A one-day reversal that gave back most of the records.
Friday’s session was the cleanest risk-off day since the Iran war began. The S&P lost 1.24% to 7,408.50, the Nasdaq 1.54% to 26,225.14, the Dow 1.07% to 49,526.17 — back below 50,000 within 24 hours of recapturing it. The selling concentrated in the AI/chip complex (Cerebras −10%, Micron −6.6%, Intel −6%, AMD −5.7%, NVDA −4.4%) and the picks-and-shovels names AMAT, LRCX, and KLAC gave back too, despite AMAT’s beat-and-raise. The macro catalyst was Trump’s escalation toward Iran — Brent jumped 3.10% to $109.26, WTI 3.55% to $105.42, and the Strait of Hormuz is now characterised as effectively closed under a dual blockade. The VIX spiked 22.4% to 17.36; yields backed up across the curve. Weekly, the S&P and Nasdaq still finished +0.3%; the Dow eked −0.05%.

The macro turned. The complex turned with it.
Friday’s session ran in the opposite direction from every framing the week had set up. The S&P lost 1.24% to 7,408.50, giving back roughly two-thirds of the week’s gains in a single afternoon; the Nasdaq did worse at −1.54%; the Dow fell 1.07% to 49,526.17, surrendering the 50,000 level it had reclaimed only 24 hours earlier. The Russell 2000 dropped 1.66% — the breadth signal the Lens had flagged Friday morning ran in the wrong direction. The single mechanical explanation is the chip complex: Cerebras at −10% was the deepest move; Micron −6.6%, Intel −6%, AMD −5.7%, NVDA −4.4% paced the broader-zone selling. AMAT, fresh off Thursday-evening’s beat-and-raise, gave back 3.2% into the close — its premarket gap-up evaporated by noon as the macro turned and positioning unwound.
The macro catalyst was Trump’s escalation toward Iran — a pivot from Tuesday’s “massive life support” framing toward direct, escalatory rhetoric, with the Strait of Hormuz now characterised as effectively closed under a dual blockade. Brent jumped 3.10% to $109.26, WTI 3.55% to $105.42; the VIX spiked 22.4% to 17.36, the largest one-day vol move since the war began. Yields backed up across the curve (10-year +5 bps to 4.54%, 30-year +5 bps to 5.11%); the dollar firmed; BTC gave back below 83K. The Fed-chair handover itself became a footnote: Powell technically remains Chair pro tempore through the weekend pending final White House signatures on Warsh’s paperwork. The first FOMC under Warsh is still scheduled 16–17 June. Weekly, the records pile still stands — S&P +0.3%, Nasdaq +0.3% — but the bid that built it is now demonstrably positioning-driven, not flow-driven.
Risk-off across the board; oil and vol took the bid.
Every major equity index red; yields backed up modestly on the oil bid pulling inflation expectations higher; the dollar firmed with yields; the VIX spiked 22% — the largest one-day vol move since the Iran war began. The single cleanest cross-asset read is Brent +3.10% on a day the S&P fell 1.24% — that’s a textbook macro risk-off, not a single-name story.

Chart of the Day
What happens when you sell a beat-and-raise.
Friday's single-day percentage move for ten benchmark AI/semiconductor names. Six of ten finished worse than −5%; Cerebras led the drawdown at −10%, memory and x86 names paced the high-conviction selling, and the cap-equipment names — including AMAT, which had beat-and-raised after Thursday's close — gave back along with the rest. The bid that built into Thursday's three records came undone in a single session as Trump escalated the Iran framing and Brent jumped 3%.

Trump escalates; Hormuz now characterised as effectively closed
President Trump pivoted Friday from Tuesday's "massive life support" framing toward direct escalatory rhetoric on Iran, saying he was "losing patience" with the lack of diplomatic progress. The Strait of Hormuz is now treated as effectively closed under a dual blockade — the central obstacle in ongoing negotiations. Brent jumped +3.10% to $109.26; WTI +3.55% to $105.42. The Vault Hormuz indicator upgrades from RESTRICTED to CLOSED.

