Dataset on share issuance, abnormal returns and market timing in the Brazilian stock market

摘要

This article presents a dataset to investigate the determinants of firms’ decision for primary share issuance and the effects of market timing on primary share issues in the Brazilian stock market. The data refer to Brazilian nonfinancial firms that issued primary shares (IPOs and SEOs) in the 2004–2015 period. The data were gathered from the online bases of Economatica?and the S?o Paulo Securities, Commodities and Futures Exchange (BM&FBovespa). The final sample was composed of 123 firms and 165 primary share issues: 97 initial public offerings and 68 follow-on offerings. The dataset was developed to support a model that captures market timing behavior through cumulative abnormal returns and shows the effects of this behavior on the amount of proceeds raised. The dataset contains subsamples and different analysis time windows, processed and unprocessed data. Researchers can use the dataset for future research and comparisons with other markets and models. The related research article using part of the current dataset was published under the following title: “Effects of market timing on primary share issues in the Brazilian capital market” (Gomes et?al., 2019).
