Taiwan Semiconductor Now 45% of Taiex as Shares Climb 30%
Taiwan Semiconductor's shares have risen about 30% this year to a new 52-week high near $389, with the company now representing roughly 45% of Taiwan's Taiex index. A $2.77 billion one-day foreign buying spree underscores investor confidence in its central role in the AI supply chain.
1. Geopolitical Supply Chain Risks
Taiwan Semiconductor's advanced semiconductor output is concentrated on an island where any disruption in exports could severely constrain global AI and cloud computing hardware availability. Estimates warn that a blockade of Taiwan might slash U.S. economic output by 11% and China’s by 16%, underscoring the company's critical position.
2. Surge in Foreign Investment
Overseas investors funneled a record $2.77 billion into Taiwan equities in a single session, marking the largest net foreign buying since 2005 and fueling further gains in chip-related names. Market participants view Taiwan Semiconductor as a cornerstone of the AI hardware supply chain, driving sustained inflows.
3. Dominance in Benchmark and Price Performance
The company's weight in the Taiex index has grown to approximately 45%, up from about 15% a decade ago, reflecting its market leadership. Shares have climbed roughly 30% year-to-date to a new 52-week high near $389, emphasizing strong investor confidence.
