  • Initial public offering (IPO) has been well known to be underpriced initially and under-performed in the long run. However, whether an IPO is underpriced or not strongly depends on how to measure the fair value. This paper hand collects data of IPOs newly listed in Korea market when whether IPO is overpriced or not is clearly distinguishable. The overpriced IPO refers to as the one the underwriters buy back after the listing. With the data, the paper examines that IPOs are overpriced and that the characteristics are related to the underpricing at the aftermarket dates and the performance in the long run. The data of clearly overpriced IPOs are little available from other IPO markets like US IPO market. From the data of IPOs listed under the underwriting rule of market stabilization, the results obtainable are the followings. First of all, the average initial return 70% of the underpriced IPO at the aftermarket dates is greater than the one 40% of the overpriced one. The overpriced IPOs are priced highly over the mid prices of the price bands at the pricing dates and then supported by relatively higher subscription rates of individual investors. The probit analyses moreover report that individual investors do not distinguish the overpricing of IPOs from the underpricing. These imply that the overpricing is strongly affected by the underwriting rule on the initial pricing.

  • This paper examines the effect of unique underwriter lockup on the initial returns of an initial public offering (IPO) in the Korean Securities Dealers Automated Quotation (KOSDAQ). Underwriter lockup induces underwriters to underprice IPOs and stabilize aftermarket prices. The inducement is explored with respects to the mixtures of distributions of the initial returns consistent with underpricing and stabilization. Whether the inducement is meaningful when other factors are controlled is also explored. These explorations provide evidence that underwriter lockup leads to more positive average initial returns in the three aftermarket months.

  • In this paper, we develop a new time series model for predicting IPO (initial public offering) data with non-negative integer value. The proposed model is based on integer-valued autoregressive (INAR) model with a Poisson thinning operator. Just as the heterogeneous autoregressive (HAR) model with daily, weekly and monthly averages in a form of cascade, the integer-valued heterogeneous autoregressive (INHAR) model is considered to reflect efficiently the long memory. The parameters of the INHAR model are estimated using the conditional least squares estimate and Yule-Walker estimate. Through simulations, bias and standard error are calculated to compare the performance of the estimates. Effects of model fitting to the Korea's IPO are evaluated using performance measures such as mean square error (MAE), root mean square error (RMSE), mean absolute percentage error (MAPE) etc. The results show that INHAR model provides better performance than traditional INAR model. The empirical analysis of the Korea's IPO indicates that our proposed model is efficient in forecasting monthly IPO volumes.

  • Purpose - This study aimed to examine the behavior surrounding the Initial Public Offering (IPO) event of firms within the same conglomerate and the impact of under-pricing and Return on Equity(ROE) on a firm's abnormal stock returns. Design/methodology - This study collected data from 166 South Korean Chaebols, consisting of 355 firms distributed as 202 listed on Korea Composite Stock Price Index (KOSPI) and 153 firms listed on Korean Securities Dealers Automated Quotations (KOSDAQ) from 2000 to 2020. The Capital Asset Pricing Model (CAPM) and the multiple regression analysis were hired to analyze the data. Findings - First, we found an adverse price reaction of IPO listing in the same chaebol group, and firms with higher under-pricing affect other firms' stock prices more adversely within the conglomerate. Next, we explored a negatively significant relation between ROE and the chaebol firms' stock returns during IPO events. Research implications - The novelty of this study is there are not many empirical studies on the impact of IPO within a conglomerate. So, the findings of this study contribute to the literature for analyzing stock's abnormal returns within a conglomerate.

  • Initial public offering (IPO) has a legal framework for investor protection, and because there are various quantitative evaluation factors, objective analysis is possible, and various studies have been conducted. In addition, crowdfunding also has several devices to prevent indiscriminate funding as the legal system for investor protection. On the other hand, the blockchain-based cryptocurrency white paper (ICO), which has recently been in the spotlight, has ambiguous legal means and standards to protect investors and lacks quantitative evaluation methods to evaluate ICOs objectively. Therefore, this study collects online-published ICO white papers to detect fraud in ICOs, performs ICO fraud predictions based on BERT, a text embedding technique, and compares them with existing Random Forest machine learning techniques, and shows the possibility on fraud detection. Finally, this study is expected to contribute to the study of ICO fraud detection based on quantitative methods by presenting the possibility of using a quantitative approach using unstructured data to identify frauds in ICOs.

  • This study aims to determine the factors that affect dividends initiation by initial public offering firms in Malaysia. The ownership structure is examined from a corporate governance theoretical perspective in order to evaluate the impacts of managerial, institutional, and family ownership on the dividend's initiation decision of IPO firms. This study employs a quantitative pooled cross-section of 372 Malaysian IPO companies active during the period of 2002-2013. The number of firms that went public each year varies, thus the pooled cross-section data takes place in this case rather than the panel data. The logistic model was employed to test the proposed hypotheses. The results revealed that the presence of institutional investors in the ownership structure make it more likely for IPO firms to initiate dividends. On the contrary, the presence of a family ownership structure in IPO companies as the controlling shareholder makes these companies less probable to initiate dividends. Managerial ownership was found to have no effect on the decision of initiating dividends by IPO firms. The findings of this study suggest that the existence of institutional and family ownerships are agency cost mitigators, as these ownership types could prompt IPOs firms to initiate dividends to overcome the agency conflicts.

  • This study analyzes the earnings management that can occur in the process of public offering in the process of SMEs reducing cost of capital, risks and seeking opportunities for direct financing. Since a company is subject to strict supervision during the IPO process, it is possible to prevent the phenomenon that the company value evaluated in the market is underestimated, or to perform earnings management in consideration of overestimation. This study attempted to verify the degree of earnings management through discretionary accruals and actual earnings management values that can affect the earnings ratio of the IPO of a company. For this study, total accruals were calculated and analyzed through discretionary accruals, sales, costs, and actual earnings management adjustments from production activities. As a result of the analysis, discretionary accruals, which are the countermeasures for earnings management during the listing process, have a positive(+) relationship in both the stock price return and the sales adjustment value, which can be viewed as a factor that induces high valuation. As a result of this, there may be a risk of adverse selection for the benefit amount, and information asymmetry may exist for public offering stocks. This study can provide useful guidelines for evaluating corporate value to domestic SMEs and investors that do business with Chinese companies as well as China through the current and type of earnings management of Chinese listed companies.
