Executive Summary
The TAIEX advanced roughly 2.3% over the full trading week of July 20-24, 2026, finishing at 43,654.84. The path featured a steep Monday recovery attempt, a record single-day point gain on Tuesday, further upside through mid-week, and a notable decline on Friday.
The weekly close reflected resilience in technology-related names despite broader market volatility and foreign investor net selling.
Weekly Drivers
- A record 1,783-point single-day gain on July 21 was led by TSMC and AI-related stocks.
- Global tech sentiment and semiconductor demand provided support mid-week.
- Foreign investors recorded net sales of NT$47.06 billion over the five sessions.
- Average daily turnover rose to NT$1,121 billion.
- Position limit adjustments for TAIEX futures took effect mid-month, with limited immediate impact noted.
Sectors & Breadth
Electronics and technology services sectors led advances for the week, consistent with the outsized moves in semiconductor names. Other sectors showed more muted participation, suggesting relatively narrow breadth during the rebound.
The index's intraday range exceeded 2,900 points across the week, highlighting concentrated flows into select large-cap technology issues rather than broad market participation.
What to Watch
- Upcoming global semiconductor earnings and supply-chain updates.
- Taiwan central bank policy signals and cross-strait developments.
- Foreign institutional positioning data for the week ahead.
- U.S. tech sector performance and its spillover to Taiwan equities.
Capital-Flow Context
Foreign investors were net sellers of NT$47.06 billion during the week even as the index posted gains, pointing to potential profit-taking or rebalancing amid elevated valuations in technology names. Domestic institutional and retail flows appear to have absorbed the selling pressure.
Currency effects remained secondary, with the New Taiwan dollar showing limited movement against the U.S. dollar over the period. Passive inflows tied to index-tracking products continued to provide a structural bid, though active foreign positioning turned cautious.
