When the time-sharing line rises, the average price line also rises, which means that the time-sharing line runs on the average price line and maintains a certain proportional relationship. When the time-sharing line rises, the average price line should keep up. If many parties hope that the price will rise, they will take the initiative to push up the stock price. At this time, the time-sharing line will continue to rise, and the average price line will continue to rise, because the average price line represents the average shareholding cost at this time.
