2. Short-selling stocks become bulls. Shorting stocks really hopes that stocks will rise because they see the possibility of rising.

3. Both short positions and long positions are lightening positions, which means that the market will fall, not necessarily, depending on how many short positions or long positions are lightening positions.

Summarize; Shorting is short-selling, that is, selling all the stocks that make money in your hand, and then buying them when they fall, so that you can make money; Short selling has a great influence on the market, because they are not optimistic about the stock market, but they are all selling, so they have to fall and fall until the price of short sellers is low, but once they buy, they will stop falling and rise again.
