Gerenciamento de portfólio de investimento no mercado acionário brasileiro: alavancando retornos e mitigando riscos

Abstract

In recent years, investment in financial assets has experienced notable growth in Brazil. This phenomenon can largely be attributed to the increasing popularization of the subject due to finance content creators on the internet and the democratization of investment means. This movement reflects a paradigm shift regarding traditional savings, as more people recognize the importance of making better financial choices. The increasing participation of investors and the broadening access to various financial products represent a positive development in the Brazilian economy. However, this advancement also brings a relevant concern: the increased exposure of often inexperienced investors to higher-risk financial assets, such as stocks. Therefore, the aim of this research is to propose a methodology for managing investment portfolios in the Brazilian stock market. To achieve this, a literature review was conducted on mathematical optimization techniques that seek to improve asset allocation, maximizing the relationship between return and financial risk. The review was based on the concepts of Modern Portfolio Theory by Markowitz and the Capital Asset Pricing Model (CAPM). In order to enhance the obtained results, a quantitative study focused on diversification and correlation between assets was carried out. To evaluate the performance of the assembled portfolios, comparisons were made with the main market indices.
