About TAIWAN WEIGHTED
Taiwan Weighted Index
The Taiwan Weighted Index, or TAIEX is the primary index for Taiwan. It was launched in November 1970. It tracks the largest companies listed on the Taiwan Stock Exchange (TWSE). It follows the capitalisation-weighted method for including stocks in the index. So, a company's weightage in the index is proportional to its market value.
Features of Taiwan Weighted Index
Here are some key features of the Taiwan Weighted Index:
- Sensitive to a sector: The TWII Index is highly sensitive to the performance of the technology industry of Taiwan.
- Economic Indicator: It is considered as a major indicator of Taiwan's overall economic conditions.
- Benchmark Usage: TWII is often used as the benchmark for investment instruments such as mutual funds and ETFs.
Eligibility Criteria for Stock Selection in Taiwan Weighted Index
The stocks are included in the TWII based on the following criteria:
- Only the common stocks listed on TWSE are eligible.
- New stocks must be listed for at least one calendar month.
- Preferred stocks and full delivery shares are not included. Full delivery shares are included when they get the regular trading status.
- Stocks suspended for trading are excluded. They will be included one month after they are traded again.
TAIEX Index Calculation Method
Taiwan Stock Exchange (TWSE) uses the following method to calculate the TAIEX Index:
- First the End-of-Day index is calculated once a day after the market closes. However, the "Price Index" is calculated every five seconds based on the most recent prices of stocks during trading hours of the TWSE's centralised securities exchange market.
- To reflect the return that includes reinvesting the cash dividend, the "Total Return Index" is adjusted. The cash dividend factor is considered for this purpose.
- Now the index is calculated using the formula:
Index = Aggregate market value / Base value of the current day * 100
Where,
Total market value is the product of each stock's price and the total number of shares issued.
The annual average of 1966 is the base of TAIEX, with a base value of 100 points.
Note, that the opening auction reference price may be used for calculation if trading price isn't available on that day. On the other hand, the number of listed shares may be used for new stocks included in the index.
