Resumo:
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.
