The IPO initial returns-aftermarket risk question revisited: evidence from firms in Taiwan

Using quarterly data from 2010 to 2019, this paper investigates the impact of listing status on the performance of the National Commercial Bank (NCB), the largest commercial bank in Saudi Arabia, by applying a combination of financial ratios analysis and efficient frontier analysis with a mix of parametric and non-parametric tests. The overall results show that although the NCB performance is superior compared to their counterparts, this superiority has deteriorated after the bank was listed in 2014. This result was captured by the deterioration in the efficiency measures of NCB, indicating the significance of using the efficient frontier analysis as an additional monitoring tool by the Saudi regulators. The financial ratios analysis also shows that even though the NCB profitability has increased, there is an increase in the bank’s overall risk after being listed. Therefore, Saudi regulators should closely monitor their listed banks as these banks are directed toward high-risk assets.

The Covid-19 pandemic has accelerated some structural changes in the healthcare industry, and several health-tech start-ups thrived by providing innovative solutions to the challenges imposed by the pandemic. To finance their growth, many of these companies went through mergers with Special Purpose Acquisition Companies (SPACs). The paper investigates the market performance of healthcare-focused US-listed SPACs. The study aims to analyze the returns that healthcare SPACs offer to their investors and ascertain the determinants that drive these returns over a sample of 33 SPACs that merged with a healthcare firm between 2018 and 2021. Linear regression is employed to identify the drivers of SPACs’ market performance. Portfolio analysis is also performed and compared against the Russell 2000 and the S&P500 Healthcare Indexes.
The first outcome accomplished by the analysis is that a portfolio made of healthcare-SPACs underperforms small-cap firms by 2.14% and the healthcare industry by 6.72% over a two-year period, even if the difference in the returns of the healthcare SPACs portfolio and the two benchmarks is not statistically significant. Moreover, a high level of redemptions, the presence of serial SPAC sponsors, cross-border deals, private equity and venture capital funds as sellers, and a high percentage of boutique investment banks among the sell-side advisors seem to negatively affect the returns of healthcare-focused SPACs with a significance level of at least 10%. Instead, a larger number of buy-side advisors appears to be beneficial for healthcare-focused SPACs’ market performance.

The capital market has increasingly become a pivotal avenue for enterprises seeking additional capital for expansion or operational enhancements. In raising funds through an Initial Public Offering (IPO), the company must publish its risk disclosure in the prospectus. Therefore, this study aims to investigate the impact of risk disclosure on the initial return of Indonesian companies undergoing IPOs during the pandemic. Using data from 136 out of 164 companies that went public between 2020 and 2022, sourced from the Indonesian Stock Exchange and company websites, the study employs the ordinary least squares method to estimate the impact of risk disclosures on initial returns during the pandemic. The findings reveal that external and overall risk disclosures significantly influence IPO initial returns. Specifically, Indonesian investors were particularly attentive to external and overall risks when evaluating IPOs during the pandemic. This heightened concern suggests that comprehensive risk disclosure can affect investor behavior and financial outcomes for companies going public in uncertain times, highlighting the importance of transparency in risk communication to support investor decision-making and market stability.
