⚡ Convergence radar: Sell SMH×3Sell NVDA×3Sell AMD×3

AI chips

The global semiconductor selloff deepened, with Bloomberg and FT anchoring on dual fears: China’s progress in advanced chipmaking and the fragility of “circular” AI funding. SK Hynix alone lost $570 billion in market cap, triggering trading halts in Korea. NVDA, AMD, MU and SMH all fell sharply across Monday’s session — down 2–5% — with the rout spreading from Wall Street to Asia. The speed suggests positioning was overcrowded, with SMH still up 47% YTD despite the week’s 6.1% slide.

SMH

Sell Semiconductors ETF⚡ — Multiple Bloomberg sources confirm broad chip selloff driven by AI spending doubts and China competition; SMH down 6.1% this week but still 47% YTD, signaling crowded positioning.

$548.5 -2.25%
NVDA

Sell Nvidia⚡ — AI bellwether fell 5% last session as doubts over returns from billions in spending grew; forward P/E 15.3x offers little defense if growth estimates slide.

$196.5 -4.99%
AMD

Sell AMD⚡ — Caught in crosshairs of China competition and circular funding fears; -9.1% this week, but 36x forward P/E means it is not yet cheap if AI capex moderates.

$494.9 -5.17%
MU

Sell Micron⚡ — Memory peer to SK Hynix faces same headwinds; 6x forward P/E appears cheap, but earnings momentum is breaking with the Asia-led rout.

$900.2 -2.25%

Asian equities

Asian stocks slid 10% from their June peak, flirting with a technical correction as the chip rout cascaded through Korea, Japan, and across emerging markets. Bloomberg reports forced trading halts in Seoul and deepening selloffs in Tokyo. The move is chip-centric — EWY fell 6.8% this week — but broad-based panic is dragging down EEM and VWO. The outlier: FXI gained last session, hinting that China’s market may decouple on hopes its domestic chip push strengthens in the turmoil.

EWY

Sell South Korea equities — Trading halts and SK Hynix’s collapse signal systemic stress in Korea’s chip-heavy index; EWY down 6.8% this week, with 129% above 52-week low.

$161.2 -1.08%
EWJ

Sell Japan equities — Japan’s chip-linked shares tumble in sympathy; EWJ fell 1.3% this week, and with a trailing P/E of 18.3x, re-rating risk persists.

$91.51 +0.33%
EEM

Sell Emerging markets — Asia-led selloff drags EM broad index; EEM down 2.6% this week, and chip weakness threatens the EM tech supply-chain narrative.

$63.62 +0.46%
VWO

Sell Emerging markets (FTSE) — Slicing of Asia risk hits VWO, though -1.1% weekly move is milder; conviction is lower as China weight may provide a cushion.

$58.23 +0.74%
FXI

Watch China large-cap — FXI gained 2% last session despite Asia-wide selloff — a decoupling signal that may persist if China’s domestic chip push is seen as a winner.

$35.28 +2.02%

Oil

Brent crude plunged 7% after the U.S. and Iran paused Strait of Hormuz strikes, sending USO down 8.7% last session. CoinDesk and Bloomberg both flag the de-escalation as the trigger for a broad risk-on rotation out of energy. Yet the decline only partially unwinds a massive YTD rally — USO is still up 81% — and the geopolitical risk premium hasn’t vanished entirely. Thin liquidity and machine-led trading may have amplified the move, leaving room for a snap-back if tensions reignite.

USO

Sell US Oil Fund — Iran pause triggers sharp reversal; USO -8.7% last session, but YTD still +81% — the geopolitical premium has deflated, not disappeared.

$124.8 -8.73%

Bitcoin

Bitcoin held near $65,000 as the Iran détente lifted risk assets, but the crypto story is split. ETFs posted their third straight week of inflows, yet BlackRock’s IBIT haemorrhaged $415 million in a day, per CoinDesk. The net inflow picture is supportive, but institutional caution is clear. IBIT is down 28% YTD and sits 49% below its 52-week high — a deeply discounted entry if risk appetite returns, but conviction is low given the flow divergence.

IBIT

Watch Bitcoin ETF (BlackRock) — Third weekly inflow overall, but $415M IBIT outflow raises caution; IBIT is -28% YTD and near 52-week lows — potential contrarian long if inflows resume.

$36.77 +1.16%

HY credit

BlackRock dodged a bullet: its $12.55 billion junk-rated bond sale for Meta’s data center rallied in early trading after offering juicy yields. The deal’s success, reported by Bloomberg, suggests the AI infrastructure theme still has legs in credit markets even as equities balk. However, HYG is flat on the week and hugging its 52-week low — one deal doesn’t make a trend, and broader high-yield remains unloved.

HYG

Watch High-yield bonds — AI-related junk deal rallied, but HYG is -1.7% YTD and near 52-week lows — credit resilience in one corner isn’t lifting the whole market.

$79.27 +0.05%

RBA

RBA Governor Bullock concedes the economy is cooling but is unsure rates are high enough to tame inflation, per Bloomberg. The uncertainty leaves the cash rate trajectory open and the Aussie dollar range-bound. EWA has drifted +0.7% this week, but with a trailing P/E of 21.3x, it’s not cheap. No imminent catalyst makes this a hold.

EWA

Watch Australia equities — RBA policy limbo caps near-term direction; EWA up 9% YTD, but P/E 21.3x means little valuation support if hiking fears return.

$28.88 +0.56%

Chip Rout Deepens on China Competition, Circular Funding Fears

The chip rout isn’t just an AI spending scare; Bloomberg identifies two structural threats: China’s quiet advances in advanced chipmaking are eroding the West’s supply-chain edge, while the ‘circular funding’ model—where tech giants invest in AI startups that buy their chips—is starting to fracture. If that circular flow seizes up, AI chip demand could fall faster than any model predicts, turning a sector rotation into a secular unwind.

Our view

The AI chips trade is coming undone, and it’s taking Asia with it. SK Hynix’s $570 billion rout, Korea’s trading halts, and the 10% slide in Asian stocks from June highs aren’t a coincidence—they’re the first dominoes in an overdue re-rating of the AI spending story. NVDA at 15x forward earnings suggests the market is already pricing a growth slowdown, but the real pain is in the memory names where capacity glut fears are acute. Meanwhile, oil’s 8% crash on Iran de-escalation looks like a sideshow; the main event is the unwind of the most crowded trade of 2026.

The bull case argues this is a buying opportunity in a secular trend. NVDA’s forward P/E is not screamingly expensive, and every AI dip over the past two years has been met with fresh retail inflows. The BlackRock Meta bond deal shows institutional money is still pouring into AI infrastructure through credit. If oil stays low, it could lift consumer spending and offset tech weakness. The missing element is earnings—if next week’s reports show data center revenue still accelerating, the chip rout could reverse violently.

Noticeably absent from today’s coverage is any discussion of the dollar or US rates. With stocks wobbling, the 10-year at 4.7% is remarkably steady—no flight to safety, no repricing of Fed cuts. That suggests the bond market sees this as a sector-specific issue, not a macro crisis. Also under-covered: the role of passive flows. ETFs like SMH hold billions in AUM; forced redemptions could amplify the selloff in coming days.

The cleanest second-order trade might be to fade the chip panic by buying quality AI names that got dragged down indiscriminately. NVDA at 15x and MU at 6x are approaching value territory, even if sentiment is awful. The bigger macro expression is to short vol in Asia—the Kospi’s circuit breakers generate headline fear that will likely subside once the initial flush ends. But timing is everything, and the knife is still falling.
