Hello, long-term fund refers to the following nature: since most stock funds require that the position of stocks be no less than 60%, if this determines that stock funds are generally long-term, then such stock portfolio is long-term if the position is higher than 60%. Simply put, a bull is a person who makes long futures (first buy at a low price and then sell at a high price). Short position is that investors and stock traders think that although the current stock price is high, it is not good for the stock market prospect, and they expect the stock price to fall, so they sell the stock and buy it when the stock price falls to a certain price to obtain the difference income.

The above is my answer, I hope I can help you, I hope I can adopt it, thank you!
