Overview This site provides a source of information on the Black-Litterman Model for estimating returns and covariances for input to optimization models. At htgp highest level we can separate the expression of the model used into Bayesian and non-Bayesian. Black—Litterman overcame this problem by not requiring the user to input estimates of expected return; instead it assumes that the initial expected returns are whatever is required so that the equilibrium asset allocation is equal to what we observe in the markets.

Additional Resources Resources have now been moved into seperate litgerman for paperstheses and implementations in order to keep the front blacklittwrman a bit more clean. This list is not complete, though I expect to continually add information to it as time is available.

There is now also an excel spreadsheet with the He and Litterman example worked. For example, a globally invested pension fund must choose how much to allocate to each major country or region.

Replace reverse optimization and bayes formula with various optimization models. The model starts with the equilibrium assumption that the asset allocation of a representative agent should be proportional to the market values of the available assets, and then modifies that to take into account the ‘views’ i.

New paper focusing on Tau and if you really need it Updated 1 November For more blackljtterman on the Black-Litterman Wwq, you might find the discussion of Tau useful as it provides some background on the confusing parameter Tau and describes how it can be used, or not depending on how you use the model.

An implementation of the Black-Litterman model in python and the worked example from the He and Litterman paper Updated Jun 22 The Bayesian expression of the model is the canonical model presented by Black and Litterman, He and Litterman and Litterman et al, An implementation of the Black-Litterman model in python and the worked example from the He and Litterman paper Updated Jun 22 This website is provided “as is” without any representations or warranties, expres or implied. From this, the Black—Litterman method computes the desired mean-variance efficient asset allocation.

In general, when there are portfolio constraints – for example, when short sales are not allowed – the easiest way to find the optimal portfolio is to use the Black—Litterman model to generate the expected returns for the assets, and then use a mean-variance optimizer to solve the constrained optimization problem.
