Starting from behavioral finance, this book studies the behavioral deviations that often occur due to greed, fear, and overconfidence in the investment process of individual enterprises and institutional investors, including chasing bubbles for high returns and satisfying the personal interests of executives. While ignoring the company’s long-term benefits, deliberately misleading investors and regulators in order to push up the stock price, and citing a wealth of research cases for supplementary explanation. I hope this book can help entrepreneurs, policy makers, and investors better understand themselves, better understand their own investment philosophy and investment strategies, so as to obtain higher investment returns.
