Taiex Hits New Closing High Amid Volatility; 49 Stocks Join 'Thousand-Dollar' Club

Electronic Technology · Semiconductors · economic_daily · 2026-09-22

The Taiex reached a record intraday high before retreating, yet managed to close at a new peak as high-priced stocks dominated market activity.

What Happened

Record-Breaking Volatility: Driven by positive momentum from U.S. markets, the Taiex hit an intraday record of 48,601.53 points. However, profit-taking ahead of the Mid-Autumn Festival holiday led to significant volatility, with the index closing at a record 47,800.17 points.

High-Value Stock Dominance: While TSMC saw a slight decline, other heavyweights like MediaTek and Hon Hai performed well. The market's highlight was the surge in high-priced stocks, with 49 companies now trading above NT$1,000, led by strong gains in ASPEED and Alchip.

Sector-Specific News: AUO saw its stock hit the daily limit for two consecutive days following reports of a potential advanced packaging partnership with Intel. Conversely, the Formosa Plastics Group stocks faced downward pressure due to falling international oil prices.

Market Outlook: Analysts note that while the market remains strong, the lack of significant volume expansion suggests a cautious approach ahead of the holiday. The market is expected to remain in a consolidation phase, with investors closely watching for future volume trends.
