Resumo

Financial markets are complex systems, which can be studied under the lens of econophysics, including the study of phenomena such as power laws. We test the hypothesis of a power law in Ibovespa, the main Brazilian stock market index, and cannot dismiss the hypothesis that its stocks are distributed following a power law. This is most interesting, as these stocks are ordered by individual trading volumes, thus a similar pattern always emerges organically even though companies are always exchanging positions and being excluded or added to the index.
