Abstract

Equity offerings are an option available to companies to raise capital. The aim of this paper is to study the occurrence of market anomalies in this context. Using a sample of more than 40,000 equity offerings from 25 countries, an event study has been conducted to estimate and explain abnormal returns around the announcement date. The results demonstrate the existence of significant abnormal returns, robust to different regulations. We also identify factors that appear to be related to its formation, such as being listed on a benchmark stock index or the liquidity of the company’s shares.
