Week in Review: AI Chip Rotation Crowns New Semiconductor Leaders as Iran

Week in Review

The week of May 3–9 delivered the S&P 500's sixth consecutive weekly gain — the longest winning streak since October 2024 — with SPY adding 2.3% and QQQ climbing 4.5% to record closes. The Nasdaq Composite ended Friday at 26,247, its highest close ever, while the S&P 500 settled at 7,399. Technology led sector performance, with XLK posting a +3.44% Friday session alone as the Philadelphia Semiconductor Index extended its quarter-to-date gain past 50%. Two forces drove the week's narrative: an AI earnings cycle confirming that the capex wave is converting into real revenue, and a geopolitical escalation that moved Iran from a threat environment to confirmed combat in one of the world's most critical shipping corridors.

The dominant equity theme was a semiconductor leadership rotation. Intel's announcement of an Apple manufacturing deal and Micron's 38% weekly surge — driven by AI data center DRAM demand — marked what Wall Street called a "changing of the guard" in the chip cycle. AMD's strong earnings added momentum, confirming that the AI hardware opportunity is broadening beyond Nvidia into memory, foundry, and second-order infrastructure. On the software side, Datadog's +31% single-session surge on blockbuster AI-native monitoring revenue validated that enterprise AI monetization has arrived — revenue growth is no longer hypothetical. The counterpoint came from CoreWeave, whose -10% guidance miss surfaced execution risk in cloud infrastructure buildouts still operating under margin pressure. Of the 440 S&P 500 companies reporting Q1 results, 83% beat estimates, with earnings growth tracking toward +29% year-over-year — largely AI-driven.

Geopolitically, the week escalated in steps. Monday opened with Trump's direct Iran bombing threat; by Thursday, confirmed U.S.-Iran naval exchanges in the Strait of Hormuz moved the conflict from tail risk to operating environment. Gold surged +3.03% on Thursday alone and ended the week near $4,740 per ounce — its highest level since late April — for a weekly gain exceeding 2%, directly validating the war-premium thesis for hard-asset hedges. Friday's April jobs report provided the macro counterweight: 115,000 new payrolls, ahead of consensus, confirming labor-market resilience despite the active geopolitical backdrop and keeping the Federal Reserve firmly on hold. Elsewhere, an AWS data center outage briefly disrupted trading platforms, underscoring single-point infrastructure concentration risk, and Michael Burry's public 1999 bubble comparison added to the ambient late-cycle caution — though VIX closing at 17.19 reflects contained, not elevated, near-term fear.

The weekend overhang is Iran's formal response to a U.S. peace proposal, which Secretary Rubio stated he expected before Friday's close. Markets did not fully price either resolution scenario — a ceasefire acceptance would compress gold's war premium sharply and trigger a risk-on relief rally in energy equities, travel names, and rate-sensitive sectors; a rejection or collapse of talks would deepen Hormuz disruption risk and stress real-economy sectors already showing recession-level guidance. The equity record closes and AI earnings power are real, but they coexist with a geopolitical binary that could reset the risk-reward calculus at Monday's open.

Next Week Outlook

The week of May 11 is the most data-dense of the quarter and arrives with Iran unresolved. Tuesday's April CPI print is the macro pivot: consensus expects headline CPI at +0.7% m/m with the year-over-year rate rising to +3.7% (from +3.3% in March) due to base effects, while core CPI m/m is forecast at a soft +0.1%. A clean or below-consensus print would confirm the tariff-driven inflation pulse is fading and extend the soft-landing narrative that has underpinned six weeks of equity gains; a surprise above +0.7% m/m would reopen the "higher for longer" debate at a moment when geopolitical risk is already elevating the cost of capital for risk assets. The 10-year Note Auction follows Tuesday afternoon (last cleared at 4.28%) — bond market appetite at these yields will signal whether the fiscal-inflation trade-off is being repriced.

Wednesday brings PPI m/m (forecast +0.4%, prior +0.5%) and a 30-Year Bond Auction (prior 4.876%), while Thursday delivers the consumer demand check: Retail Sales m/m is forecast at +1.2% (decelerating from +1.7%) and Core Retail Sales at +1.5% (from +1.9%). A deceleration here would signal the consumer is beginning to absorb tariff pass-through costs and active geopolitical uncertainty — shifting the growth narrative from resilient to fragile without a recession confirmation. Initial Jobless Claims (forecast 209K, prior 200K) will be watched for any early signal that the labor market is losing the momentum demonstrated in Friday's jobs beat. Existing Home Sales on Monday (forecast 3.96M, prior 3.98M) will open the week with a pulse on rate-sensitive demand.

Overhanging all of this is the Iran resolution question. A ceasefire confirmation over the weekend would open the week with a GLD selloff and a broad risk-on rotation into energy equities and consumer discretionary names pricing Hormuz-risk discounts. An absence of resolution keeps oil supply uncertainty elevated and sustains pressure on sectors with Middle East exposure. The AI monetization thesis — confirmed across hardware, software, and memory this week — is durable regardless of geopolitical path, but equity multiples at S&P 7,400 with VIX at 17 leave limited margin for simultaneous data disappointment and diplomatic deterioration. The base case is a week that rewards the CPI softness narrative and buys diplomacy time without a ceasefire — constructive for AI names, neutral for gold, and quietly corrosive for consumer-facing cyclicals.
