Abstract

The present study focused on the investigation of the stock market and its main objective was to evaluate the return on investment using the moving averages indicator. Was used an exploratory study of a quantitative nature, with a documental basis. The data collection used secondary data from B3, through the survey of the price variation of a group of shares, from January to December 2016. The research universe was composed of companies that make up the theoretical portfolio of the Bovespa Index - IBOV and which had a participation of more than 1% in the valid portfolio for the four-month period from January to April 2017, totaling 26 shares corresponding to 81.829% of the IBOV's weight. The analysis of the data was done by checking the arithmetic and exponential averages, whenever the Exponential Moving Average (MME9) crossed over the Arithmetic Moving Average (MMA21), a purchase was made, in the same way that the MME9 crossed to under MMA21 a sale was made, calculating gain or loss in the transaction. The results showed assets with higher gains (PETR4 and VALE5) and others with lower results (EMBR3 and ABEV3). After analyzing the selected assets, it was concluded that the MMA21 and MME9 are effective and efficient in the positive result, becoming a very efficient setup in the maximization of results, when the stock market is in a clear upward trend, as occurred in the year 2016.
