We propose a new portfolio optimization method combining the merits of the shrinkage estimation (Jorion, 1985, 1986 and 1991), vine-copula structure (Aas and Berg, 2009), and Black-Litterman model (Black and Litterman, 1991 and 1992). It is useful for many investors to satisfy simultaneously the three investment objectives, estimation sensitivity, asymmetric risks appreciation and portfolio stability. A typical investor with such objectives is a sovereign wealth fund (SWF). We use China’s SWF as an example to empirically test the method based on a 15-asset strategic asset allocation problem. Robustness tests using sub-samples not only show the method's overall effectiveness, but also manifest that the function of each component is as expected.
