The Further Theoretically Derivation and Empirical Analysis of the Black-Litterman Portfolio Model
Abstract:This paper deduced the function of optimal weight and confidence levels, and then simplified this formula under the assumptions that all the assets to be invested are uncorrelated, and the investor has only one absolute view. Based on this, this paper also analysed the formula of the confidence levels and optimal weight. Finally, this paper figured out how the investor would establish his portfolio and how much his profit would be (including the insider-trading case), according to his view, and the confidence level of this view. The ‘Fat finger’ trading error, caused by Everbright Securities Company Limited on August 16, 2013, was taken as an example to analyse.