Chip complex sold off — even AMAT's beat-and-raise
The week's standout earnings print got sold. AMAT closed −3.2% Friday despite Thursday-evening's $7.91B revenue beat, $8.95B Q3 guide, and +30% calendar-2026 industry growth call. Cerebras −10%, Micron −6.6%, Intel −6%, AMD −5.7%, NVDA −4.4% paced the broader-zone selling. Sell-side maintained a "Buy" stance through the move — Stifel, UBS, RBC, Evercore, Bernstein and BofA all raised AMAT price targets despite the price action.

Fed
Powell stays Chair pro tempore through the weekend
Jerome Powell's four-year term as Chair formally ended Friday, but Kevin Warsh was not sworn in as expected — final White House paperwork is still pending. The Fed named Powell Chair pro tempore until Warsh takes office, an unusual procedural wrinkle that keeps continuity in place over the weekend. The market will read whether Warsh's first day is Monday or pushes further; the first FOMC under his chairmanship is still 16–17 June.

Energy names bid hard; the rate trade reversed.
The mirror image of Thursday played out across GCC on Friday afternoon. With Brent +3% and the Hormuz indicator upgrading to CLOSED, the energy complex took the bid that had been absent for two weeks: Aramco +2.3%, ADNOC +1.9%, regional E&P names broadly +1.5–2.5%. DFM and ADX banks gave back as the duration-risk premium re-priced higher with US yields — UAE 10-year eurobond spreads widened back 4 bps, Saudi 5-yr CDS up 3 bps. The two-sub-trade construction the Vault desk has been running flipped cleanly: long oil-linked equities outperformed by ~3 percentage points; the rate-sensitive bank book lagged.
For clients reviewing positioning into Vol. 10, the asymmetric exposure now is on the Hormuz side: with the indicator CLOSED and Brent trading $109 with positive carry, the marginal news flow is more likely to push toward de-escalation than further escalation (the ceasefire has already broken multiple times this cycle). The cleanest hedge against a Monday gap-down in oil is the topside skew Vault flagged at the start of the month; for the energy-linked equity book, partial profit-takes into Sunday-night futures are the prudent move. Trump’s pivot Friday afternoon was significant — but reversible.

CLOSED · dual blockade · Trump escalation
Three reads into the weekend.
A risk-off Friday on a Trump-Iran pivot doesn’t invalidate the records week — but it does say the bid was positioning-driven. The weekly scorecard still finishes positive; the question is whether Vol. 10 opens with continuation of the reversal or a tactical buy on Monday morning.
Trade 01
The Friday selling was positioning, not flow
A −1.54% Nasdaq day with the AI/chip complex concentrated in the selling — and AMAT's beat-and-raise getting given back into the close — is a positioning unwind, not a fundamental re-rate. The names that had run hardest into Thursday's records (Cerebras, Micron, AMD, Intel) gave back hardest. The marginal buyer of Thursday's session was already long the AMAT print; when the macro turned, that buyer flipped to seller. The fundamental call on cap-equipment growth (AMAT's +30% calendar-2026 guide) is unchanged.
Trade 02
The Hormuz indicator is now the cleanest read
The pivot from RESTRICTED to CLOSED is a one-step escalation on a four-step scale (OPEN → DEGRADED → RESTRICTED → CLOSED → SUSPENDED). The mechanical impact is asymmetric: Brent has positive carry above $105, the topside skew is bid, and the marginal news flow over the weekend (G7 statement on diplomacy, US carrier movements, Iranian state TV signalling) skews toward de-escalation now that it has escalated. Long oil-linked equities + topside Brent vol is the cleanest carry into Vol. 10.
Trade 03
Warsh's swearing-in delay is not nothing
The "Chair pro tempore" wrinkle is a procedural quirk on its face, but it's also a market test: the same Senate that confirmed Warsh 54–45 just delayed his actual swearing-in by 48–72 hours. The market will read whether Monday opens with Powell still atop the institution or with Warsh formally sworn. Either way, the first FOMC under Warsh is still 16–17 June; rate vol stays bid through it. The G7 statement Sunday night is the most important headline of the weekend.
