Since the Intelligence Co., Ltd. Case, stock price calculation based on regression analysis has been increasingly used to calculate stock purchase prices in matters involving the amount of compensation for damages incurred through false disclosure and the exercise of stock purchase rights. The seminar used academic research and practical applications in Japan and the U.S. to explain the basic concept of calculating stock prices using regression analysis, as well as the matters to take into consideration when examining analysis/calculation outcomes, and made reference to the REX Holdings Case.
