Short positions are often used by stock experts, and ordinary investors really won't use them. Because the master only buys stocks when the opportunity to make money is clear. Usually they are empty positions, watching the stock market for opportunities like a hungry wolf. Buy stocks when you have the chance. After buying shares, I found that there was a risk and ran away immediately. In this way, you will always be empty.
Novices often can't control their own hands, and they can't help buying stocks if they have some money in their accounts. The opportunity to buy stocks is unreliable, and you will be caught if you buy them.
Therefore, whether there will be short positions can be seen from the operational level of investors.
