About TAIEX
The TAIEX (Taiwan Capitalization Weighted Stock Index) covers all listed common shares on the Taiwan Stock Exchange. Semiconductor giant TSMC is by far its largest constituent, meaning the index moves closely with the global chip cycle. Foreign institutional flows into and out of Taiwanese tech are among Asia's most watched daily risk-appetite indicators.

History & Index Methodology
TAIEX is calculated in real time from the prices of its constituent stocks, typically weighted by free-float market capitalisation so that larger, more liquid companies carry more influence. The constituent list is reviewed periodically by the index provider, with companies added or removed based on size, liquidity and listing criteria. Long-run index history lets analysts compare today's level against decades of market cycles.

Trading Hours
TAIEX trades 06:30 AM to 11:00 AM IST (09:00–13:30 Taiwan time), Monday to Friday. Outside those hours this page shows the last traded level, with change figures measured against the previous official close. All session times are expressed in Indian Standard Time (IST).
How to Read TAIEX
Watch TAIEX's level against its previous close for the day's direction, and against the 50-day and 200-day moving averages for the medium-term trend. A print near the top of the 52-week range with rising volume is often read as momentum by market participants, while repeated failures at the same level mark resistance. Breadth — how many constituents rise versus fall — shows whether a move is broad-based or driven by a few heavyweights.
52-week range: 23,885.41 – 48,218.871.

TAIEX — Taiwan's Headline Equity Index
The TAIEX (Taiwan Capitalization Weighted Stock Index) is the headline benchmark for the Taiwan Stock Exchange (TWSE), covering essentially all listed common shares — more than 900 constituents. The index is capitalization-weighted with a base value of 100 set in 1966, making it one of Asia's longest continuously published benchmarks. Its defining feature is extreme single-stock concentration: Taiwan Semiconductor Manufacturing Company (TSMC) alone accounts for roughly 30-35% of index weight, with Hon Hai Precision (Foxconn), MediaTek, Delta Electronics, Quanta Computer and Fubon Financial rounding out the major weights.
For global investors, the TAIEX is the purest large-cap proxy for the world's semiconductor supply chain. TSMC fabricates the majority of the world's leading-edge chips — including virtually all high-end AI accelerators — so the TAIEX responds to AI-capex announcements, US chip-export policy and foundry pricing cycles before most other national benchmarks. The Taipei cash session runs 06:30-11:00 IST, closing before Nifty's morning settles, which makes the TAIEX (alongside the Nikkei and KOSPI) an early tech-sentiment read for Indian IT and electronics-manufacturing names.
History & contract origins
The TAIEX was launched in 1967 with a 1966 base value of 100. Its most famous episode is the 1990 bubble and crash: fuelled by trade-surplus liquidity and retail speculation, the index rocketed to 12,682 in February 1990, then collapsed roughly 80% to 2,485 within eight months — one of the deepest drawdowns any major market has recorded. The 1990 high stood for three decades until the index finally broke it in July 2020, powered by the global semiconductor super-cycle.
Major drawdowns: 1990 bubble burst (-80%), 1997 Asian financial crisis (-45%), 2000 dot-com (-66%), 2008 GFC (-58%), 2020 COVID (-30%), 2022 tech derating (-33%). The 2023-2025 AI-infrastructure boom drove the TAIEX to successive all-time highs as TSMC's data-centre chip revenue accelerated, cementing the index's status as the primary listed vehicle for AI-hardware exposure in Asia.

How to read this tape
Three lenses for reading the TAIEX. First, the global semiconductor cycle: TSMC's monthly revenue releases (published around the 10th of each month) and quarterly capex guidance are the single biggest index catalysts; the Philadelphia Semiconductor Index (SOX) and TSMC's US-listed ADR (TSM) lead the Taipei open almost mechanically. Second, the Taiwan dollar (TWD/USD): TAIEX heavyweights are exporters, so a weak TWD flatters earnings, though large foreign-investor flows often strengthen the currency and lift the index simultaneously during tech up-cycles. Third, cross-strait and US-China chip policy headlines — export-control announcements or geopolitical escalations produce sharp, gap-style moves that regional indices then follow.
Foreign institutional investors hold roughly 40% of TWSE free float, and their daily net-buy / net-sell figure (published every afternoon) is one of Asia's most watched real-time risk-appetite indicators. Persistent foreign selling of TSMC has historically been an early warning for broader emerging-Asia tech weakness — including Indian IT.
Frequently asked questions
Why does TSMC dominate the TAIEX?
TSMC is by far Taiwan's largest company — its market capitalisation (well above $800B in 2026) exceeds the next ten TWSE listings combined. In a cap-weighted, all-share index that translates to a 30-35% weight, the highest single-stock concentration among the world's major national benchmarks.
What time does the Taiwan market open in IST?
06:30 IST for the cash open (09:00 Taipei time), closing at 11:00 IST (13:30 Taipei). The session runs continuously with no lunch break, unlike Tokyo, Shanghai and Hong Kong.
Is the TAIEX a good signal for Indian markets?
For technology sentiment, yes. The TAIEX closes before India's morning session settles, and its direction — driven by TSMC and the AI-hardware complex — often telegraphs how global tech trades that day. Indian IT services and electronics-manufacturing (EMS) names show meaningful correlation during semiconductor-cycle inflection points.
Why did the TAIEX take 30 years to reclaim its 1990 high?
The February 1990 peak of 12,682 was a classic liquidity bubble — the market traded at extreme valuations on speculative retail flow. After the 80% crash, it took decades of earnings growth, the rise of TSMC into the world's dominant foundry, and the 2020 semiconductor super-cycle for the index to finally clear 12,682 in July 2020.
Can Indian residents invest in the TAIEX?
Yes, via the LRS route through international brokers. The most practical vehicles are EWT (US-listed iShares MSCI Taiwan ETF) or TSMC's NYSE-listed ADR (TSM) for concentrated exposure. Direct TWSE access requires a Taiwanese brokerage account, which is uncommon for retail foreign investors.
