Author’s methods provides a comparison between the actual implementations of Black-Litterman used by the various authors.

Black–Litterman model – Wikipedia

For a more thorough discussion see my paper on the Black-Litterman model. In financethe Black—Litterman model is a mathematical model for portfolio allocation developed in at Goldman Sachs by Fischer Black and Robert Littermanand published blacklittermwn In principle Modern Portfolio Theory the mean-variance approach of Markowitz offers a solution to this problem once the expected returns and covariances of the assets are known.

This table is not meant to be complete, but to be a summary of important papers on the model. The blacklifterman methods section has been updated with a new taxonomy of the model, and many papers have been added. Home What is blacklitterman. Asset allocation is the decision faced by an investor who must choose how to allocate their portfolio across a few say six to twenty asset classes.

An implementation of the Black-Litterman model in python and the worked example from the He and Litterman paper Updated Jun 22 Michaud et al No Yes Provides arguments against using hybird and alternative variants of the 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. In general, when there are portfolio constraints – for example, when short sales are not allowed – blacklittefman 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.

If you just want to get liyterman the details and write some code, this is the quickest way.

This page was last edited on 16 Februaryat Views Read Edit View history. The Global Equilibrium examples pull together some simple examples from the Global Equilibrium chapter of Litterman’s book. Information on general topics in financial informatics can be found at financialinformatics. The user is only required to state how his assumptions about expected returns differ from the markets and wwe state his degree of confidence in the alternative assumptions.

The long term goal is to duplicate the model used by Black and Litterman in their initial paper. Drobetz Yes Yes One of the first papers on the canonical form not by an original author of the model.

Additional Resources Resources have now been moved into littermna pages for paperslitteman and implementations in order to keep the front page a bit more clean.

New paper focusing on Tau littterman if you really need it Updated 1 November New paper focusing on Tau and if you really need it Updated 1 November 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. 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 littermna to take into account the ‘views’ i.

An excel spreadsheet showing the example worked in the He and Litterman paper Updated Jun 26 The information is organized historically and by expression of the model.

A new implementation of the Black-Litterman model in Excel is available on the implementations page. A new spreadsheet which illustrates the differences between the reference models.

It seeks to overcome problems that institutional investors have encountered in applying modern portfolio theory in practice. 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.

From this, the Black—Litterman method computes the desired mean-variance efficient asset allocation.
