Taipei, Jan 19, 2026, 23:05 GMT+8 — Market closed.
Taiwan Semiconductor Manufacturing Co (2330.TW) shares climbed to a fresh peak in Taipei on Monday, reaching NT$1,780 before settling 1.15% higher at NT$1,760. The gain supported the Taiex index’s record close.
The Taiex closed 230.59 points higher, or 0.73%, at 31,639.29, after hitting a peak of 31,827.39 during the session. Turnover reached NT$799.3 billion ($25.33 billion). Tsai Ming-han, analyst at Cathay Futures Consultant Co, described the early dip and recovery as “a reasonable consolidation” following the recent rally, despite foreign institutional investors offloading NT$28.03 billion in shares.

Why it matters now: TSMC dominates the market. When it hits a new peak, local traders take it as a signal to rally the broader chip sector—and a sign the index could quickly lose ground if sentiment shifts.
The bid isn’t just limited to foundries. Micron Technology announced plans to acquire a Taiwan fabrication plant from Powerchip Semiconductor Manufacturing Corp for $1.8 billion in cash. The move aims to boost DRAM capacity—DRAM being a key memory type used in computers and data centers. The deal is slated to close in Q2 2026, with production expected to start in the latter half of 2027.
NYSE markets in the U.S. remain closed Monday for Martin Luther King Jr. Day, which is dampening cross-border moves for the ADR (TSM). The last trade for the U.S.-listed shares hit $342.40, a gain of 82 cents from the previous close.
TSMC’s push in Taiwan follows shortly after it reported robust demand and outlined 2026 capital expenditures between $52 billion and $56 billion. CEO C.C. Wei hinted the extra land acquisition in Arizona signals more expansive U.S. ambitions.
Records often flip into resistance quickly. Should foreign selling continue, or doubts arise over the staying power of AI-fueled demand, the stock’s rapid climb could hit a wall—and drag the Taiex down alongside it.
Rivals aren’t sitting still. Samsung Electronics and Intel continue pushing for more contract-manufacturing deals, and each fresh capacity announcement can reshape investor expectations on supply tightness and pricing power.
In Tuesday’s session in Taipei, traders will be eyeing if TSMC can stay above NT$1,760 and whether turnover remains close to Monday’s elevated figures. The index continues to rely heavily on the same big-cap stocks.
Chip investors worldwide are also eyeing ASML’s results on Jan. 28, looking for clues on chipmaking-equipment demand and foundry spending.
TSMC’s next key company event is its January monthly sales report, set for Feb. 10. Investors frequently rely on this figure to gauge short-term demand.
