Original: 兩岸三地千大企業大洗牌：台灣強勢超車，靠 AI 算力躍升全球第六大資本帝國
Greater China's top 1000 companies' combined market cap doubled in 5 years to NT$677T (~US$21T), with Taiwan's AI infrastructure cluster driving the reshuffle — Delta Electronics' market cap rose 5x in a year and MediaTek added NT$4T (~US$125B) in a single month. TSMC, Aspeed and the broader AI supply chain are forming five prosperity clusters, signaling Taiwan's shift from a single-pillar (TSMC) economy to a full AI infrastructure forest.
Why it matters: Macro/sector reshuffle story citing market-cap rankings and AI supply-chain themes rather than a specific stock-moving catalyst like earnings, capex or contracts.
Original: AI引爆記憶體荒！大記憶體時代來臨，三大關鍵決定誰能吃下紅利
TrendForce sees AI capex diverting ~20% of legacy DRAM/NAND capacity to HBM and DDR5, driving Q1 2026 legacy DRAM contract prices up 93-98% QoQ and Q2 up another 58-63%, with NAND up 70-75% in Q2. Taiwan beneficiaries cited are Nanya Tech (2408), Phison (8299) sitting on NT$72.2B (~$2.3B) of low-cost inventory, and ChipMOS (8150) pushing through back-end price hikes; IDC has cut 2026 PC shipments to 253M units (-11.3% YoY) on cost pass-through.
Why it matters: Sector supply/demand and pricing story citing TrendForce data with named TW beneficiaries, but it's analyst commentary tied to a stock-picking app promo rather than a discrete stock-moving catalyst, and the named Taiwan tickers (2408, 8299, 8150) are outside our tracked universe.
Open source articleOriginal: 台積電(2330)熊本廠首度單季轉虧為盈 Q1 2026淨利達9.5億新台幣
TSMC's Japan subsidiary JASM swung to a quarterly profit of NT$950M (~US$30M) in Q1 2026, its first since production began, versus a NT$9.7B loss for FY2025. The Arizona fab also improved, posting NT$18.8B in Q1 2026 net profit, exceeding the full FY2025 figure of NT$16.1B, signaling that TSMC's overseas fabs are finally scaling toward sustainable profitability.
Why it matters: Confirms TSMC's overseas fab strategy is reaching profitability, a constructive datapoint for the 2330 thesis but not an immediate stock-moving catalyst given the modest absolute numbers.
Original: 黃仁勳出席也沒用，川普證實中國拒買輝達 H200
Trump told Bloomberg that Beijing is refusing to approve Chinese firms' purchases of Nvidia H200 AI chips to force capital toward Huawei and other domestic players, even after Washington cleared Alibaba, Tencent, ByteDance, JD.com and distributors like Foxconn (2317) under a 25% revenue-share framework. Nvidia's $78B annual revenue guide already assumes zero China H200 contribution; analysts had pegged the lost opportunity at $3.5-4.0B/year, with China share collapsing from 95% to near zero.
Why it matters: Sector-level US-China chip trade story; only Foxconn (2317) appears in the tracked universe as a distributor, with no direct earnings catalyst for tracked names.
Open source articleOriginal: 〈熱門股〉訊芯-KY搭CPO熱潮 連拉2根漲停周漲30%創新高
ChipMOS-KY (6451-TW) hit limit-up two sessions running to close at a record NT$577, up 30.84% on the week, as investors bid up CPO (co-packaged optics) plays tied to Broadcom and Hon Hai/Foxconn (2317-TW). Q1 results were weak — revenue NT$1.55B, gross margin 11.96%, operating margin -5.18%, net loss NT$154M (EPS -NT$1.45) — but foreign investors added 1,750 lots and proprietary desks 2,119 lots, signaling the rally is AI-optics-narrative driven rather than fundamentals-led.
Why it matters: Sector/theme story on Taiwan CPO supply chain with Foxconn (2317) ties — no direct catalyst for Korean names and the move is narrative-driven against weak Q1 fundamentals.
