1, main shipment: when the main stock has made a big profit after a long-term rise, it throws chips at the top and carries out the shipment operation, resulting in the stock price falling. In this case, investors should focus on selling.
2. Main dishwashing: During the rise of individual stocks, there are more retail investors in the market. In order to wash away the retail investors in the market and reduce the pressure of rising stocks in the later period, the main force will use the chip advantage to buy some stocks first, raise the stock price, and then sell them above.
Let the retail investors in the market mistakenly think that the main force is shipping, throwing out the chips in their hands, causing the stock price to fall. When the retail investors in the market are almost washed, the main force will be taken back below.
