This paper describes the results of a twofold study that compared the performance of Initial Public Offering (IPOs) in the Brazilian stock market with that of incorporated company in 2004 and 2005 and also checked if these IPOs were included in the Bovespa Index (IBOV) in this period. We first collected data on stock price variations every year subsequent to the public offering. Thereafter, we compared the IPOs’ rates with those of the public corporations. The results show that 81.25% of the IPOs had positive returns in the first and the second years of anniversary, and only 50% of them had positive return in the third year. The youngest companies had the highest returns, and 45% of them were included in the IBOV in the period under scrutiny. The comparison of the ratios showed that IPOs of any age are more valued than the comparison companies. As a conclusion, we can say that the IPOs’ performance was significantly better than that of the comparison companies in the period studied.
