Most people in a bull market think that the bull market will never end and will not fall on their heads. People in a bear market think that it is still early for the bear market and they will get on board later. As a result, they are not there when the market rises, but they are there every time when the market falls. Regardless of whether it is a bull or a bear market, remember not to chase small increases, not to add to small decreases, buy when the market falls, and sell when the market rises. Always be prepared for both, look at the market trend, and dynamically adjust the short position ratio. Never hold a full position, so that you can make money when the market falls, and you will not miss out when the market rises.
