Indicadores financeiros da bolsa de valores brasileira: utilização de um dashboard para análise e tomada de decisões

Abstract

This study aims to develop an interactive dashboard for analyzing financial indicators of companies listed on the Brazilian Stock Exchange (B3), with the goal of assisting novice investors in interpreting such information. The increasing complexity of financial data and the difficulty of understanding it without accounting or financial background motivated the creation of a visual and accessible tool based on Business Intelligence (BI) technologies. The methodology involved data collection through the Yahoo Finance API, the selection of relevant fundamental indicators such as ROE, Net Margin, and P/E ratio, and the implementation of the dashboard using the Python library Streamlit, chosen for its flexibility and ease of use. The dashboard enables clear and dynamic visualization of financial data, enhancing users’ understanding of company performance and supporting investment decisionmaking. The results demonstrate that the tool is effective in presenting accurate and accessible information, contributing to the democratization of financial analysis and reinforcing the role of information technology in the digital transformation of the capital market.
