• TSMC's shares surged 49% in 2026 (up to 26 May), driven by demand for AI semiconductors used in data centers, graphics processing, and machine learning.
• TSMC accounts for more than 42% of Taiwan's benchmark index, making the market highly concentrated in this company.
• Taiwan’s financial regulator raised the ceiling for domestic funds to invest in a single stock to 25% of net assets in April 2026, up from 10%, potentially influencing larger domestic allocations towards TSMC.
• India’s market capitalization declined due to record foreign portfolio outflows in 2026, attributed to elevated valuations, a weakening rupee, rising energy costs, and slower corporate earnings growth.

Background & Context

Taiwan’s rise as the fifth-largest stock market is primarily due to its dominant technology sector, especially the semiconductor industry embodied by TSMC, the world's largest contract chipmaker. The recent boom in artificial intelligence technology has increased global demand for specialized semiconductors, driving TSMC’s stock rally. Taiwan’s market is notably concentrated, with TSMC constituting over 42% of the benchmark index.

India’s stock market trajectory in 2026 has been negatively impacted by significant foreign portfolio outflows, influenced by its elevated market valuations, depreciation of the Indian rupee, surging global energy prices (partly due to geopolitical tensions affecting oil supply), and a slowdown in corporate earnings growth.

Regulatory changes in Taiwan increased domestic funds’ allowable investment in single stocks, specifically benefiting highly weighted stocks like TSMC and possibly attracting over US$6 billion in inflows, further boosting Taiwan’s market capitalization.

Why This Matters for Exams / Exam Relevance

This development illustrates key contemporary global economic trends such as the impact of technology sector growth (particularly semiconductors and AI technologies) on stock market valuations, shifts in international investment flows, and the importance of geopolitical and macroeconomic factors on emerging and developed markets. Understanding these trends and their influence on major economies like Taiwan and India is valuable for current affairs, economics, and finance-related competitive exams.
