At the highest level we can separate the expression of the model used into Bayesian and non-Bayesian. For a more thorough discussion see my paper on the Black-Litterman model.

I’ve added the readling list as a list of papers which I am reading, or have recently found which are relevant to the Black-Litterman model, or to the topic of asset allocation.
Drobetz Yes Yes One of the first papers on the canonical form not by an original author of the model. If you just want to get to the details and write some code, this is the quickest way.

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. Resources have now been moved into seperate pages for paperstheses and implementations in order to keep the front page a bit lifterman clean.

Black–Litterman model – Wikipedia
New paper focusing on Tau and if you really need it Updated 1 November This site provides a source of information on the Black-Litterman Model for estimating returns and covariances for input to optimization models. 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.
The opinions expressed on this website are my own and not those of my employer. This table is not meant blaci be complete, but to be wwe summary of important papers on the model.
This list is not blacl, though I expect to continually add information to it as time is available. For example, a globally invested pension fund must choose how much to allocate to each major country or region.
For more details on the Black-Litterman Model, 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.
The long term goal is to duplicate the model used by Black and Litterman in their initial paper. Provides arguments against using hybird and alternative variants of the model. Allows for arbitrary distributions. Ignores modern econometrics and Bayesian statistics in the process.
It seeks to overcome problems that institutional investors have encountered in applying modern portfolio theory in practice.

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. While Modern Portfolio Theory is an important theoretical advance, its application has universally encountered a problem: The author’s methods section has been updated with a new taxonomy of the model, and many papers have been added.
