Moore Securities analyst frames Tuesday's plunge as leverage-driven washout (margin + credit + mortgage + pledged-stock loans) rather than a top, arguing AI capex remains in 'explosive growth' mode per Nvidia. Names four pullback buys tied to TSMC fab build-out and AI infra: Marketech (6196, orders visible to 2028), Channel Well (3032, CSP-certified liquid cooling), WIN Semi (3105, GaAs + LEO satellite + 1.6T optical PD), and Jentech (4989, RTF copper foil for AI servers).

Why it matters: Analyst-driven pick list with supporting operational data points (orders to 2028 at 6196, 48.9% YoY April sales at 3105) rather than a market-moving corporate event; touches TSMC supply chain tangentially.

Nvidia AI server partner Wiwynn (6669-TW) warned that AI data center supply chain bottlenecks are spreading beyond memory chips to networking and other critical components, with shortages potentially extending through 2028 and pushing global AI infrastructure costs higher. Taiwan futures night session surged over 1,000 points to 44,894 after the cash market fell 1.4% to 43,636, with foreign investors net selling NT$38.6B but accumulating memory names PSMC, Macronix and Nanya Tech.

Why it matters: Wiwynn, a key Nvidia AI server ODM, explicitly flagging multi-year networking chip shortages is a concrete supply-chain signal affecting AI infrastructure capex and component pricing through 2028.

Nvidia AI server partner Wiwynn (6669-TW) says supply shortages have spread beyond memory chips to networking ICs and other key components, with tight conditions likely lasting until late 2027 or 2028. Chair Emily Hong sees datacenter hardware demand strong for 3-5 years driven by Meta and Microsoft capex; over 80% of revenue comes from US customers and Wiwynn plans 3 new US plants on top of its newly operational El Paso, Texas facility, with possible GDR/convertible bond raises in 2027 beyond the $2B convertible issued in March.

Why it matters: Named Nvidia AI server ODM warns of multi-year supply shortages extending beyond HBM to networking chips, with concrete US capex expansion and fundraising plans that directly affect AI hardware pricing and the broader Taiwan ODM/Korean memory complex.

NVIDIA CEO Jensen Huang said Huawei's newly proposed 'Tao Law' — which uses 3D stacking, advanced packaging, and hybrid bonding to boost transistor density without EUV — is a genuine breakthrough but poses no threat to TSMC, which has been developing die stacking, 3D packaging, and hybrid bonding for nearly a decade. He emphasized that TSMC's CoWoS and SoIC capabilities remain critical to NVIDIA Blackwell/Rubin, AMD, and Apple, reinforcing TSMC's advanced packaging moat amid China's non-scaling workaround strategy under US sanctions.

Why it matters: CEO commentary reaffirming TSMC's advanced packaging lead over Huawei's non-EUV roadmap is a sentiment/positioning story rather than a discrete catalyst, but it directly frames the competitive moat for TSMC and the CoWoS supply chain.

FactSet's latest poll of 22 analysts raised Wiwynn's 2026 EPS consensus to NT$344.78 from NT$340.85 (range NT$312.88–385.48), with a consensus target price of NT$6,500. The upward revision reinforces the AI server ODM's earnings momentum heading into 2026 and is a positive read-through for the broader Taiwan AI server supply chain.

Why it matters: Consensus EPS revision is incremental (~1%) rather than a discrete catalyst, but it confirms positive AI server earnings momentum relevant to the supply chain.

Powertech Technology (6239-TW) reported April net profit of NT$883M (~US$28M), up 183% YoY, with EPS of NT$0.95 and revenue of NT$7.58B, a 3-year-10-month high. Management guides sequential quarterly improvement on memory/logic ASP hikes, with FOPLP yield at 95% and shipments for AMD's next-gen Venice CPU starting 1H 2027, marking the industry's first 2.5D panel-level packaging in volume.

Why it matters: Solid earnings beat and FOPLP mass-production milestone for AMD are meaningful OSAT data points, but Powertech is not in the tracked TW/KR universe and the read-through to listed names is indirect.

MiTAC (3706-TW) said at its earnings call that all product lines—compute, network, and storage racks—are showing growth momentum on sustained AI and data-center demand, with H2 expected to outpace H1 and full-year revenue growth 'beyond doubt.' The company is shifting from ODM/motherboard/bareboard work toward full systems, racks, clusters, and total solutions; Vietnam's Hanoi plant entered mass production in Q2, two new US plants begin operating in Q3 (gated by power and liquid-cooling buildout), and Mexico expansion continues.

Why it matters: AI server ODM capacity update and guidance tone is supply-chain relevant but MiTAC is not in the tracked universe and no specific customer or order figure was disclosed.

Foreign investors flipped to net sellers of NT$38.6B (~US$1.2B) on Taiwan's bourse as the TAIEX fell 1.4% to 43,636 on record turnover of NT$1.59T. They dumped 289K lots of Innolux but kept aggressively buying memory names — 121K lots of PSMC (6-day cumulative 424K), 82K lots of Macronix and 62K lots of Nanya Tech — alongside smaller buys in Hon Hai (2317) and Inventec (2356).

Why it matters: Daily foreign flow data showing rotation from panels into Taiwan memory names — sector signal relevant to KR memory peers but not a single-name catalyst.

TAIEX fell 620.36 points to 43,636.44 on heavy volume of NT$1.59T (~$49B) after Iran-US tensions flared, despite hitting an intraday record 44,954. TSMC (2330) briefly topped NT$2,360 with market cap above NT$61T (~$1.9T) before closing down NT$5; memory names Nanya (2408) and Macronix (2337) rallied on HBM/AI storage demand ahead of COMPUTEX. Pegatron chairman dismissed AI bubble concerns, citing TAIEX PE of 22-28x as not overheated.

Why it matters: Broad market-data and sector commentary piece covering index moves, COMPUTEX positioning, and individual momentum picks; no single stock-moving catalyst for tracked names, though TSMC's record and AI/HBM read-through are relevant.
