Markowitz model

Harry Markowitz introduced the mean-variance optimization model in 1952

The Markowitz model, introduced by Harry Markowitz in 1952, revolutionized portfolio management by focusing on optimizing portfolios based on expected returns and risk (variance). It allows investors to select securities that do not move perfectly together, thereby reducing overall portfolio risk. This model is foundational to Modern portfolio theory and remains a cornerstone in financial economics.

Example

Suppose an investor wants to minimize risk while achieving a specific return. Using the Markowitz model, they can analyze various portfolios consisting of different securities. By choosing securities that have low correlation, the investor can construct a portfolio with minimized variance for the desired return.

Remember this

Understanding the Markowitz mean-variance optimization is crucial for investors aiming to balance risk and return effectively in their investment portfolios.
