When I was in high school, I became interested in finance because I was concerned about current social events and because of the popularity of a novel called Currency War. Because of this interest, I chose the finance department when I filled in my volunteers. Even at the risk of being transferred to an unpopular project, I will jump into this pit without hesitation. When I was a freshman, my interest in finance was more at the macro level. Currency, foreign exchange, a series of tall words take root in my mind, but I can't connect to the Internet. They can only be used as conversation materials when chatting on the wine table during holidays. When I was a sophomore, my interest in finance came from the excitement and confusion in the investment process. Simple CAPM measures people's value judgments.
