Abstract
It is pointed out that remittances and loans to individuals by promoting FinTech will be replaced by FinTech companies' service, which are cheaper and more convenient, and it will become more difficult for existing financial institutions to earn by commission. However, city banks believe that not FinTech companies but city banks can promote FinTech. This research aims to analyze the evaluation of the stock market for the promotion of information technology such as FinTech and Cloud in the banking industry. By looking at the market valuation you can confirm the difference between the banking industry and the shareholders. For the analysis, we use the method of event study.