Open source articleOriginal: 鴻海法說、MSCI調整台股權重三升、川習會登場 本周大事回顧
Hon Hai (2317) guided Q2 AI rack shipments up high-double-digits QoQ with multi-fold full-year growth and CPO switch mass production in Q3, while Quanta (2382) reaffirmed triple-digit AI server growth and lifted general-server outlook. MSCI's semi-annual review upweighted Taiwan across three indices, raising TSMC (2330) weight and adding MPI (6223), while TSMC also hiked Q1 dividend to a record NT$7/share.
Why it matters: Multiple stock-moving catalysts in one piece: Hon Hai and Quanta AI server guidance, MSCI passive-flow upweight for TSMC, and a TSMC dividend hike.
Open source articleOriginal: 記憶體狂潮讓 SanDisk 股價一年漲 3,600%！但分析師認為「還不算貴」
SanDisk closed at $1,562.34 on May 8, up 3,685% YoY with a $230B market cap, after latest quarterly revenue jumped 250% YoY to $5.95B and adjusted EPS of $23.41 crushed the $14.50 consensus. Samsung sees memory shortage extending into next year and Gartner projects NAND prices up to +234% in 2026; SanDisk trades at ~9.5x P/E vs. SOX average of 25.9x, and is locking in multi-year contracts with minimum revenue, prepayments and third-party financial guarantees — a template Samsung is also adopting, with direct read-through to SK hynix and Samsung NAND.
Why it matters: SanDisk's NAND blowout quarter and 234% NAND price forecast plus the new binding long-term contract template (with prepayments and financial guarantees) directly reprice Korean NAND peers SK hynix and Samsung Electronics.
Open source articleOriginal: 「這不是循環，是時代的革命！」創見董座看 AI：記憶體 30 年規則已遭徹底粉碎
Taiwan DRAM/NAND module makers reported blowout Q1 EPS (ADATA NT$30.5, Team Group NT$27, Transcend NT$18.93, Apacer NT$14.54, Innodisk Feb-Mar combined NT$44.1) as Samsung, SK hynix and Micron divert supply to CSP/GPU customers, pushing other buyers to Taiwan modules. Transcend's chairman calls this a structural AI-era shift (not a cycle), expects shortages through 2028+ as new fab capacity needs 2-3 years, and module makers are raising ~NT$13.2B combined in convertibles/equity to fund inventory; LTAs are only filling ~50% of demand.
Why it matters: Quantified Q1 EPS for multiple listed Taiwan module makers plus named capital raises and an explicit multi-year shortage call from Samsung/SK hynix/Micron supply allocation — directly stock-moving for memory names.
Open source articleOriginal: 群益證美股半導體論壇 看好散熱、傳輸業者主導下一波商機
Capital Securities' US semi forum, citing TSMC's (2330) guidance, argues AI is shifting from cloud to edge and from query to agentic models, driving token consumption and demand for advanced packaging and large-die compute through 2027. The brokerage favors suppliers with patent moats in system-level thermal and high-bandwidth interconnect solutions, while BlackRock flags HBM, optical transceivers, networking gear and OSAT as key beneficiaries.
Why it matters: Broker forum commentary and framework view rather than a stock-moving event, but it explicitly names TSMC and flags HBM/advanced packaging/OSAT supply-chain themes relevant to the tracked universe.
Original: 叩關4萬2屢敗屢戰 外資本周賣超907億元並減碼台積電4.17萬張
Taiex fell 579 points to 41,172 on May 15 as foreign investors net sold NT$10.4B (~US$320M) Friday and NT$90.7B (~US$2.8B) for the week, including 41,700 lots of TSMC. Selling concentrated in active ETFs (00403A active Uni-President Upgrade 50 saw 1.6M lots dumped) and high-dividend products, while foreigners rotated into Innolux, financials, and memory names Powerchip and Winbond. Nanya Tech was trimmed by 24,000 lots, signaling caution on the DRAM laggards.
Why it matters: Broad market fund-flow snapshot with named selling in TSMC and DRAM laggard Nanya Tech, but no fundamental catalyst — sector-flow data rather than a stock-moving event.
