This paper describes the advantages of using a particular model of the relationships among securities for practical applications of the Markowitz portfolio analysis technique. A computer program has been developed to take full advantage of the model: 2,000 securities can be analyzed at an extremely low cost--as little as 2% of that associated with standard quadratic programming codes. Moreover, preliminary evidence suggests that the relatively few parameters used by the model can lead to very… Expand

Mathematical Analysis of Portfolio Selection: Principles and Application
THIS PAPER describes the workings of the Markowitz portfolio selection technique. It indicates how it can help the financial analyst and discusses the limitation of the method. Nearly 15 years haveExpand
Problems in the application of portfolio selection models
This paper discusses a number of problems which arise in the implementation of portfolio selection models. It is suggested that the effect of errors and biases in expected return forecasts can beExpand
A Linear Programming Algorithm for Mutual Fund Portfolio Selection
The portfolio selection problem faced by a mutual fund manager can be formulated following the Markowitz approach: find those portfolios that are efficient in terms of predicted expected return andExpand
A simulation model for evaluating the effectiveness of various stock market strategies
This paper develops a simulation model which can be used to investigate a wide variety of stock market invest ment strategies. A brief review of the literature of stock market forecasting is given.Expand
A Simple Algorithm for Optimal Portfolio Selection with Fixed Transaction Costs
The general optimal portfolio selection problem with fixed transaction costs is a complex mathematical programming problem. However, by placing reasonable restrictions on the variance-covarianceExpand
A Decision Theory Approach to Portfolio Selection
This paper starts with a brief summary of Harry Markowitz's portfolio selection model and proceeds to reformulate it within the framework of modern statistical decision theory. The future returnsExpand
Theory of portfolios: New considerations on classic models and the Capital Market Line
The aim of this paper is to present an alternative method to obtain the efficient portfolio in Roy's model starting from the concepts of critical return and risk which are introduced here. ThisExpand
Portfolio analysis with a large universe of assets
Covariance matrix optimization algorithms are applied to a large number of assets. A previous paper by Burgess and Bey (1988) suggests that attempting to optimize a large number of securities withExpand
Combining Portfolio Models
It is argued that it is unlikely to find an individual model which continuously outperforms its competitors and rather one should consider a combined model out of a given set of asset allocation models. Expand
A simulation model for evaluating the effectiveness of various stock market strategies
A simulation model which can be used to investigate a wide variety of stock market investment strategies and forecasting devices is developed and a few preliminary results are given. Expand
