There is a saying on Wall Street that "bulls earn more and bears earn faster", which is of course the golden rule. The reason is that the downward angle of the stock price will be "steeper" than the upward angle, so the bears will generally fall more sharply than the bulls.
Rising comes from greed, falling comes from panic-people's desire to buy greed can be accumulated slowly. For example, if you buy clothes, you can choose them slowly all morning and be in a hurry. Once I heard the earthquake and caught fire, I rushed out without thinking, which also explained why it fell so fast.
The question you asked-Soros is the most qualified to answer your question. This short-seller has made money in the futures market all his life. If your entry point is high enough or the fund management makes the position safe, it is very fast. Because the market is fast, sometimes the position will fluctuate violently (fall a little and then pull back in the opposite direction to get rid of some heavy positions), so the most important thing to short is to accurately judge the consolidation of the head to avoid the head and get considerable profits, which is easier said than done.
