1. SSE Composite Index
(a) SSE Indices are all calculated using a Paasche weighted composite price index formula.
(b) Composite Indices and Sector Indices are weighted by shares.
The formula is
| Current index = |
Current total market cap of constituents |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Total market capitalization = Σ (price × shares issued)
(c) B share Price unit
B share stocks are denominated in US dollars when B share index are calculated. For calculation of other indices, B share stock prices are converted to RMB at the applicable exchange rate (the middle price of US dollar on the last trading day of each week) at China Foreign Exchange Trading Center.
2. SSE New Composite Index
(a) SSE Indices are all calculated using a Paasche weighted composite price index formula.
(b) Composite Indices and Sector Indices are weighted by shares.
The formula is
| Current index = |
Current total market cap of constituents |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Total market capitalization = Σ (price × shares issued)
(c) B share Price unit
B share stocks are denominated in US dollars when B share index are calculated. For calculation of other indices, B share stock prices are converted to RMB at the applicable exchange rate (the middle price of US dollar on the last trading day of each week) at China Foreign Exchange Trading Center.
3. SSE A Share Index
(a) SSE Indices are all calculated using a Paasche weighted composite price index formula.
(b) Composite Indices and Sector Indices are weighted by shares.
The formula is
| Current index = |
Current total market cap of constituents |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Total market capitalization = Σ (price × shares issued)
(c) B share Price unit
B share stocks are denominated in US dollars when B share index are calculated. For calculation of other indices, B share stock prices are converted to RMB at the applicable exchange rate (the middle price of US dollar on the last trading day of each week) at China Foreign Exchange Trading Center.
4. SSE B Share Index
(a) SSE Indices are all calculated using a Paasche weighted composite price index formula.
(b) Composite Indices and Sector Indices are weighted by shares.
The formula is
| Current index = |
Current total market cap of constituents |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Total market capitalization = Σ (price × shares issued)
(c) B share Price unit
B share stocks are denominated in US dollars when B share index are calculated. For calculation of other indices, B share stock prices are converted to RMB at the applicable exchange rate (the middle price of US dollar on the last trading day of each week) at China Foreign Exchange Trading Center.
5. SSE 180 Index
SSE 180 Index is weighted by adjusted number of shares.
The formula is
| Current index = |
Current adjusted market cap of constituent |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Adjusted market cap = Σ Price X Adjusted No. of shares.
Adjusted market cap of constituents on the base day is also called divisor. SSE 180 Index uses category-weighted method (as indicated by the following chart) to adjust constituents' sharers. For example, a stock with a negotiable market share ratio (negotiable market cap /total market cap) of 7%, which is below 10%, will have a weight equals to its negotiable market capitalization ratio. A stock with a negotiable market share ratio of 35% will belong to category (30, 40). The corresponding weight is 40%, i.e. 40% of total market share will be used for index calculation.
6. SSE 50 Index
SSE 50 Index is calculated using a Paasche weighted composite price index formula and weighted by adjusted number of shares.
The formula is
| Current index = |
Current adjusted market cap of constituents |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Adjusted market cap = Σ Price × Adjusted No. of shares.
SSE 50 Index uses category-weighted method (as indicated by the following chart) to adjust constituents' sharers.
7. SSE Dividend Index
SSE Dividend Index is weighted by adjusted number of shares.
The formula is
| Current index = |
Current adjusted market cap of constituent |
× Base Value |
| ------------------------------------------------ |
| Base Period |
Adjusted market cap = Σ Price X Adjusted No. of shares.
Adjusted market cap of constituents on the base day is also called divisor. SSE Dividend Index uses category-weighted method (as indicated by the following chart) to adjust constituents' sharers. |
