If 1 and K-line continue to fall, it is an obvious selling signal, especially when the stock price goes up and then falls. We can accurately judge that this is caused by the main force in the shipment. The main shipment, retail natural follow-up, or quilt cover.

2. When the stock price continues to fall after a long-term sharp rise, don't feel bad about the stock price, and don't hold the mentality that the stock price is picking up. Be sure to clear the warehouse immediately.

3. When the stock price rebounds in the downward trend, and falls more than once in the later period of the rebound, it is necessary to go out and wait and see in time.

4. When the stock price reaches the bottom of the downward trend and shows a downward trend, you can appropriately lighten your position and buy when the stock price reaches the bottom.

The decline caused by market turbulence or market downturn is common, but it is not only rare. Therefore, if you encounter a decline caused by the main shipment, you should quickly sell the stop loss.

1. Concept stocks refer to stocks with certain special connotations, as opposed to blue-chip stocks. Blue-chip stocks need good performance support. Concept stocks rely on a certain theme, such as the concept of asset reorganization and the concept of three links to support prices. This connotation is usually regarded as a theme of stock selection and speculation, and has become a hot spot in the stock market.

Second, concept stocks are stock market terms, as a way of stock selection. Compared with blue-chip stocks, they must have good business performance support, and concept stocks are only a combination of stocks with the same theme and type. Because of the advertising effect of concept stocks, there is no guarantee of any profit.

Third, the concept of the stock market was originally a general term for a class of stocks with the same characteristics. For example, the Olympic concept refers to a group of companies that have business opportunities to host the Olympic Games. There are many such concepts, such as network concept, 3G concept, WTO concept, biomedicine concept, whole listing concept, stock index futures concept, but in the stock market, the internal meaning of the concept is not only a generalization of a certain stock category, but its extended meaning is a kind of market knowledge. For example, the concept of network, before the network became a concept, the stocks involved in the Internet could only be called plates at best, which was a neutral definition, but the meaning of becoming a concept changed. This concept is a relatively positive investment knowledge. Investors will make very detailed analysis and research on the industry background, investment opportunities and future prospects of concept stocks, and they are not always confident to report them.
