Análise dos métodos de formação de carteira de investimentos defendidos por Benjamin Graham e Harry Markowitz

Abstract

The search for variable income investments has expanded in Brazil, as investors have been looking for options that bring greater profitability as the economy's base interest rate has fallen in the last half of the 2010s, which, as a result, leads to a drop in fixed income profitability. Therefore, this work initially considered the investment theory of currents of economic thought, in order to understand how investments work in general. After that, the methodologies of Benjamin Graham and Harry Markowitz were evaluated, so that the theory of the former defined which stocks would compose the portfolio and later redistribute the asset percentages to perform the optimization of the Markowitz portfolio. The results revealed that the main hypothesis, that the applicability of the theories studied in the formation of Ibovespa's asset portfolio makes investments more efficient, aiming at greater profitability and less risk, still resulting in different investment portfolios that can suit the investor's objective, as higher average return, lower or higher risk.
