Original: 【盤後贏指標】台股史上第三大跌點，這次不是單純回檔？！
TAIEX plunged 1,683 points (its 3rd-largest point drop ever) to close at 44,571, breaching both MA5 and MA20 as the Win Indicator flagged a 2nd consecutive day of breakdown below the 47,443 strong/weak pivot. Semiconductors led the rout with NT$338.6B (~US$10.4B) net outflow and a 5.16% sector drop, followed by optoelectronics (-NT$86.3B, -4.18%) and electronic components (-NT$76.7B, -3.58%), signaling systemic de-risking across the entire electronics supply chain rather than an isolated pullback.
Why it matters: Broad TAIEX selloff and electronics-wide outflow data is meaningful sector/market context but lacks named-stock catalysts; it's market commentary tied to a proprietary indicator rather than a specific corporate event.
Original: 傳 OpenAI 擬延後 IPO，AI 概念股賣壓湧現鎧俠挫 12%
Kioxia fell 12% after the NYT reported OpenAI is weighing pushing its IPO into next year at a $1T valuation target, triggering a broad AI-concept selloff. The former Toshiba Memory unit had become the Nikkei 225's largest market-cap name on AI memory demand; it also flagged a stock split and a US ADR listing targeted for early next fiscal year (April-June).
Why it matters: Sector-wide AI memory sentiment shock driven by an unconfirmed OpenAI IPO timing report — directly readable into Korean NAND/HBM peers but not a company-specific catalyst for them.
Open source articleOriginal: 趁你病，要你命！SK 海力士直接開挖三星系統與晶圓代工牆角
SK Hynix has opened mid-level hires for HBM Foundry PI and HBM digital design roles whose requirements closely match Samsung's System LSI and foundry engineers, amid Samsung internal unrest over bonus gaps (memory staff get ~6x base salary vs ~2x for non-memory). Analysts warn talent outflow could undermine Samsung's HBM4 progress, which has relied on cross-divisional collaboration between memory, foundry and System LSI.
Why it matters: Personnel/competitive-dynamics story between SK Hynix and Samsung with potential HBM4 roadmap implications, but no immediate capex, contract, or earnings catalyst.
Open source articleOriginal: 台股重挫近 1,700 點創史上第三，股王股后同步跌停，台積電、鴻海都難逃下跌
Taiwan's TAIEX plunged 1,683.5 points (closing at 44,571.76) on Friday with record turnover of NT$1.54T, the third-largest single-day drop ever, triggered by a >1% drop in TSMC ADRs and weakness across Asian markets. TSMC (2330) fell 2.09% to NT$2,340 losing its monthly line, while MediaTek (2454) and Yageo hit limit-down; Hon Hai (2317), Delta and UMC dropped 3-8%, and memory/silicon wafer/silicon photonics/passive component names led the broad-based panic selling.
Why it matters: Broad market sell-off with named price moves on key TW semi/EMS heavyweights — useful tape context for TW-exposed PMs but a single-session market event without new fundamental catalyst.
Original: 〈訊芯股東會〉蔣尚義：鴻海集團有FOPLP經驗 訊芯將共同掌握玻璃基板商機
At its shareholder meeting, Foxconn-affiliated OSAT Sigurd (6451-TW) chairman Chiang Shang-yi said glass substrates remain in early-stage development but the Foxconn (2317-TW) group's existing FOPLP experience positions it to capture the opportunity once the trend solidifies, likely in 3-4 years. Near term, glass will stay as a carrier in advanced packaging rather than a true substrate, and Sigurd will monitor rather than commit heavy capex prematurely.
Why it matters: Roadmap commentary on glass substrate timing and Foxconn group's FOPLP positioning — supply-chain signal but no concrete capex or contract.
