 TWSE TAIEX Series Compiled by TWSE
 
 .Introduction

 TWSE, Taiwan Stock Exchange Corporation, maintains stock price indices, to allow investors to grab both overall market movement and different industrial sectors' performances conveniently. The indices may be grouped into market value indices and price average indices. The former are similar to the Standard & Poor's Index, weighted by the number of outstanding shares, and the latter are similar to the Dow Jones Industrial Average and the Nikkei Stock Average. The Taiwan Stock Exchange Capitalization Weighted Stock Index ("TAIEX") is the most widely quoted of all TWSE indices. The base year value as of 1966 was set at 100. TAIEX is adjusted in the event of new listing, de-listing and new shares offering to offset the influence on TAIEX owing to non-trading activities.

 TAIEX covers all of the listed stocks excluding preferred stocks, full-delivery stocks and newly listed stocks, which are listed for less than one calendar month.

The other market value indices are calculated and adjusted similarly to that of TAIEX only with different groupings of stocks included for calculation. Non-Finance Sub-Index, Non-Electronics Sub-Index, and Non-Finance Non-Electronics Sub-Index include stocks in non-finance sector, non-electronics sector, and non-finance & non-electronics sector, out of the TAIEX Component Stocks.

The Industrial Sub-Indices are calculated for different industrial sectors. Starting December 1986, eight Industrial Sub-Indices were introduced, i.e. Glass and Ceramic, Textile, Food, Plastic and Chemical, Electrical, Paper and Pulp, Building Material and Construction, Finance and Insurance. In August 1995, TWSE introduced additional 14 Industrial Sub-Indices, i.e. Cement, Plastic, Electric Machinery, Electric and Cable, (Chemical, Biotechnology, and Medical Care), Glass and Ceramic, Iron and Steel, Rubber, Automobile, Electronics, Shipping and Transportation, Tourism, Trading and Consumers' Goods, Other. In July 2007, TWSE also introduced additional 11 Industrial Sub-Indices, i.e. Chemical, Biotechnology and Medical Care, (Oil, Gas and Electricity), Semiconductor, Computer and Peripheral Equipment, Optoelectronic, Communications and Internet, Electronic Parts/Components, Electronic Products Distribution, Information Service, Other Electronic. This expansion is to give a broader perspective of industrial performances and a more comprehensive comparison with the overall market trend.
