, US, Greece, Thailand and Malaysia during the major global financial crises since 1992. The paper makes an attempt to address the following two issues: Firstly, to measure the extent of...

The purpose of this paper is to analyze the possible portfolio diversification opportunities between Asian Islamic Market and other regions‟ Islamic Markets; namely USA, Europe and BRIC. This study makes the initial attempt to fill in the gaps of previous studies by focusing on the proxies of...
