At his peak, Peter Lynch's managed company held 1,500 stocks. These stocks were basically all researched by him on-site, so the success rate was very high. As a methodology, this approach is certainly sound, but as ordinary people, we can't conduct so many on-site investigations like an investment company. Therefore, I've always agreed with one saying: whether it's Warren Buffett, Duan Yongping, Value Brother, or anyone you admire, you can only look for "commonalities." Ultimately, the investment system must be combined with one's own "individuality," which includes everything about oneself—from childhood to adulthood, from inside out, from life to career. I wish everyone can form their own investment system soon, and I also wish myself to complete this task as soon as possible🤔
