Taiwan Stock Exchange Chief Says Look Beyond TSMC

Key takeaways

• Taiwan Stock Exchange chairman Sherman Lin wants investors to look beyond TSMC and value the island as a connected technology ecosystem.
• TSMC represents more than 40% of Taiwan’s benchmark TAIEX, creating extraordinary market concentration even as it anchors a much wider supply chain.
• Taiwan recorded 70 IPOs across its two exchanges in 2025, raising a record $3.3 billion; about 40% came from the AI supply chain.
• The exchange is using its Innovation Board, a new non-electronics index and disclosure reforms to make smaller “hidden champions” easier for global investors to find.

The Taiwan Stock Exchange is trying to turn global attention on TSMC into investment across Taiwan’s wider technology network. Chairman Sherman Lin argues that investors are not buying exposure to one chipmaker alone. They are buying into a compact supply chain spanning chip design, foundries, testing, servers, components, cooling, networking and specialist manufacturing.

The pitch addresses a genuine concentration problem. Taiwan Semiconductor Manufacturing Company, or TSMC, accounts for more than 40% of the benchmark TAIEX. One disappointing trading session in the chipmaker can therefore pull down the whole index even when hundreds of other listed businesses have not changed.

Taiwan’s market story is both concentrated and diverse: TSMC dominates the index, but its strength depends on an ecosystem of suppliers and customers that the exchange now wants investors to value on their own merits.

Why the Taiwan Stock Exchange wants investors to look beyond TSMC

TSMC is the world’s leading semiconductor foundry, which means it manufactures chips designed by customers such as Apple, Nvidia and AMD. Its scale, advanced processes and profitability make it the first Taiwanese company many global investors recognise.

That success has helped Taiwan’s market reach a new level. Bloomberg calculations cited by Fortune showed Taiwan overtaking India in May 2026 to become the world’s fifth-largest stock market. Lapaas Voice covered the same milestone in its report on Taiwan overtaking India by market capitalisation.

Yet size does not eliminate concentration. Fortune reported that TSMC represented over 40% of the TAIEX and as much as 60% of the MSCI Taiwan Index. MediaTek, the second-largest company in the MSCI index, held only about a 5% weight. That gap means international funds can treat Taiwan as a one-company market even when the underlying economy is more varied.

Lin’s answer is not to minimise TSMC. He calls it Taiwan’s most iconic company. Instead, he wants investors to understand why TSMC can perform at that level: suppliers are close, engineers move through a mature industrial network and manufacturers can solve problems quickly across a corridor running from Taipei through Hsinchu and Taichung to Kaohsiung.

The “technology island” mechanism

Lin describes Taiwan as a “technology island” and compares it with an industrial park. The phrase points to physical proximity as well as sector expertise. A chip design can move through fabrication, packaging, testing, assembly and final equipment makers without every participant building capabilities from scratch.

The ecosystem also extends beyond semiconductors. Taiwanese firms produce servers, networking equipment, power systems, cooling components, displays, circuit boards and electronics for global brands. AI infrastructure depends on all of these layers, so demand for accelerators can spread through suppliers that never sell a consumer-facing chip.

This clustering is the mechanism behind Lin’s investment pitch. A standalone factory can buy modern equipment, but it cannot instantly reproduce decades of supplier relationships, engineering knowledge and operational trust. Taiwan’s advantage lies in the network, not only in one balance sheet.

TSMC’s own roadmap remains a powerful anchor. Lapaas Voice has reported how the TSMC A16 process targets fourth-quarter 2026 production. Each new manufacturing generation creates demand for tools, materials, testing and high-performance systems across the wider ecosystem.

How IPOs can broaden the Taiwan Stock Exchange

The exchange needs more listed companies if it wants the ecosystem story to become investable. Taiwan recorded 70 initial public offerings across the Taiwan Stock Exchange and Taipei Exchange in 2025, according to TWSE executive Brenda Hu. Those deals raised $3.3 billion, a record for the island’s markets, and about 40% of the IPOs came from the AI supply chain.

An IPO gives a private business access to public capital, but it also brings disclosure and governance requirements. For smaller suppliers, listing can fund factories, research and overseas expansion while giving global investors a direct stake in a specialised part of the chain.

