For example, if I have a relatively large amount of funds and decide to raise the stock A, I will first talk to the gunmen in various media and say that A will go up. Then someone pays attention. I will use part of myself to buy the stock in the secondary market in large quantities, which will be part of the stock price rise, and I will take over my selling with the remaining funds, so that I can sell it back and raise the stock price only by paying the handling fee. When retail investors saw that A really went up, they followed suit. At this time, the stock price was pulled up by retail investors. I saw the opportunity, and then I sold my stock to raise the stock price and make money.

If I want to suppress the share price of B shares, I will also prepare a large amount of funds and then absorb shares on a small scale. After the shares in hand reach a certain number, they are sold in batches, causing the stock price to fluctuate downwards. At the same time, the message that B will fall was conveyed through the media. After retail investors see that B has indeed fallen, some people will sell it. At this time, on the one hand, I sold the absorbed shares at a high price, on the other hand, I reabsorbed them at a low price, and finally achieved the goal of obtaining B shares at a low price.
