Is going short at the bottom a good thing or a bad thing?

If the stock falls at a low level and the volume is high, it is a bad thing if all sell orders are placed, and the stock price may be suppressed by short orders. If there is a lot of buying in the market, the main force will raise it first and then kill it. If there is less buying in the market, the main force will directly kill the goose to lay eggs. This will cause the stock market to plummet for several days or dozens of days. In the end, individual stocks will often fall beyond recognition. The main force can obtain as much funds as it can. It can be seen that a heavy volume decline at the bottom is also a bad thing for investors.
