Original: “AI만 믿고 샀는데 어쩌죠”…코스피 뒤집은 반도체 불안 [머니+] - 에너지경제신문
Korean equities reversed sharply as semiconductor stocks led declines, with retail investors who chased the AI rally now facing losses on Samsung Electronics and SK Hynix. The pullback reflects growing concerns about AI capex sustainability and HBM demand visibility into 2H, pressuring index heavyweights.
Why it matters: Sector-wide sentiment commentary on Korean semi names with no specific policy or earnings catalyst, but directly references KOSPI heavyweights Samsung and SK Hynix.
Original: 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: 中 HKC, 세 번째 도전 끝 상장…韓 장비사 수혜 기대
Chinese panel maker HKC finally listed on Shenzhen's main board, earmarking RMB 7.5bn (~KRW 1.4tn) of its RMB 8.5bn raise for next-gen displays — including a Changsha Gen 6 OLED R&D project (RMB 2.5bn), Changsha oxide line (RMB 3bn), and Mianyang miniLED (RMB 2bn). HKC is in talks with KR/overseas OLED tool vendors and is expected to announce its Gen 6 OLED capex plan as early as 3Q with vendor selection by year-end; named potential beneficiaries include KC Tech (281820), plus non-universe names DMS, Invenia, Narae Nanotech, KMAC, Sunic System and ICD. HKC is also weighing a no-cut deposition scheme (full-mother-glass) and considering reuse of ex-JDI Gen 6 tools alongside new orders, with FMM vs eLEAP both on the table.
Why it matters: Credible TheElec scoop on a concrete RMB 7.5bn Chinese display capex pipeline with named KR equipment beneficiaries, but only KC Tech sits in our tracked universe; most named winners (DMS, Invenia, Narae, Sunic, ICD) are small-caps outside coverage, capping ticker-level read-through.
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: OpenAI牵手博通，亮出首款自研AI芯片 - 新浪网
Chinese media highlights OpenAI's partnership with Broadcom to launch its first self-developed AI chip, framing it as another major hyperscaler diversifying away from Nvidia's GPU monopoly. The move expands Broadcom's custom ASIC pipeline alongside Google TPU and Meta MTIA, and pressures Nvidia's long-term share of training/inference silicon; TSMC remains the manufacturing beneficiary as the likely foundry.
Why it matters: OpenAI's custom ASIC with Broadcom is a direct structural threat to Nvidia's hyperscaler GPU demand and a clear tailwind for Broadcom and TSMC as ASIC partner and foundry.
Open source articleOriginal: Anthropic进一步抢占OpenAI市场份额：付费收入和用户持续增长
Chinese media (36Kr) highlights an Indagari credit-card-transaction report showing Anthropic's Claude has grown paid-subscriber revenue ~75% since January 2026, eroding OpenAI's lead, with DataCamp noting Claude has overtaken 'AI' as its most-searched term. The framing underscores intensifying US AI-model competition — a demand-signal positive for AI infra suppliers (Nvidia GPUs, hyperscaler capex at AWS/Google/Microsoft hosting Anthropic) rather than a direct China-substitution story.
Why it matters: Not a China semi story, but accelerating Anthropic compute demand reinforces hyperscaler AI capex and GPU pull-through for tracked names.
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.
Original: 股王信驊除息秀被打趴倒地 千金股8檔跟摔跌停 僅南電逆勢漲停
Stock king Aspeed (5274) was slammed to limit-down on its ex-dividend day despite a record NT$81 dividend (up 55% YoY), dragging 8 four-digit-priced Taiwan names including MediaTek (2454), GlobalWafers (6488), Unimicron (3037) and Yageo (2327) down with it. Nan Ya PCB (8046) was the lone gainer, hitting limit-up against the tape as heavy ex-dividend selling and broad electronics weakness swept the market.
Why it matters: Broad sector-wide price action driven by ex-dividend selling rather than a fundamental catalyst, but covers multiple tracked TW semi names including MediaTek and GlobalWafers.
