“…Many IPO studies use underpricing (usually measured as the one-day CAR or simply as the return measured by the first day closing price to launching price) and other performance variables associated with the firm's valuation upon the IPO event. While we recognize the benefit of these popular metrics, we preferred to use one-year CAR due to five reasons: (1) Its previous usage in signaling and IPO literature (Bruton et al, 2010; Drebinger et al, 2019; Gao & Jain, 2011; Gibbs & Hao, 2018); (2) Underpricing fails to assess short-term performance (Park, Borah, & Kotha, 2016); (3) The signaling effect of PE funds tends to be durable and prominent over long periods of time (Arikan & Capron, 2010); (4) In several contexts, floating prices after the IPO event suffer several distortions, such as partial adjustment (Bradley & Jordan, 2002), in which underwriters proposedly establish an issuing price below the market value estimated during the book building process, in order to compensate institutional investors for disclosing information. Such distortions eventually fade out during the first year upon the IPO; (5) The investors in Brazil still need credible signs to assess the quality of the management after one-year of issuance.…”
