The aim of this study is to show the behavior of investment portfolios designed for six individual investors with low, moderate and high risk profiles. The work was developed due to the increased interest of Brazilians in making investments, the growing dissemination of investment options by financial institutions and the greater ease with which ordinary investors can make and manage their own investments. The aim was to help this type of investor to make investments based on the tools available on the market, analyzing the best assets to invest in, generating an expected profit in relation to their degree of propensity to risk without the need for a specialized company. The study included the selection of assets on the market and their 12-month returns. The proposed objective was achieved by carrying out a projection, in which information was collected on the investor's income and their propensity to risk, and based on the data obtained, an investment portfolio was set up for each investor and their returns calculated over five different return periods.
