This is when the stock market is mostly bearish and not optimistic about the market outlook, the bulls, that is, the bookmakers who are optimistic about the market outlook and launch the market, set off a wave of rising prices. As the market is pushed up step by step, bearish bears keep selling stocks, but bulls keep buying and continue to push up the market. However, when the bears who were not optimistic about the market outlook changed their views and thought that the stock market would continue to rise, even if the bears died, the rise would stop. On the other hand, it is "the bears are not dead, and the income is unlimited."
