This website is devoted to information on the Black-Litterman model. The Black-Litterman model for estimating asset returns is widely used in industry and has been widely studied in the academic and professional literature. Developed by Fischer Black and Robert Litterman in the early 1990's at Goldman Sachs, this model is used to estimate asset equilibrium returns and then to combine these returns with user views to derive updated estimates. These estimates can then be fed into a portfolio optimization tool to compute an efficient frontier.
