Original: HBM 供不應求 SK 海力士赴美上市獲股東熱烈迴響
SK Hynix told investors its US ADR listing plan—filed confidentially with the SEC in March and targeting up to $14B—has drawn strong demand, with shares up 250% YTD and market cap topping $1T, making it Asia's third trillion-dollar company after TSMC and Samsung. Management said HBM contract pricing negotiations point to memory price strength extending into 2027, with demand still far outstripping supply; Q1 2026 operating profit hit KRW 37.6T (~$25.4B), more than quadrupling YoY.
Why it matters: Concrete capital markets event (up to $14B US ADR listing) plus explicit guidance that HBM tightness and memory pricing extend through 2027—directly stock-moving for SK Hynix and HBM supply chain peers.
Original: 大戶資金正在布局！低位階AI概念股迎接主升段行情
A Taiwanese investment advisory column argues funds are rotating from high-flying AI server/weighted names into lower-valued optical lens plays (Largan 3008, Genius 3406, Ability 3362, Kinko 6209) as AI extends from datacenters into smart glasses, automotive cameras and AI phones. The piece also flags TSMC's (2330) panel-level packaging roadmap with NVIDIA as first customer in 2026, MediaTek's (2454) NVIDIA RTX Spark partnership for Copilot+ PCs and Dimensity Auto traction, plus shipping names Yang Ming (2609) and Wan Hai (2615) benefiting from a SCFI rally (+15.9% over 5 weeks to 2571.73).
Why it matters: Sector rotation commentary with roadmap items (TSMC panel-level packaging, MediaTek-NVIDIA RTX Spark) and shipping freight-rate data — informative supply-chain context but no single stock-moving catalyst, and the piece is a LINE@-promoting advisory column.
Open source articleOriginal: 〈台股開盤〉漲多修正 記憶體與老AI全倒 跌逾1400點摜破4萬5
TAIEX opened sharply lower and fell over 1,400 points to an intraday low of 44,209.53, breaking the 45,000 level and both 5-day and 10-day moving averages on estimated turnover of NT$1.27T (~US$40B). AVGO's guidance triggered AI demand concerns, dragging the SOX down 2.15%; TSMC (2330) slipped 0.63%, while Quanta (2382), MediaTek (2454), Hon Hai (2317), Delta (2308) and ASE (3711) fell over 4%, and memory names Nanya (2408), Winbond (2344) and Transcend (2451) hit limit-down. Only UMC (2303) held gains above 1%.
Why it matters: Broad-based 3%+ index sell-off with named limit-down moves in memory and AI supply-chain names directly held in the TW coverage universe is a clear stock-moving event for PMs.
Original: 黃仁勳下一站韓國行程確定，包含職棒開球與品嘗韓國美食
Nvidia CEO Jensen Huang will arrive in Seoul on the evening of June 4 following his nearly two-week Taipei tour, with plans to meet major Korean tech leaders, throw a ceremonial KBO pitch, and sample Korean cuisine. The visit signals continued engagement with Korea's semiconductor ecosystem, though no specific deals or announcements have been disclosed.
Why it matters: High-profile Nvidia CEO visit to Korea with planned meetings with top tech execs creates HBM/foundry supply-chain sentiment impact, but no specific deals or capex announcements were disclosed.
Open source articleOriginal: 盤中速報 - 集中市場加權指數下跌-1275.23點至44402.23點，跌幅2.79%
Taiwan's TAIEX fell 1,275 points (-2.79%) to 44,402 in early trade on June 5, led by sharp declines in automotive memory and Flash module names. Nanya Tech (2408) hit the -10% daily limit, Winbond (2344) dropped 9.47%, and Macronix (2337) fell 7.99%, signaling a broad memory-sector unwind that has direct read-through to Korean DRAM/NAND peers Samsung and SK Hynix.
Why it matters: Broad memory sell-off with multiple Taiwan DRAM/NAND names at or near daily limit-down is a clear sector-moving signal with direct read-through to Korean memory leaders.
