At that time, all I could think about was "the good news is exhausted, it's bottoming out and rebounding," which is a classic case of confirmation bias.According to Munger's "inverse thinking," I should have asked myself: "Under what circumstances would this trade bankrupt me?"1. Has the industry's fundamentals truly reversed? (There was no evidence at the time)2. Was I only paying attention to information that supported my position because I was already holding the stock? (Confirmation bias)The review revealed that my buying logic at the time was full of holes, completely focused on "making money" while ignoring the prerequisite of "not losing money."【Behavioral Change】Now, there's an additional step in my trading process: before placing every order, I must list three reasons "why this trade will fail." If I can't refute these three reasons, I don't act.What Munger taught me is: rather than searching for mediocre opportunities, it's better to first eliminate the obviously stupid ones." datetime: "2026-02-20T15:33:54.000Z" locales: - [en](https://longbridge.com/en/topics/38806213.md) - [zh-CN](https://longbridge.com/zh-CN/topics/38806213.md) - [zh-HK](https://longbridge.com/zh-HK/topics/38806213.md) author: "[红树街交易员李华](https://longbridge.com/zh-HK/profiles/14753423.md)" --- > 支持的語言: [English](https://longbridge.com/en/topics/38806213.md) | [简体中文](https://longbridge.com/zh-CN/topics/38806213.md) # Before reading "Poor Charlie's Almanack," … ### 相關股票 - [Richtech Robotics - B (RR.US)](https://longbridge.com/zh-HK/quote/RR.US.md) ## 評論 (1) - **咱们复利有力量 · 2026-02-20T23:52:33.000Z · 👍 1**: Similarly
