O uso da análise gráfica no mercado de ações: um estudo de caso da ação preferencial do Bradesco

Abstract

The main objective of this study is to evaluate the efficiency and effectiveness of stock market technical analysis methodology. Initially, we discussed the principles of technical analysis and fundamental analysis, verifying that, due to the use of computational methods, the technical analysis is more easily interpreted and used. In order to verify the performance of technical analysis in the stock market, the following indicators was applied to the graph of the preferred share price of Banco Bradesco: Moving Averages, MACD, Bollinger Bands, RSI and Stochastics. The indicators showed several purchase and sale assets points, and then the financial result was compared to the same period in Ibovespa. At the end of the study it was found that the use of such indicators maximizes the financial result in the stock market, because evidencing the right times do buy and sell maximizes profits and minimizes losses.
