The S&P 500 closed at 7,543.64, up 0.81% and back within shouting distance of its record highs after Wednesday's ceasefire-collapse scare knocked the index down to 7,482.71. The index opened defensively as overnight headlines showed the U.S. hitting Iranian targets for a second straight day, but buyers stepped in by mid-morning as AI-hardware demand chatter around SK Hynix's Friday U.S. ADR debut — reportedly more than 7x oversubscribed — pulled the semiconductor complex sharply higher. The Nasdaq Composite was the day's leadership index, up 1.30% to 26,206.89, powered almost entirely by chip and optical-communication names rather than the mega-cap software cohort, which lagged (GOOG -1.7%, MSFT -0.7%).
The Dow lagged its peers, adding just 0.27% to 52,487.41 as cyclical and staples weight — Boeing, American Express, and a soft PepsiCo print — offset the index's tech-adjacent components. The Russell 2000 tracked the broader risk-on tape well, up 1.29% to roughly 2,994.5, a signal that this wasn't purely a mega-cap AI trade — small caps participated in the rebound in step with the Nasdaq for the first time in several sessions.
Session character was a clean V: soft open on Iran headline risk, steady grind higher from mid-morning through the close as chip strength broadened out, with the tape finishing near session highs. Breadth improved materially from Wednesday's ugly 3.5-to-1 decliners-over-advancers skew on the NYSE, flipping to a roughly 2-to-1 advancer lead by the close as the rally broadened beyond just semis into industrials and financials late in the day.
Advancers led decliners by roughly 2-to-1 on the NYSE, a sharp reversal from Wednesday's 3.5-to-1 negative skew. Volume ran close to the 20-day average, with participation broadening out from the semis-led open into a fuller risk-on tape by the final hour.
VIX commentary: The VIX eased back to the 16 handle, down from Wednesday's 16.90 close, as vol sellers returned alongside the equity rally. Term structure normalized modestly but stayed elevated versus pre-Iran-escalation levels — options desks aren't fully discounting the tail risk of another headline flare-up over the weekend.

"Chips did the heavy lifting today — the rest of the tape just came along for the ride. Tomorrow's SK Hynix debut tells us how much gas is left in that tank."
Technology was the day's engine, but it was a narrow, hardware-specific rally rather than a broad tech bid. Lumentum (+12.1%), Corning (+7.4%), Marvell (+6.9%) and Coherent (+5.1%) all ripped on optical/AI-infrastructure demand read-throughs tied to the SK Hynix offering, while Palantir (-4.0%) extended its 29% year-to-date slide and mega-cap software names like Microsoft (-0.7%) and Alphabet (-1.7%) sat out the move entirely. That divergence — hardware up, software down — is the single most important cross-current in today's tape and argues this is a targeted supply-chain trade, not a re-rating of the whole AI complex.
Industrials and Consumer Staples were the session's laggards even as the index rallied. Boeing (-3.0%) and PepsiCo (-3.0%, missing EPS by a penny on weaker U.S. consumer spending tied to higher gas prices) both weighed, a reminder that the domestic consumer and industrial cyclicals remain fragile heading into the back half of earnings season. Energy gave back Wednesday's spike as WTI slipped back under $73 once the immediate Strait-of-Hormuz supply scare eased, even as ConocoPhillips and Marathon Petroleum held onto modest gains on refining-margin strength.
Lumentum ran on heavy volume as optical-networking names caught a bid tied to AI-infrastructure buildout chatter and the pending SK Hynix U.S. ADR listing, which is reportedly more than 7x oversubscribed. The move puts LITE among the best-performing large-cap tech names of the week and reinforces the read-through that memory/optical supply constraints remain the binding bottleneck in the AI buildout, not GPU demand itself.
PepsiCo unofficially kicked off the earnings season with adjusted EPS of $2.20, missing the $2.21 consensus by a penny, on revenue up 6.4% year-over-year to $24.18B. Management flagged softer U.S. consumer spending tied to higher gas prices and broader macro volatility — a data point staples and consumer-facing desks should watch closely heading into the rest of earnings season.
Palantir extended its 29% year-to-date decline, continuing to unwind some of its extreme 2025 valuation multiple even as the broader AI-hardware trade ripped higher around it. The divergence between PLTR's software-multiple unwind and the hardware/semis rally is the clearest signal that this is a rotation within AI, not a wholesale de-risking of the theme.
Custom-silicon and optical-component names moved as a bloc on demand commentary tied to the AI-infrastructure buildout and the SK Hynix offering. Analyst upgrades across the semiconductor complex accompanied the move, and the group's strength was broad enough to offset a soft day for mega-cap software and search names.
Boeing and American Express were among the Dow's weakest components, dragging the index's gain down to a fraction of the Nasdaq's. Neither move was tied to a specific headline catalyst today, and the weakness reads more as a rotation out of cyclicals and into the AI-hardware trade than as a standalone fundamental story.
Quiet after-hours tape — no S&P 500 constituents reported earnings after today's close. The next scheduled catalyst is SK Hynix's U.S. ADR debut Friday, which the memory/semis complex will trade around from the open. Watch for secondary moves in MU, MRVL, and the broader SOXX complex on the listing.
Crude's reversal was the key cross-asset tell today: WTI slipped back under $73 a barrel as the immediate Strait-of-Hormuz supply-disruption scare eased, even with U.S.-Iran hostilities technically still live. That gave equities room to rally without a rates or inflation-expectations headwind — the 10-year barely budged at 4.58%, and the dollar softened slightly as the safe-haven bid from Wednesday partially unwound. If oil reverses higher again on fresh escalation, today's equity gains get a lot harder to hold.
The tape shook off Wednesday's ceasefire-collapse scare and closed firm, with the Nasdaq and Russell up roughly 1.3% each as chip and optical names did essentially all of the work. The most important development wasn't the index gain itself but the composition beneath it: this was a narrow, semis-and-optics-led rally with mega-cap software and cyclicals like Boeing and Amex left behind, which tells us the AI trade is rotating rather than broadening. Tomorrow's binary catalyst is the SK Hynix U.S. ADR debut — an over-7x-oversubscribed listing that will set the tone for the memory/semis complex — set against a still-live Iran-Israel backdrop that kept the VIX from fully round-tripping Wednesday's spike. Stay long the AI-hardware trade into the SK Hynix listing, but keep hedges on for cyclicals and staples, and don't fade the VIX cushion — this de-escalation could reverse on a single weekend headline.
