Actually, during the second half of a bear market, as it progresses towards its deepest bottom, there will still be several short-term buying opportunities, given the successive waves of price increases. However, I don't recommend ordinary people try this, as it's very risky. It's difficult for the average person to buy at the absolute bottom, and they might be reluctant to sell after a slight rise, turning potential profits into losses, or even incurring direct losses by chasing highs… Predicting the exact points of a sharp drop is also very difficult; I certainly don't have the experience to say I can predict it definitively. It's all about luck.
