Summary
Masayuki Kubota’s book highlights the critical difference between successful and unsuccessful stock investors: decision-making during losses. Many investors sell profitable stocks prematurely while holding onto underperforming ones due to emotional biases. Kubota emphasizes the importance of understanding stock charts as reflections of collective market behavior, not tools for predicting the future.
