The Taiwan Stock Exchange (TWSE) was founded in 1961 and commenced trading in February 1962, transitioning to a fully automated system in 1993 and introducing intraday continuous trading in March 2020. The main market benchmark is the Taiwan Capitalization‑Weighted Stock Index (TAIEX), commonly referred to as the Taiwan Weighted, tracking the aggregate performance of all listed common shares.
As a major semiconductor and technology hub, the Taiwan’s stock market offers exposure to cutting‑edge tech and global supply chains. Notably, Taiwan Semiconductor Manufacturing Company Limited (TSMC) is ranked first among the top 10 constituents of the MSCI Emerging Markets Index in 2025, holding 11.89% of the float‑adjusted market capitalization.
To capitalize on this opportunity, stakeholders require accurate and comprehensive data that is unique to Taiwan, preventing reporting biases to keep up with market‑moving flows for research, portfolio allocation, strategy execution, and more decisions.
