Introdução à Econofísica

The present paper proposes to use some of the hypothesis of the Dow Theory and the physical model called Random Walk, introduced from the binomial probability studied in high school, to evaluate the behavior of the IBOVESPA and some stocks that had a strong influence on the composition of this index in 2018. It was proposed an interdisciplinary activity using the concepts of Physics, mathematics and economics and the use of spreadsheet to perform the calculations. It was observed that students, although they had already studied the subjects separately in the Physics and Mathematics subjects, had not noticed the connections between the subjects and the application in economics allowed them to better understand the news related to the financial market widely divulged in the news.
