Taiex ends little changed as TSMC's rebound erases earlier losses
Taiwan’s Taiex ended nearly flat, down 0.01% to 45,624.98, after falling more than 600 points earlier. Dealers cited bargain buying led by TSMC, which rose 1.23% to NT$2,470.00. TSMC reported record Q2 net profit of NT$706.56 billion on AI-driven advanced-chip demand. Foreign investors were net sellers of NT$48.33 billion.
How this was made

The 30-second read
Why it matters
TSMC is identified as the primary focus of bargain hunting, with the rebound attributed to expectations for positive guidance and then reinforced by a record quarterly net profit driven by AI-related demand.
Market read
Traders get a same-day read on how TSMC’s AI-driven earnings narrative is being used to stabilize Taiwan’s tech complex after an early selloff.
What to watch
Foreign institutional investors were net sellers of NT$48.33 billion, which could cap follow-through even if TSMC fundamentals look strong.
Background
The Taiex fell sharply in the morning led by semiconductors after overnight declines in U.S. chip stocks, then recovered into the close as investors bought dips.
Ticker impact
Article says TSMC rebounded 1.23% after a dip, with bargain hunting tied to hopes for positive guidance at its investor conference.
Likely supports continued AI-chip demand optimism and reduces downside pressure from the morning selloff.
The text links TSMC’s rebound to investor positioning around guidance expectations and then to a record quarterly net profit driven by AI-related demand.
MediaTek is listed as down 1.07% on the day, reflecting spillover weakness/rotation within Taiwan’s semiconductor complex.
Limited directional edge unless follow-through emerges from AI-demand read-through or sector guidance.
The article provides only the day’s price change for MediaTek, with no separate news or catalyst.
Hon Hai Precision Industry gained 1.46%, showing buying extended beyond pure-play semis into iPhone/AI server supply-chain exposure.
May see incremental support if AI server and smartphone supply-chain sentiment continues to improve.
The article attributes the broader recovery to TSMC and AI enthusiasm, not to any Hon Hai-specific event.
Market effects
TSMC-led AI optimism appears to have pulled the broader Taiwan electronics complex back from morning losses, supporting a semis-focused risk-on bias.
Taiwan’s Taiex recovery is described as partly driven by bargain buying after a morning drop, with reference to Seoul’s rebound.
A strong AI-demand read-through from TSMC can influence global sentiment around advanced chip supply and AI capex expectations.
Counterpoint
The index’s near-flat close may indicate the rebound was tactical bargain hunting rather than a durable re-rating, especially with foreign investors net selling.
