Taiwan's weighted index (TAIEX) closed at 46,331.45 points, up 356.23 points, moving above the 46,000 markCITE:E1CITE:E10. TSMC closed at NT$2,420, up NT$10 or 0.41%, with turnover in the stock reaching NT$32.763 billion (327.63億元)CITE:E3CITE:E16.
NVIDIA's quarterly earnings and forward guidance beat market expectations, sending its own stock up 8.74%CITE:E6. That move fed through to Taiwan's electronics-heavy market at the open: TAIEX opened up 95.61 points at 46,070.83, led by TSMC, UMC, MediaTek and Nanya Technology among the early gainersCITE:E8. CNA reported that NVIDIA's results drove TAIEX as much as 600 points higher in the morning sessionCITE:E6.
TAIEX climbed as high as 46,574 points intraday, a gain of 599 points from the prior closeCITE:E7CITE:E9. That level took the index past the previous swing high of 46,402 points, which had been set on August 14CITE:E7.
Turnover for the session came to roughly NT$1.023 trillion (新台幣1兆230億元), matching a separately reported figure of NT$1.02 trillionCITE:E2CITE:E10. That volume accompanied the index's move from an opening gain of 95.61 points to a closing gain of 356.23 pointsCITE:E8CITE:E1.
Thirty-six listed stocks, including UMC, locked at their daily limit as TAIEX closed up 356.23 pointsCITE:E11. UMC itself closed at its limit price of NT$130, with same-day turnover of NT$40.956 billion (409.56億元), the fourth-highest turnover of the sessionCITE:E15.
MediaTek, Delta Electronics, Yageo and Largan Precision all posted gains alongside TSMC. The table below ranks the ten stocks with the highest turnover on August 28.

MediaTek closed at NT$3,985, up NT$120 or 3.10%CITE:E4. Delta Electronics closed at NT$1,830, up NT$60 or 3.39%, with turnover of NT$22.776 billionCITE:E5CITE:E20.

Five of the ten highest-turnover stocks fell even as the index climbed: Nan Ya Plastics, Nanya Technology, Unimicron, Winbond and WIN Semiconductors. Nan Ya Plastics closed at NT$220.5, down NT$7, on turnover of NT$43.206 billion, the second-highest of the sessionCITE:E13. Nanya Technology closed at NT$540, down NT$1, with turnover of NT$41.417 billionCITE:E14. Unimicron closed at NT$1,110, down NT$70, with turnover of NT$31.645 billionCITE:E18.

TAIEX's move past its August 14 high of 46,402 points to an intraday 46,574 and a close of 46,331.45 was accompanied by both large turnover (NT$1.023 trillion) and broad-based limit-up activity (36 stocks)CITE:E7CITE:E9CITE:E1CITE:E10CITE:E11. Yet within the day's ten highest-turnover names, the gains concentrated in chip- and component-linked stocks — TSMC, UMC, MediaTek, Delta Electronics, Yageo and Largan Precision — while Nan Ya Plastics, Nanya Technology, Unimicron, Winbond and WIN Semiconductors, all among the top ten by turnover, closed lowerCITE:E12CITE:E13CITE:E14CITE:E15CITE:E16CITE:E17CITE:E18CITE:E19CITE:E20CITE:E21.

The headline numbers — a 356.23-point gain, NT$1.023 trillion in turnover, and 36 stocks locked at their daily limit — describe a broad-based session, but the turnover-leader table tells a narrower story. Among the ten stocks with the highest turnover, the winners were concentrated in chip and component names tied to the NVIDIA earnings spillover (TSMC, UMC, MediaTek, Delta Electronics, Yageo, Largan Precision), while Nan Ya Plastics, Nanya Technology, Unimicron, Winbond and WIN Semiconductors — all still among the day's top ten by turnover — closed lower. That split matters more than the index print itself: high volume with limit-ups shows participation, but participation and direction aren't the same thing when five of the ten most-traded names moved against the tape. The metric worth watching next session is whether Nan Ya Plastics, Nanya Technology, Winbond and WIN Semiconductors stay near the top of the turnover ranking while still declining, or whether flows rotate back into them — that would tell us if the NVIDIA-driven move was a broad re-rating or a narrow, chip-specific spillover.
SK Hynix (SK海力士) is planning a ₩10 trillion plant investment in Japan, a move that coincided with gains in two Japan-focused semiconductor ETFs. The plan follows a first half of 2025 in which the company posted ₩39.87 trillion in revenue, ₩15.10 trillion in net profit, and a debt-to-equity ratio that fell to 48.13% from 62.15% at the end of 2024.
US Commerce Secretary Howard Lutnick is pushing a new round of semiconductor tariffs that would tie tariff-free import quotas to how much chip manufacturing a company commits to build inside the United States, a design that could extend duties beyond the advanced processors already taxed since January 2026 to AI servers, laptops and gaming consoles.
Four hyperscalers are on track to spend roughly $725 billion combined on AI infrastructure in 2026, up about 77% from 2025's $410 billion, and NVIDIA's data center revenue confirms real near-term demand with 117% year-over-year growth. Yet Bain projects an $800 billion annual revenue shortfall by 2030, Michael Burry alleges $176 billion in understated depreciation, and circular deals linking NVIDIA, OpenAI, and Oracle draw dot-com comparisons — even as NVIDIA and JPMorgan Asset Management reject the bubble framing.
