Meta's new 'Meta Compute' program—renting surplus AI capacity to third parties—lifted Meta shares 8.81% but triggered broad selloffs in semiconductor and AI cloud stocks on fears that hyperscaler demand may be peaking. The author rebuts the concern, citing compute intensity curves (reasoning AI = 10× base, agentic AI = 100×, physical AI = 1M×) and Morgan Stanley's estimate that Meta's rental revenue adds at most ~$3 to 2028 EPS versus a 2026 Q1 EPS of $10.44, implying the pivot is capacity optimization, not a structural capex retreat. Pullbacks ahead of TSMC's mid-July analyst call and late-July US mega-cap earnings are framed as buying opportunities across the TSMC and HPC supply chains, including 2330, 2454, 3711, 6223, 3037, 8046, 2308, and 2383.

Why it matters: The piece is analyst newsletter commentary layered on a real Meta catalyst, providing demand-signal context and named supply-chain buy ideas, but contains no primary corporate disclosure, contract, or earnings data of its own.

The TAIEX surged ~950 points intraday but closed up only 428 points at 44,999, with NT$997.5B (~US$30B) in volume falling below the NT$1T threshold needed to confirm genuine buying, signaling price-volume divergence. Margin-financing maintenance ratios must retreat to ~155% before a clean bottom is confirmed, implying ~2,000 additional index points of downside risk; TSMC (2330) is propping the index while most stocks remain under heavy selling pressure. ABF substrate equipment lead times are lengthening, delaying capacity expansions and extending supply tightness—a potential pricing tailwind that keeps Unimicron (3037) on the sector watchlist.

Why it matters: Market technical commentary with a concrete ABF substrate supply-chain signal (longer equipment lead times delaying capacity expansion, extending pricing power), but no discrete stock-moving event such as earnings, capex announcement, or contract news.

Taiwan's TAIEX dropped 1,683 points (-3.64%) to 44,571, breaking the 45,000 level on roughly NT$1.5T turnover as foreign investors aggressively unloaded ahead of TSMC's (2330) July 16 earnings call. The OTC index fell 5.59% with sharper damage to small/mid-caps, while ABF substrate names including Unimicron (3037) showed relative resilience as analysts frame the selloff as margin-call washout rather than trend reversal.

Why it matters: Broad market commentary tied to a TSMC earnings preview and ABF substrate sector view rather than a specific stock-moving catalyst.

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.

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.

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.

Taiwan's TAIEX fell 1,057 points to 46,043 on three sentiment shocks: Korea's unrealized capital gains tax proposal, SK Hynix pacing HBM4 capacity (sending Micron down 13%+), and BofA's call for further Fed hikes. The analyst frames the drop as a healthy shakeout — May export orders hit a record $89.48B (+47.2% YoY, 16th straight month of growth) and NA hyperscaler capex is projected at $805B in 2026 and $1.1T+ in 2027, keeping foundry, advanced packaging, ASIC, CPO and ABF substrate names as core beneficiaries.

Why it matters: Macro/sector commentary citing real capex and order data plus a specific HBM4 pacing claim affecting SK Hynix and Micron, but the piece is an analyst market wrap with a promotional tail rather than a stock-moving disclosure.

Taiwan's TAIEX reversed from a 48,000 intraday high to close down 640 points on NT$1.6T turnover, with TSMC (2330) also turning lower as chase-buying interest hit a monthly low. Korea's KOSPI plunged over 8% intraday triggering a circuit breaker, while power-management plays Chipmos-KY (6525) and Episil (3707) bucked the selloff to lock limit-up; ABF substrate leader Unimicron (3037) gave back early gains.

Why it matters: Broad market selloff commentary with sector rotation observations on power semis and ABF substrates, not a single stock-moving catalyst — typical analyst-promo daily wrap.

Atreides Management's Gavin Baker told TBPN that the AI bottleneck trade — chasing chokepoint suppliers like DRAM makers — is approaching its end, and pointed to Ajinomoto refusing to hike ABF substrate material prices despite surging AI demand as evidence. Nitto Boseki similarly said it has no plan to raise T-glass or low-Dk glass prices, instead lifting its FY2024-27 capex plan 50% to ¥120B (from ¥80B) to expand supply and defend share.

Why it matters: Sector-level call on the AI supply-chain trade with concrete pricing/capex datapoints from Ajinomoto and Nitto Boseki — affects DRAM and ABF substrate names but not a specific stock-moving catalyst for any single ticker.

TrendForce highlights a shift from training to inference as the AI compute battleground, citing NVIDIA's $20B Groq IP/team acquisition (Dec 2025), Taalas HC1 hitting 16,960 tokens/s/user on Llama 3.1 8B at ~1/5 the per-million-token cost of NVIDIA B200, and Cerebras's May 2026 IPO. Hard-coded inference ASICs that bake model weights into Mask ROM with on-chip SRAM threaten the HBM-heavy GPU architecture, pressuring HBM demand assumptions and reshaping the inference silicon supply chain.

Why it matters: Sector-level roadmap and architecture-shift commentary from TrendForce with implications for HBM demand and GPU/ASIC supply chain, but no named TW/KR ticker action or capex figure.

Taiwan is reportedly considering its own export controls on AI chips bound for China to mirror US restrictions, a move that would formalize Taipei's alignment with Washington's tech-containment strategy. If enacted, the rules would directly bind TSMC and Taiwanese ASIC/packaging suppliers, closing gray-channel routes that have let some China-bound AI silicon ship from Taiwan.

Why it matters: A Taiwan-level export control regime aligned with US BIS rules would be a first-order policy shift for TSMC and the broader Taiwan AI supply chain, directly affecting China-exposed revenue.

TAIEX fell over 500 points (1.13%) at the open to 46,364, dragged by TSMC slipping below NT$2,400 (low NT$2,385) ahead of its AGM, with Hon Hai (2317) down 1.62% and IC substrate trio Kinsus (3189), Unimicron (3037) and Nan Ya PCB (8046) leading declines (Kinsus -4.47%). Foreign investors net bought NT$51.6B yesterday and flipped slightly long in futures; Uniseec advises buying dips in large-cap AI weighted names while flagging high US-Iran tension risk.

Why it matters: Daily market-open recap with broker commentary and sector rotation color around TSMC's AGM — moves named stocks but no new stock-specific catalyst.
