Summary
Masayuki Kubota, a seasoned fund manager, emphasizes the importance of identifying the ‘initial surge’ in stock trading. His book, Stock Trade, provides a practical guide for investors to recognize profitable opportunities. The strategy involves targeting stocks that transition from low activity to sudden trading volume spikes, signaling a potential upward trend. For example, A Company represents an ideal buying opportunity with its early upward movement and increased trading volume. In contrast, B Company shows declining interest, and C Company poses risks due to overbought conditions. Kubota advises buying during the ‘initial surge’ and holding as long as the upward trend persists. This approach is designed to help investors maximize returns while avoiding high-risk scenarios.
