Each stock has its own region, called the regional plate; Every company has its own job, which is an industry attribute, that is, an industry index; In addition, there are many concepts, although companies in different industries can belong to military industry and high-end equipment. This is a concept plate that can continue to rise.

Straight flush index is calculated by equal weight method according to the component stocks corresponding to the plate, that is, the time-sharing increase of the index is the arithmetic average of the time-sharing increase of the corresponding component stocks. If the constituent stocks are suspended, they will not participate in the index calculation; When the turnover rate of newly listed constituent stocks in a certain sector is greater than 1%, they will participate in the index calculation on the next trading day. During the period of call auction (9: 15-9:24), the index is calculated according to the virtual opening reference price of the constituent stocks, and the continuous bidding period (after 9:25) is calculated according to the latest price of the constituent stocks. The plate list starts to show the plate increase in call auction, which can help you to know the hot spots of the day 10 minutes in advance.
