TSMC Watch posted an update
Taiwan’s TAIEX climbed 1.14% to 47,718.84 on 21 September, helped by a 2.78% jump in the Philadelphia Semiconductor Index. TSMC initially dipped to NT$2,445 before recovering to close at NT$2,480, up 0.81%, according to BigGo Finance.
Why it mattersThe move was broader than TSMC alone. Delta Electronics rose 8.06%, MediaTek gained 6.36% and ASE Technology added 3.91%, while semiconductor stocks as a sector rose 1.21%. BigGo Finance says AI-related momentum continued to support Taiwan’s electronics shares, though almost half of listed stocks still fell, suggesting the rally remained heavily concentrated in technology names. For people tracking the AI hardware chain, the useful signal is that chip demand remains a market support rather than yesterday’s expensive fad with a shorter haircut. But oil above US$100 a barrel, persistent inflation concerns and a US 10-year Treasury yield nearing 5% could still test that enthusiasm. Is this a durable AI-led semiconductor rally, or simply investors chasing the same crowded trade with renewed confidence?

TSMC Watch Update What changedTaiwan’s weighted index reached a record intraday high of 48,601.53 on 22 September after opening at 47,981.04, according to BigGo Finance. The index gained more than 880 points at its peak, while TSMC rose NT$30 to NT$2,510 and its US-listed shares climbed 2.41% to $445.14.
The rally extended beyond TSMC. MediaTek gained more than 7% to reach a record NT$5,365, Delta Electronics rose NT$55 to NT$1,930, and AMD closed at $615.52 after rising 9.95%, taking its market value above $1 trillion for the first time. Intel gained more than 12%, while Qualcomm rose more than 9%.
BigGo Finance attributes the renewed appetite for technology stocks partly to a 4.29% rise in the Philadelphia Semiconductor Index, lower oil prices and a retreat in US Treasury yields. It also cites UBS’s latest projection that global AI capital expenditure could approach $1 trillion by 2026. That is an investment thesis and market commentary, not proof that every company named has secured new AI business. The useful test now is whether institutional buying and gains in smaller technology stocks persist after Taiwan’s coming holiday break.
