Portfolio optimization - a practical approach Andrzej Palczewski Institute of Applied Mathematics Warsaw University June 29‚ 2008 1 Introduction The construction of the best combination of investment instruments (investment portfolio) is a principal goal of investment policy. This is an optimization problem: select the best portfolio from all admissible portfolios. To approach this problem we have to choose the selection criterion first. The seminal paper of Markowitz [8] opened a new era

Optimal Versus Naive Diversification: How Inefficient is the 1/N Portfolio Strategy? Victor DeMiguel London Business School Lorenzo Garlappi University of Texas at Austin Raman Uppal London Business School and CEPR Downloaded from http://rfs.oxfordjournals.org/ at BCV - Research Department on October 26‚ 2011 We evaluate the out-of-sample performance of the sample-based mean-variance model‚ and its extensions designed to reduce estimation error‚ relative to the naive 1/N portfolio.

These matrices focus on internal strengths and weaknesses as well as external opportunities and threats. The rating for each matrix is based both on industry standards and company performance on each measure. These matrices aid comprehension and are very useful in presenting company strategic success.

3.1 Matrices Copyright © Cengage Learning. All rights reserved. Matrices Matrices are classified in terms of the numbers of rows and columns they have. Matrix M has three rows and four columns‚ so we say this is a 3 4 (read “three by four”) matrix. 2 Matrices The matrix has m rows and n columns‚ so it is an m n matrix. When we designate A as an m n matrix‚ we are indicating the size of the matrix. 3 Matrices Two matrices are said to have the same order (be the

multiplication used is ordinary matrix multiplication. If this is the case‚ then the matrix B is uniquely determined by A and is called the inverse of A‚ denoted by A −1 . It follows from the theory of matrices that if for finite square matrices A and B‚ then also [1] Non-square matrices (m-by-n matrices for which m ≠ n) do not have an inverse. However‚ in some cases such a matrix may have a left inverse or right inverse. If A is m-by-n and the rank of A is equal to n‚ then A has a left inverse:

In mathematics‚ a matrix (plural matrices) is a rectangular array of numbers‚ symbols‚ or expressions‚ arranged in rows and columns.[1][2] The individual items in a matrix are called its elements or entries. An example of a matrix with 2 rows and 3 columns is Matrices of the same size can be added or subtracted element by element. But the rule for matrix multiplication is that two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. A
