Follow the lifeline. Buy the stock if it stands firm on the lifeline, and sell if it falls below the lifeline. When choosing among the 3 stocks, I choose those with performance support. 4. When the stock price hovers above the lifeline, focus on the current macroeconomic situation and the shape of each indicator. If there is a trend of weakening or passivation, you should be alert.