Open source articleOriginal: 大摩預估 AMD Venice 出貨量將超車輝達 Vera，台積電成最大贏家
Morgan Stanley projects AMD's next-gen EPYC Venice (Zen 6, TSMC 2nm) shipments will jump from 1.25M units in 2026 to 6.75M in 2027, exceeding NVIDIA Vera's estimated 5.75M units. Both CPUs lean on TSMC advanced packaging (CoWoS-L for NVIDIA AI GPUs, CoWoS-R for Vera), with TSMC monthly wafer capacity expected to reach ~200K in 2027 as agentic AI drives sustained compute demand.
Why it matters: Specific Morgan Stanley unit-volume forecasts for 2027 with named beneficiary (TSMC advanced packaging capacity to ~200K wpm) constitute a stock-moving sell-side roadmap call.
Open source articleOriginal: 〈台股盤後〉史上第三大跌點1683點摜破4萬5 周線翻黑跌1893點
TAIEX plunged 3.65% (1,683.5 pts) to 44,571.76, the third-largest point drop in history, with weekly losses of 1,893 pts (-4.07%) as Nasdaq futures fell 500+ pts and Asian peers tumbled (Nikkei -5%, KOSPI intraday -9% on memory rout). TSMC fell 2% to NT$2,340, MediaTek hit limit-down at NT$3,880 after Qualcomm's data center push, Delta -9%, and passives/PCB/substrate names (Yageo, Walsin Tech, Unimicron, etc.) were broadly limit-down or sharply lower; only Nan Ya PCB bucked the trend +8%.
Why it matters: Third-largest point drop in TAIEX history with named limit-down moves in MediaTek and Yageo, plus a Qualcomm data-center catalyst directly hitting MediaTek — clear stock-moving event across tracked TW names and KR memory read-across.
Original: 台股總市值蒸發5.5兆元跌破150兆元 權值股重災區 聯發科、國巨收跌停
The TAIEX fell 1,683 points (-3.64%) on June 26, the third-largest point drop in history, erasing nearly NT$5.5T (~US$170B) in market cap and pushing total market value below NT$150T. AI-related heavyweights led the rout: MediaTek (2454) and Yageo (2327) hit limit-down on Qualcomm AI ASIC competition fears and quarter-end window dressing, while Delta (2308), UMC (2303), Auras (3017) and Wiwynn (6669) all fell more than 8% as foreign investors extended June net selling to over NT$450B.
Why it matters: Broad market sell-off with named heavyweight movers and a specific competitive catalyst (Qualcomm AI ASIC threat to MediaTek), but no single company-level event — sector/market-data story rather than a stock-moving fundamental change.
Original: 韓股震盪免驚 大摩：今年最高上看 1 萬 2,500 點
JP Morgan reiterated Overweight on Korean equities and raised its base-case KOSPI target to 12,500 (from 9,000), with a bull case of 15,000 and bear case of 8,000, framing the recent foreign-led pullback as a buying opportunity. The bank cites an AI 'winner-takes-all' dynamic benefiting Samsung Electronics and SK hynix, while Morgan Stanley separately sees KOSPI potentially testing 10,500 on still-tight memory/AI supply.
Why it matters: Top-down sell-side target hike on KOSPI with explicit positive call on Samsung and SK hynix as AI memory winners — moves sentiment but is not a company-specific catalyst.
Open source articleOriginal: 高通攜手 Meta 強勢進軍 ASIC 市場，市場憂心分食聯發科商機股價打入跌停
Qualcomm announced a multi-generational strategic partnership with Meta to supply its Dragonfly C1000 data-center CPU starting H2 2028, formally entering the AI ASIC custom-silicon market. MediaTek (2454) fell limit-down -NT$430 to NT$3,880 on fears of share loss in AI ASIC, despite recently winning Google's next-gen TPU order from Broadcom and European brokers raising its target price to NT$6,500; CEO Rick Tsai still targets 10-15% of a $70-80B AI ASIC TAM by 2027.
Why it matters: Stock-moving event: MediaTek hit limit-down on a named competitive threat (Qualcomm-Meta multi-generational ASIC/CPU deal), with explicit price action and analyst target references.
