Extended data:
1, and the index calculation formula is
Today's index = (total market value of today's index stocks/total market value of benchmark index stocks) × benchmark index.
B shares in the index stocks are converted into RMB at the average exchange rate adjusted by foreign exchange last week, which is used to calculate the Shenzhen Composite Index and Shenzhen Component Index. Shenzhen B-share index and component B-share index are still calculated in Hong Kong dollars.
After the end of call auction on each trading day, the opening index is calculated by using the opening price of the stock generated by call auction (yesterday's closing price is taken if there is no transaction), and then the real-time index is calculated in a chain way until the closing.
2. Calculation formula of daily chain ratio:
Today's real-time index = closing index of the previous day × (total market value of today's real-time index stocks/adjusted total market value of the previous day's index stocks)
Total market value of index stocks = total market value of index stocks A shares+total market value of index stocks B shares.
Total market value of index A shares = σ (share price of index A shares × number of index A shares).
Total market value of index B shares = σ (share price of index B shares × number of index B shares) × average exchange rate of foreign exchange adjustment last week.
The fund index is calculated in the same way as the constituent stock index, and the weight is the number of new fund units directly listed on the Shenzhen Stock Exchange (that is, the number of circulating fund units).
