Active funds generally refer to the main players who are optimistic about the stock and take the initiative to buy funds. The main funds refer to the main funds in the stock, which are generated in the process of alternating stock management, and will guide the trend of the stock to a certain extent. Several stages of major capital operation: 1. Collecting chips, stock trends and trading volume are relatively dull; 2. The stock price rises, the stock price rises sharply, and the trading volume expands; 3, profit transportation, after the main profit is sold, the stock price does not drop much at this time. 4, after the transportation is completed, the retail investors take over, the stock price drops rapidly. Active net buying generally refers to that the main stocks are optimistic about the later market, actively buying and increasing the number of stocks. The main funds refer to the number of major funds in the stock, which is generated in the process of stock alternating operation. To a certain extent, active net buying is positively related to the main funds, that is, the main net buying volume increases.

when the active net purchase increases and the main capital flows into the state, the market is mainly willing to raise the stock price, which will stimulate market investors to follow the trend and promote the stock price to rise, which is a buying signal; When the active net purchase decreases and the main funds flow out, the main stocks are not optimistic. In the transportation operation, it causes market investors to panic and sell stocks, which leads to a decline in stock prices. It is a sales signal. < P > The main net purchase represents the number of major positions increased today, that is, the number of floating chips in the market is less. The main fund often operates stocks alternately. On the one hand, it needs to buy some chips to guide the rise in order to make the stock price rise. On the other hand, it needs to actively sell some chips to suppress the stock price so that it can attract funds. Therefore, major net purchases and major funds often complement each other.

in the operation of a stock, if the main force pulls harder today, then the net purchase of the main force will be greater. If the main force is serious today, the net sales of the main force will be even greater. But in practice, we can often see that the main funds are out of sync with the main net purchases. For example, the main capital outflow is relatively large, but the main net purchase is relatively large, and the main capital outflow is relatively small, but the main net sales are relatively large.
