Financing Decisions and Abnormal Returns: An Analysis of Brazilian Companies

In this paper, we developed an approach for the empirical testing of the relationship between the financing choices of companies and the abnormal returns obtained by their shareholders. We innovate by incorporating controls on how this relationship is affected by the capabilities of each funding source, at different levels of returns, through quantile regression. The estimation of the model for a sample of Brazilian companies indicates the inexistence of a significant relationship between abnormal returns and debt issuance. The same occurs between abnormal returns and equity issuance, with one exception: when there is a deficit of internal financing that extrapolates the available safe debt and the abnormal returns are, at least, median, this relationship becomes significant and positive. Considered as a whole, the results suggest an indifference to the sources of funds used by the company. Among the contributions, we highlight the incorporation of the aforementioned controls, which bridges the gap identified in the literature relating business financial flows and stock returns.
