Abstract

This study aimed to evaluate the performance of four mining companies listed on the Brazilian stock exchange (B3), identified by the codes AURA33, CBAV3, CMIN3, and VALE3, over the years 2021, 2022, 2023, and 2024. The analysis was conducted based on the fundamental analysis methodology, considering economic and financial indicators related to liquidity, indebtedness, profitability, and market valuation. The research involved the collection, organization, analysis, and comparison of economic and financial data from these companies, with the objective of presenting information in a clear and objective manner. Based on this analysis, it was possible to identify which indicators reflected the best performance throughout the analyzed period, providing a comprehensive view of each company's strengths and weaknesses. From the results obtained, a scoring system was developed in which the companies' performances were classified according to their results in each indicator. The sum of this evaluation indicated CMIN3 as the company with the best overall performance. Furthermore, the study highlighted the existing competitiveness among these companies in the market, demonstrating each one's value generation capacity within the Brazilian mining sector.
