The stock in a public offering refers to stocks that are sold to an unspecified public to be listed on the KOSPI or the KOSDAQ market. Because the initial public offering (IPO)’s closing price of offering day mostly tends to rise opposed to the offering price of it, which is selling price, it is a good alternative investment asset in the low interest rate period. However, it is difficult for individual investors to obtain and analyze information on public offerings and IPO stocks compared to institutional investors. Therefore, this paper confirms whether individual investors can predict the rise and fall of the IPO’s closing price of offering day compared to its offering price by using multiple data analysis methodologies and non-financial data that is relatively easy to collect, and compares the accuracy of them. Logistic regression, discriminant analysis, decision tree, artificial neural network, case based reasoning, and support vector machine were used for analysis, and the empirical experiments was conducted using the IPO data from 2007 to September 6, 2017.
