TAIEX (Taiwan Capitalization Weighted) Index — Level, Chart & Constituents

What the TAIEX (Taiwan Capitalization Weighted) measures

The TAIEX (Taiwan Capitalization Weighted) is a stock market index that tracks the performance of the largest companies listed on the Taiwan Stock Exchange. As a capitalization-weighted index, each company's influence on the index level is proportional to its total market value, meaning larger firms move the index more than smaller ones. It is part of the broader Asia-Pacific region and is often compared with peers such as the Nikkei 225, the Hang Seng Index, and the KOSPI. The TAIEX serves as a barometer for Taiwanese equities and a window into the technology-heavy export economy of Taiwan.

Key numbers explained

• The index currency is TWD (New Taiwan Dollar), meaning the level is quoted in local currency; foreign investors also watch the exchange rate when converting returns.
• The market classification WORLD and sector Asia-Pacific place the index in a global context, alongside regional benchmarks like the Shanghai SSE Composite and the S&P/ASX 200.

What to watch

Broad factors that typically move a capitalization-weighted equity index include corporate earnings reports, monetary policy decisions by central banks, shifts in global trade flows, and geopolitical developments affecting the region. Because the TAIEX is heavily weighted toward technology and export-oriented firms, global demand cycles and supply-chain developments can be especially relevant. Currency movements of the TWD against major currencies also influence returns for international investors. For a wider view of the region, investors often monitor the Hang Seng TECH Index and the IDX LQ45 alongside the TAIEX.
