Böcker av Harry M. Markowitz

The man who created investing as we know it provides critical insights, knowledge, and tools for generating steady profits in today's economy.When Harry Markowitz introduced the concept of examining and purchasing a range of diverse stocks-in essence, the practice of creating a portfolio-he transformed the world of investing. The idea was novel, even radical, when he presented it in 1952 for his dissertation. Today, it's second-nature to the majority of investors worldwide. Now, the legendary economist returns with the third volume of his groundbreaking four-volume Risk-Return Analysis series, where he corrects common misperceptions about Modern Portfolio Theory (MPT) and provides critical insight into the practice of MPT over the last 60 years. He guides you through process of making rational decisions in the face of uncertainty-making this a critical guide to investing in today's economy. From the Laffer Curve to RDM Reasoning to Finite Ordinal Arithmetic to the ideas and concepts of some of history's most influential thinkers, Markowitz provides a wealth and depth of financial knowledge, wisdom, and insights you would be hard pressed to find elsewhere. This deep dive into the theories and practices of the investing legend is what you need to master strategic portfolio management designed to generate profits in good times and bad.

In 1952, Harry Markowitz published "Portfolio Selection," a paper which revolutionized modern investment theory and practice. The paper proposed that, in selecting investments, the investor should consider both expected return and variability of return on the portfolio as a whole. Portfolios that minimized variance for a given expected return were demonstrated to be the most efficient. Markowitz formulated the full solution of the general mean-variance efficient set problem in 1956 and presented it in the appendix to his 1959 book, Portfolio Selection. Though certain special cases of the general model have become widely known, both in academia and among managers of large institutional portfolios, the characteristics of the general solution were not presented in finance books for students at any level. And although the results of the general solution are used in a few advanced portfolio optimization programs, the solution to the general problem should not be seen merely as a computing procedure. It is a body of propositions and formulas concerning the shapes and properties of mean-variance efficient sets with implications for financial theory and practice beyond those of widely known cases. The purpose of the present book, originally published in 1987, is to present a comprehensive and accessible account of the general mean-variance portfolio analysis, and to illustrate its usefulness in the practice of portfolio management and the theory of capital markets. The portfolio selection program in Part IV of the 1987 edition has been updated and contains exercises and solutions.
