This paper examines IPOs anomalies from hot-issue perspective. As IPOs may hold various hot-issue characteristics, we inspect the joint effects of hot-issue on firm performance to unravel whether the issuers manipulate IPOs timing. We find that the initial returns of IPOs made on hot market conditions significantly outperform those of non-hot market IPOs. The results appear to be more distinguished when the IPO firms possess different hot-issue characteristics. It is noteworthy that the long-term performances of hot-issue IPOs decline constantly and are worse than non-hot issuers, no matter how we define hot issue. Last, we find that IPOs with combined hot-issue characteristics has significantly lower allotment rate than others.
