Mid-line stocks refer to stocks with a medium holding period, which is different from short-term stocks and long-term stocks.

Mid-line stock selection can't examine the fundamentals as carefully as long-term stock selection, because it holds 1-3 months, so we should pay more attention to the trend of the stock. We can usually look at the 30-day medium-term moving average of stocks. Generally, some long-term potential stocks that have been concerned for a long time are the first choice for us to pay attention to when the main wave rises.
