Short selling: Short selling is an investment term and a way of operating financial assets. Contrary to bulls, bears borrow the underlying assets first, then sell them to get cash. After a period of time, they spend cash to buy the underlying assets and return them. The common functions of shorting are speculation, financing and hedging. Among them, short-selling speculation means that if the market is expected to fall in the future, it will sell high and buy low, and sell the borrowed stocks at the current price, and then buy them back after the market falls to obtain the difference profit. Its trading behavior is characterized by selling first and then buying. In fact, it is a bit like the credit transaction model in business. This model can profit in the wave band of falling prices, that is, borrowing goods at a high level and selling them, and then buying and returning them after falling. In foreign exchange trading and stock trading markets, the word "long and short" is very common.
Good and bad. News and factors that are beneficial to bulls and can stimulate the stock price to rise are called "bullish". For example, listed companies have overfulfilled their profit plans and the macro-economy is running well. Factors and news that are beneficial to bears and can lead to a decline in stock prices are called "bad". Such as the poor management of joint-stock companies, the increase in bank interest rates, natural disasters and man-made disasters that affect the operation of listed companies, and so on.
