Short-term is an investment term such as stock futures, which refers to the behavior of turning the stock price into bearish in a short time, borrowing shares to sell, and making up for the increase in a short time. For example, when you expect a stock to fall in the future, sell the stock you don't own when the current price is high, and then buy it when the stock price falls to a certain extent, so the difference is your profit. The definition of shorting is the same as shorting, except that shorting is a short-term behavior, which can be a week or three days.
