The purpose of this work is to investigate the existence of short-term returnpredictability in the Brazilian stock market between 1995 and 2016. The relationship
between predictability and liquidity is also evaluated, in addition to exploring whether
predictability is influenced by economic crises and companies’ size. Using serial independence tests and regression analysis, results indicated that there is no predictability
in the Brazilian stock market, except for portfolios of smaller companies. However, findings suggested a non-random occurrence of subperiods in which predictability exists,
linked to the subprime crisis, but not to liquidity fluctuations nor domestic recessions.
