[pt] O objetivo deste trabalho é verificar a ocorrência do underpricing no mercado brasileiro e analisar sua relação com fatores internos, externos da empresa e da oferta. O underpricing é considerado uma anomalia de mercado, pois proporciona para os investidores ganhos elevados com a mesma composição de risco. Para as empresas, a ocorrência do underpricing no IPO compromete a eficiência da oferta, uma vez que reduz o montante arrecadado. Este fenômeno foi estudado nas décadas de 80 e 90, porém somente na última década estudos começaram a ser realizados com foco no mercado brasileiro. Desta forma, foi observada a ocorrência do underpricing no mercado brasileiro em uma amostra composta por 30 IPO entre os anos de 2010 a 2016, e para analisar a relação dos fatores foi aplicado a análise de cluster aliada ao teste não paramétrico de Wilcoxon. / [en] The objective of this paper is to verify the occurrence of underpricing in the Brazilian market and to analyze its relationship with internal, external factors of the company and the offer. Underpricing is considered a market anomaly as it provides investors with high returns with the same risk composition. For companies, the occurrence of underpricing in the IPO compromises the efficiency of the offer, since it reduces the amount collected. This phenomenon was studied in the 80 s and 90 s, but only in the last decade studies began to be carried out focusing on the Brazilian market. Thus, underpricing in the Brazilian market was observed in a sample composed of 30 IPO between the years 2010 and 2016, and to analyze the relationship of factors was applied to the cluster analysis allied to the Wilcoxon nonparametric test.
