International diversification versus domestic diversification : mean-variance portfolio optimization and stochastic dominance approaches

Abid, Fathi; Leung, Pui-lam; Mroua, Mourad; Wong, Wing Keung - In: Journal of risk and financial management : JRFM 7 (2014) 2, pp. 45-66

This paper applies the mean-variance portfolio optimization (PO) approach and the stochastic dominance (SD) test to examine preferences for international diversification versus domestic diversification from American investors’ viewpoints. Our PO results imply that the domestic diversification...

Fung, Eric S.; Lam, Kin; Siu, Tak Kuen; Wong, Wing Keung - In: Journal of risk and financial management : JRFM 4 (2012) 1, pp. 43-73

Recently, there has been a considerable interest in the Bayesian approach for explaining investors' behaviorial biases by incorporating conservative and representative heuristics when making financial decisions, (see, for example, Barberis, Shleifer and Vishny (1998)). To establish a...

Ly, Sel; Pho, Kim-Hung; Ly, Sal; Wong, Wing Keung - In: Journal of risk and financial management : JRFM 12 (2019) 1/42, pp. 1-27

applications in Risk Management, Finance, Economics, Science, and many other areas. This paper develops the theory on both density … . Thereafter, we extend the theory by establishing the density and distribution functions for the quotients Y=X1X2 and Z=X1X1+X2 of … two dependent normal random variables X1 and X2 in the case of Gaussian copulas. We then develop the theory on the median …
