I have recommended "The Crowd" and "Behavioral Finance" several times before, but people with less investment experience may not understand them, and most people may find them boring, especially "Behavioral Finance". The water sensation is the most important, and people who have not watched swimming tutorials can basically learn it as long as they can practice in the water. It's just a matter of threshold or mastery. But people who only follow swimming tutorials without going into the water cannot learn how to swim. It would be better to read these books after gaining experience in diving. I only saw these books after having a mature trading system, and I found them very resonant. As a theoretical foundation, everyone can take a look. In addition, I have also shared many personal understandings, real-time cases, and summaries of emotional trading in real time along the way. If you read them systematically, it will be more relevant, as many of them have been experienced by everyone. The underlying of emotional trading is human nature, and humans cannot be absolutely rational. There will be emotional fluctuations, and most people will be influenced by market price fluctuations, holding costs, and other people's opinions on their emotions during the investment process, which will then be reflected in the price, causing the price to deviate from its intrinsic value. Moreover, the rule of the road is that a few people earn the money of the majority, and individual integration into the group will reduce intelligence. Since a minority earns money from the majority, the emotions of the group are very important. Emotional trading is about rationally recognizing the irrational emotional behavior of a group and going against it.
