The indices compiled by the Taipei Exchange include the Taipei Exchange Capitalization Weighted Stock Index (TPEX), the Electronics Sub-Index, and other Industrial Sub-Indices.

This series of indices is calculated by using the common stocks currently traded on the TPEx as the constituents and the number of issued shares as the price weights. Any changes of the above shall be adjusted to the base value to maintain the continuity of the indices. The base value is not adjusted for cash dividends, except for Total Return Index. Therefore, a fall will be observed in the market value and index on ex-dividend dates for TPEx listed stocks.
