🔎 The Week That Was

Wall Street closed out the week on an absolute tear, with the S&P 500 finishing at 7,398.93 — up 2.75% — and the Nasdaq leading the charge at 26,247.08, good for a 4.70% weekly gain. If you only looked at the headline numbers, you'd think it was a solid week. Look under the hood, and it was something else entirely.

The story of the week was technology, full stop. The sector ripped 8.31% — not a typo — while everything else played supporting roles at best. Consumer Discretionary and Materials managed modest gains of 2.11% and 1.86%, respectively, but the real action was concentrated in a handful of chip and AI names that went absolutely vertical. When one sector moves that much in five trading days, you're not watching a broad rally — you're watching a rotation.

The flipside of that rotation was ugly in spots. Energy cratered 6.21% and Utilities shed 3.56%, suggesting investors were actively pulling money out of defensive and commodity-linked plays to fund their tech positions. Financials and Healthcare also closed in the red, which is worth watching — those sectors tend to signal broader economic sentiment, and the weakness there deserves some attention heading into next week.

As markets reopen Monday, the central question is whether tech's monster week was a one-time catalyst trade or the start of a sustained re-rating. With the Dow sitting just under 50,000 at 49,609.16 and the Russell 2000 up 2.33%, breadth was decent but not spectacular. The setup heading into the week is interesting — momentum is strong, but sector divergence this sharp rarely sustains itself without a reality check somewhere along the way.

📈 What Drove the Moves

The chip trade was the only trade this week, and the numbers are genuinely staggering. Datadog led all gainers at +36.45%, closing at $200.16, while AMD surged 33.28% to $455.19 and Intel — yes, Intel — rocketed 30.42% to $124.92. Micron added 29.55% to reach $746.81, and Super Micro Computer closed out the top five with a 26.68% gain. When you see moves like this clustered in semiconductors and AI infrastructure names, it almost always traces back to either a major earnings beat, a macro catalyst around AI spending, or both. This week, the market appears to be pricing in a significant acceleration in AI infrastructure demand, with these names acting as the clearest beneficiaries.

On the other side of the ledger, Shopify had a rough week, dropping 13.44% to $110.41, with Cloudflare close behind at -12.51% to $196.13. Roblox fell 11.90%, and PayPal slid nearly 10% to $45.37. It's notable that some of these — Cloudflare especially — are tech-adjacent names that in another week might have ridden the sector tailwind. Instead, they got sold, which suggests investors weren't buying tech broadly; they were making very specific bets on the AI hardware stack and rotating out of software and consumer-facing platforms. Exxon's 5.93% drop to $144.57 fits neatly into the energy sector's broader -6.21% weekly decline, likely pressured by oil market concerns flagged by Aramco's CEO around the potential loss of 1 billion barrels and what that signals for demand recovery.

📅 Earnings: Week Ahead

🔭 What to Watch This Week

Three names are worth putting on your radar before markets reopen. Rivian reports Tuesday with a consensus estimate of -$0.64 per share — the EV maker is still burning cash, and what Wall Street really wants to hear is any update on production ramp, margin trajectory, and the ongoing Amazon delivery van relationship. Given how brutally the market has treated EV names that miss on delivery guidance, this one carries real downside risk if the numbers disappoint.

Also reporting Tuesday is Unity Software, where the Street is looking for $0.21 per share. Unity has been through an extended period of restructuring and leadership transition, so the earnings number almost matters less than the forward commentary — specifically, whether the company's ad platform and runtime fee changes are actually sticking with developers. Any sign that the business model reset is gaining traction could be a meaningful positive catalyst.

Cisco rounds out the week on Wednesday with a $0.86 EPS estimate, and this one carries some macro weight beyond just the company itself. Cisco's enterprise networking and security spending data acts as a proxy for corporate IT budgets broadly. In a week where the market clearly rewarded AI infrastructure hardware, Cisco's commentary on enterprise demand — and whether AI-driven network upgrades are translating into real orders — could set the tone for how investors think about the next leg of the tech trade.
