Análise da relação entre indicadores financeiros e cotações das ações de empresas presentes na bolsa de valores

Abstract

Stock market investors who use the fundamental analysis look for criteria and indicators to identify what they consider the potential value of a stock and support the decision to buy or sell stocks. This research aims to investigate, through the calculation and analysis of correlation and determination coefficients, whether there is a relevant relationship between certain financial indicators and the stock prices of companies present on the stock exchange, as well as to identify and compare the values obtained between the different indicators and companies. The research has an exploratory, quantitative nature and used secondary data consisting of financial informations and stock prices from 8 companies between 2012 and 2020; the indicators were calculated based on the financial informations, while the correlation and determination coefficients were calculated based on the indicators and stock prices. The results showed that there is a significant relationship between most indicators and stock prices and that among companies most correlations were strong or moderate, although there were large differences in the results. Given the important relationship identified between the variables, it can be concluded that financial indicators can be very useful for the decision process of investing in stocks.
