Judgment of the stock sector:
During the formation of theme stocks or second hot plates, the following characteristics will be formed on the disk surface:
1, the trading volume of individual stocks or overall stocks increased obviously and continuously.
2. The stock price fluctuates continuously, and the market is often closed or hit at the close; This phenomenon also occurs at the beginning and middle of the meeting.
3. With the increase of turnover rate, the stock price trend of a certain sector began to turn from weak to strong. When the market falls, individual stocks and sectors do not fall. When the market rises, the sector gains more than the market, which may become a hot spot in the market.
When judging whether it is a hot plate, we should also pay attention to the following points:
1, the process of hot spot formation is the process of main capital intervention. The longer the hot spot formation time, the longer the duration, or the short duration, but the stock price of the sector has increased greatly.
It is impossible for the stock market to have too many hot spots at the same time. If there is crazy speculation in the market at the same time, we should pay attention to whether there is a signal that the market is peaking. When a new hot plate is formed, the old hot plate will be adjusted.
3. In the process of hot plate transfer, the plate will often be greatly adjusted, and the main capital institutions will adjust their position structure, share exchange and plate operation.
