Indicadores de John Bollinger: operações em ativos do mercado de ações da B3.

Abstract

In 2001, John Bollinger, the professor and financial analyst published a book entitled Bollinger on Bollinger Bands, which aimed to use statistical measures such as mean and standard deviation to analyze stocks in the financial market. This research described how investors can use the technical analysis indicators developed by John Bollinger to support share buy and sell decisions in the stock market. It was important to consider the theoretical revision on technical analysis, providing the best interpretation of graphs and reading of price trends to reach the goal that was settled. Simulations on B3 stock charts were conducted through Tradingview.com, using Bollinger indicators: Bollinger bands; price indicator (% b); and the bandwidth indicator (BBW). The simulations were applied in the shares of Banco do Brasil (BBAS3), Banco Itaú (ITUB4) and Banco Banrisul (BRSR3), in a trading period with intervals that mark important movements of the chart in approximately one year. Overall, the simulated operations with the indicators presented provided the best opportunities to buy and sell the shares, reaching approximately percentages of 100% annual profitability, based on compound interest in the shares analyzed.
