This paper studies the normality of two Portuguese stock exchange indexes, using daily returns for the period 1990-1995. The results of the tests allow discarding the hypothesis of normality. Weak form efficiency, evaluated through runs tests, is also rejected, while daily returns turn out to be positively skewed.