Open source articleOriginal: 盤中速報 - 櫃買市場加權指數下跌-18.94點至421.16點，跌幅4.3%
Taiwan's OTC weighted index fell 18.94 points (-4.3%) to 421.16 in morning trade on June 5, with auto memory (-6.88%) and Flash module (-7.75%) concept stocks leading losses. Nanya Tech (2408-TW) and Apacer (8271-TW) hit the 10% daily limit down, while Winbond (2344-TW -9.47%) and Macronix (2337-TW -7.99%) also slumped — signaling a sharp memory-sector pullback after the index's +59% YTD run.
Why it matters: Sector-wide memory pullback affecting Taiwan memory names not in the tracked universe; signals broader memory sentiment relevant to KR memory peers (Samsung, SK Hynix) but no direct named beneficiary among tracked tickers.
Open source articleOriginal: 盤中速報 - 集中市場加權指數下跌-1398.36點至44279.1點，跌幅3.06%
Taiwan's TAIEX fell 1,398 points (-3.06%) to 44,279 in early trade on June 5, with auto-memory and Flash module concepts leading losses at -6.88% and -7.75% respectively. DRAM maker Nanya (2408-TW) hit limit-down -10%, Winbond (2344-TW) fell 9.47%, and NOR flash specialist Macronix (2337-TW) dropped 7.99% — a sharp memory-sector sell-off after a +57.7% YTD rally that reads across to Korean memory peers Samsung and SK Hynix.
Why it matters: Broad memory-sector limit-down moves in Taiwan (Nanya, Winbond, Macronix all -8% to -10%) are a direct read-across signal for Korean memory peers Samsung Electronics and SK Hynix.
Open source articleOriginal: 盤中速報 - 集中市場加權指數下跌-1185.04點至44492.42點，跌幅2.59%
Taiwan's TAIEX fell 1,185 points (-2.59%) to 44,492 in early trade, with Flash module and automotive memory concepts leading losses. Nanya Tech (2408) and Winbond (2344) hit limit-down or near it (-10%/-9.47%), while Macronix (2337) fell 7.99% — a clear negative read-through for Korean memory peers Samsung and SK Hynix.
Why it matters: Broad memory-sector selloff with named Taiwan memory makers (Nanya, Winbond, Macronix) hitting or nearing limit-down is a clear stock-moving signal for Korean DRAM/NAND peers Samsung and SK Hynix.
Open source articleOriginal: 盤中速報 - 櫃買市場加權指數下跌-17.85點至422.25點，跌幅4.06%
Taipei's OTC weighted index fell 17.85 points (-4.06%) to 422.25 in early trade, with the Flash module concept down 7.75% and auto memory concept down 6.88%. Nanya Tech (2408-TW) and Winbond (2344-TW) hit limit-down or near it, while Macronix (2337-TW) fell 7.99% — a sharp risk-off move in Taiwan memory names that pressures KR memory peers Samsung (005930) and SK hynix (000660).
Why it matters: Broad index/sector move with sharp drops in Taiwan memory names; sentiment read-across for KR memory peers but no single-name catalyst named.

Broadcom fell 12.59% after CEO Hock Tan declined to raise the FY2026 AI chip sales outlook above $100B, dragging Micron down 7.74% and wiping a combined $380.4B in market cap ($286B Broadcom, $94.24B Micron) in a single session — Broadcom's loss ranks as the 4th-largest single-day US wipeout ever. Evercore ISI flagged that MediaTek (2454) is taking custom-chip share from Broadcom on Google work, while Raymond James warned DRAM/NAND ASPs may peak by mid-2026 as CXMT and YMTC ramp, though long-term supply agreements should cushion Micron and by extension Korean memory peers Samsung (005930) and SK Hynix (000660).
Why it matters: Record single-day market cap wipeouts at Broadcom and Micron with named share-shift to MediaTek and explicit memory-cycle peak call directly move HBM/DRAM-exposed Korean and Taiwan names.
