Original: 盤中速報 - 集中市場加權指數下跌-822.28點至40350.08點，跌幅2%
The TAIEX fell 822.28 points (-2%) to 40,350.08 in early Taipei trade on May 18, with SDN concept stocks down 6.38% and auto-memory names off 4.07%. Nanya Tech (2408) slid 8.65% leading memory weakness, while networking/SDN losers included Accton (2345) -6.36%; index still up 42.15% YTD.
Why it matters: Broad index sell-off with named sector weakness in auto-memory and SDN affecting tracked TW names, but no single stock-specific catalyst.
Original: 騰落指標創低！AI大洗牌，回檔可留意的AI電力股名單
Citrini Research's 'Supply Chain Inheritance' report argues AI datacenters shifting to 800V DC architectures will drive 1200V SiC demand, projecting AI-related power to be 50% of the SiC market by 2030. The article highlights Taiwan AI power-chain beneficiaries including TSMC (2330), Vanguard (5347), GlobalWafers (6488), and Delta (2308), but frames them as pullback watchlist names rather than immediate buys given stretched breadth indicators.
Why it matters: Sector/supply-chain thesis piece naming multiple Taiwan AI power-chain beneficiaries off a third-party research report, with no company-specific catalyst, earnings, or contract event.
Original: 鎧俠純益估飆增 46 倍、強化與輝達合作 擬赴美上市
Kioxia posted record Jan–Mar 2026 results — consolidated revenue +189% YoY to ¥1.0 trillion and net profit +19x to ¥408B — on surging NAND Flash prices that doubled quarter-on-quarter. For Apr–Jun 2026, management guided net profit of ¥869B (46x growth), more than double the ¥406B street consensus, while flagging an expected supply deficit in 2027 and raising capex ~60% to ¥450B; the company also announced preparations for a U.S. ADS listing and deepened its Nvidia partnership. The NAND pricing rally and demand outlook are a direct positive read-through for Samsung Electronics and SK Hynix.
Why it matters: Kioxia's record earnings, a Q2 guidance beat of more than 2x consensus, a 60% capex increase, and a 2027 supply-deficit call constitute a NAND supercycle confirmation that is directly stock-moving for Samsung Electronics and SK Hynix.
Open source articleOriginal: 韓政府：三星罷工恐釀 100 兆韓圜經損 將強制介入
South Korea's Prime Minister publicly warned the government would invoke emergency labor mediation—a power used only four times since 1963—if Samsung Electronics' union dispute escalates into a strike. Officials estimate one day of semiconductor fab downtime would cost ~$668M in direct losses, with total exposure potentially reaching ~$67B (100 trillion KRW) if production lines must be scrapped and halted for months. Second-round mediation talks resumed Monday at the National Labor Relations Commission after negotiations collapsed last week over performance bonus calculation standards.
Why it matters: Government's first formal threat of emergency mediation combined with officials quantifying a ~$67B worst-case production loss is a direct near-term catalyst for Samsung Electronics (005930) and a potential supply-side tailwind for rival SK Hynix (000660).
Open source articleOriginal: 大尺寸晶片整合趨勢有望為玻璃基板創造長線需求
As chip sizes approach reticle limits, the industry is pursuing chiplet design and advanced 2.5D/3D heterogeneous integration packaging to sustain Moore's Law scaling, creating structural long-term demand for glass substrates. Research firm TRI (Topology Research Institute) projects glass substrate adoption will meaningfully accelerate between H2 2028 and H1 2029. The beneficiaries are advanced packaging houses and foundries with CoWoS-class interposer capabilities.
Why it matters: This is a forward-looking research-report excerpt on glass substrate adoption with a 2028–2029 commercialization horizon — no immediate capex announcement, named contract, or near-term earnings catalyst is present.
Open source articleOriginal: 台灣、南韓成AI熱潮「主要受益者」！高盛：台積電持續支撐台股表現
Goldman Sachs named Korea its highest-conviction Asia market and stayed bullish on Taiwan, citing Samsung, SK Hynix dominance in AI memory and TSMC's lead in advanced chips. KOSPI is up ~80% YTD with Samsung crossing $1T market cap, while TAIEX has gained ~12% in the past month and >40% YTD on TSMC strength.
Why it matters: Broker sector call and macro index commentary rather than a specific stock-moving catalyst, though it names key supply-chain beneficiaries.
Open source articleOriginal: 〈台股盤前要聞〉520行情走味？外資期貨5萬空單罩頂、台積電擬賣世界先進15.2萬張
TSMC (2330) plans to divest up to 152M shares of Vanguard International Semiconductor (5347), about 8.1% of share capital, via block trade to financial institutions, cutting its stake to 19%. Meanwhile foreign net short futures positions on TAIEX have swelled to 50K contracts as traders brace for a near-term pullback, with Nvidia's May 20 earnings flagged as the key catalyst for AI momentum.
Why it matters: Named M&A/divestiture event: TSMC announcing a specific 8.1% block-trade sale of Vanguard is directly stock-moving for both 2330 and 5347.

Taiex fell 431 points last week with foreign investors net short 50,963 futures contracts and net selling NT$90.8B in cash equities, signaling heavy hedging after index highs. Domestic investment trusts countered with a NT$89.8B weekly net buy — the largest since late March 2024 — loading up on UMC (74k lots), Winbond (60k), TSMC (23k), Walsin/Yageo and Nanya Tech, while Nvidia's May 20 earnings is flagged as the pivotal catalyst for AI momentum.
Why it matters: Market-flow and positioning recap with named institutional buying in tracked semi names (TSMC, UMC, Nanya Tech) plus an Nvidia earnings catalyst, but no single stock-moving event.
Open source articleOriginal: 印度晶片夢玩真的！ASML 攜塔塔集團蓋 12 吋晶圓廠
ASML signed an MOU with India's Tata Group to provide lithography support for a 300mm (12-inch) fab in Gujarat, part of Tata's roughly $11B Dholera project targeting auto, smartphone and AI chips. The deal, signed during PM Modi's Netherlands visit, signals India's push to build a domestic semi ecosystem and over time chip away at Taiwan/Korea/China foundry dominance — a long-dated structural headwind for TSMC and Samsung, though near-term production impact is minimal.
Why it matters: Supply-chain/geopolitical story about India's long-term fab ambitions; no near-term capex or order impact on tracked names, though TSMC and Korean foundry peers face a multi-year competitive overhang.

At TSMC's May 14 tech forum, COO Kevin Zhang named smart glasses as AI's most promising edge device, lifting attention on HTC (2498-TW, not in universe) — already shipping VIVE Eagle in Japan via KDDI — and Micro LED leader PlayNitride (6854-TW, not in universe), which built Taiwan's first 4536 PPI color Micro LED glasses on silicon CMOS backplane. The readthrough favors TSMC's advanced-node, high-voltage display and RF platforms as the AI glasses supply chain scales alongside Meta's consumer push.
Why it matters: Roadmap/supply-chain narrative tying TSMC to the emerging AI glasses theme — directional rather than a concrete capex, order, or earnings catalyst.