Market measure	Reported figure	Why it matters
Taiwan IPOs in 2025	70	Across TWSE and Taipei Exchange
Capital raised	$3.3 billion	Record amount for Taiwan’s markets
AI supply-chain share	40% of IPOs	Shows the breadth of AI-linked issuers
Taiwan Innovation Board	Fewer than 30 companies	Small but designed for priority technology sectors
2026 Taiwan GDP forecast	11.05%	Government forecast revised in August

Taiwan still raises much less through IPOs than Hong Kong. Fortune reported that Hong Kong raised $37.4 billion across 119 deals in 2025. Shanghai’s STAR Market has also attracted prominent technology listings. Lin’s task is therefore not only to find companies; it is to persuade them that Taiwan offers deep capital, international visibility and a suitable valuation.

The Taiwan Innovation Board and hidden champions

The Taiwan Innovation Board, launched in 2021, is central to that effort. It focuses on AI, semiconductors, green energy and other policy-priority industries. TWSE describes it as part of a Taiwan-style “Asian Nasdaq” that can attract high-quality domestic and international companies.

The board remains small, with fewer than 30 listed companies, but Fortune reported that its listed shares had risen 177% in 2026 through the time of the interview. That performance is not a promise of future returns. It does show that investors are willing to reward smaller innovation companies when they can access them.

TWSE has also launched the Taiwan Pristine Stock Index, which deliberately tilts away from electronics and includes biotechnology, construction, food, sports and leisure. The index supports Lin’s “hidden champions” message by creating a product around businesses that might otherwise disappear beneath semiconductor headlines.

Another reform, the “Power Up” programme, asks listed companies to improve governance and explain their medium- and long-term strategies. As of January 2026, almost 46% of TWSE-listed companies had announced plans under the programme. Better disclosure can reduce the information gap facing a fund manager in India, Europe or the Middle East who knows TSMC but not its smaller peers.

Taiwan’s 11% growth forecast strengthens the pitch

Taiwan’s Directorate-General of Budget, Accounting and Statistics forecast on 14 August that real GDP would grow 11.05% in 2026. It estimated second-quarter growth at 12.93% year on year and revised first-quarter growth to 15.43%.

The government linked the strength to AI, high-performance computing and cloud demand. Taiwan’s Ministry of Economic Affairs later reported that July export orders rose 61.9% year on year and manufacturing production increased 26.9%, while warning that geopolitics and trade policy remained risks.

These figures support the “technology island” argument, but they also reveal dependence on a powerful cycle. If global cloud companies slow capital spending, the shock could move through chipmakers, component suppliers and equipment firms together. Diversification across company names does not always mean diversification across economic drivers.

What investors should test before looking beyond TSMC

Investors should start with customer concentration. A small supplier may serve several buyers yet depend on one end market, such as AI servers. Revenue growth can reverse quickly if a large customer delays orders or changes a product design.

Second, they should examine whether technology leadership produces durable margins. Equipment and components can become commoditised, and a company may need heavy research spending simply to keep its position. Cash flow, debt and capital expenditure matter alongside revenue growth.

Third, governance and disclosure deserve close attention. The exchange’s Power Up programme acknowledges that overseas investors need clearer strategy and more comparable information. A compelling ecosystem story cannot replace company-level analysis.

Finally, geopolitical risk affects the whole market. Cross-strait tensions, export controls, currency moves and energy security can change valuations even when a company executes well. TSMC’s overseas expansion reduces some customer risk but also raises costs and forces Taiwan to keep its domestic network competitive.

Why the Taiwan Stock Exchange story matters for India

India’s semiconductor push often focuses on winning a fabrication plant, but Taiwan demonstrates that fabs are only one layer. Design, packaging, testing, materials, equipment servicing, power and skilled labour must develop together. The network produces resilience and makes each new investment more valuable.

Capital markets can reinforce that network by giving specialist suppliers a route to fund expansion. India can study how Taiwan pairs industrial policy with listing platforms, international promotion and disclosure reform. It should also study the concentration risk created when one national champion becomes too large for an index.

The Taiwan Stock Exchange is therefore selling a nuanced proposition. TSMC remains indispensable, but investors should understand the operating system around it. If the exchange can turn that network into visible, well-governed listed companies, Taiwan’s AI boom may create a broader and more durable capital market.
