- Estée Lauder rose 3.5% after fiscal first-quarter results topped expectations and the company raised its full-year outlook.
- Energy stocks fell as oil prices declined, with ExxonMobil, Chevron and Valero all down.
Analyst upgrades and deal headlines drive tech
CrowdStrike climbed 3.4% after Deutsche Bank upgraded the stock to buy from hold. Analyst Brad Zelnick said the market has not yet fully reflected the degree to which AI will broaden the cybersecurity market, a message that appeared to resonate with investors given the sector’s exposure to increased security spend tied to data and automation.
Palo Alto Networks gained 2% in sympathy, reflecting how upgrades in one major cybersecurity name can quickly influence peer sentiment as traders reposition across the group.
Rivian advanced 3.8% following a UBS upgrade to buy. UBS analyst Joseph Spak pointed to the company’s recent sell-off as creating a buying opportunity ahead of what he described as an inflection in the ramp of the R2 midsize SUV. The stock’s move suggests investors were more willing to look past near-term volatility for evidence of production momentum.
In the semiconductor and optical components space, Marvell Technology rose about 3% and Lumentum gained roughly 2% before shares were halted. The move followed an announcement that Marvell agreed to acquire Lumentum in an all-stock transaction valuing Lumentum at $115 billion. The companies said the deal is expected to close in the first half of 2028, leaving investors to weigh strategic fit and integration timeline rather than immediate earnings impact.
Memory rebound points to renewed AI-linked risk-taking
Memory stocks broadly rose after a steep sell-off on Friday, indicating a shift back toward artificial-intelligence-related exposure. Micron, SanDisk and Western Digital each climbed around 2%, as traders appeared to reduce the severity of the prior day’s positioning.
The pre-bell rebound underscores how quickly market participants can rotate within semiconductors when sentiment improves, particularly when moves are tied to expectations for AI-driven demand. While the advance did not change the underlying uncertainty in the cycle, the intraday turn suggested investors were willing to re-enter on weakness.
Corporate results lift consumer discretionary
Estée Lauder rose 3.5% after reporting fiscal first-quarter results that beat analyst expectations and lifting its full-year earnings outlook. The beauty company earned an adjusted 72 cents per share on revenue of $3.72 billion, while analysts surveyed by FactSet expected 51 cents per share on revenue of $3.65 billion.
The combination of a quarterly beat and raised guidance typically supports a re-rating when investors had been looking for evidence that demand and margins can hold up. For shareholders, the key implication was that management’s outlook may reduce concerns about the sustainability of recent performance.
Energy slips as oil declines
Energy shares generally fell as oil prices moved lower at the start of the week. ExxonMobil lost 1.2%, Chevron slipped nearly 1%, and Valero dropped 1.5%.
The moves suggest investors were taking a near-term cue from crude price direction, with upstream and refining names reacting in line with softer commodity sentiment.
Rebound in infrastructure names after Friday’s pullback
Bloom Energy gained 2.3% after plunging 8% in the prior session, indicating a partial reversal as investors returned following the sell-off. Vertiv rose 2.5% after declining 5% on Friday, similarly pointing to bargain-hunting behavior in digital infrastructure and data-center-adjacent exposure.
For these stocks, the pre-bell action appeared more driven by positioning and technical recovery than by a new fundamental catalyst during the session, leaving traders to watch whether the rebound holds as market participants assess the broader growth and margin outlook.
Looking ahead, investors will likely focus on continued signals around AI-driven demand in semiconductors and cybersecurity, as well as the durability of company guidance after earnings. In the near term, oil price direction will remain a key driver for energy stocks, while deal-related questions—such as regulatory prospects and integration plans—may influence Marvell and Lumentum as the transaction progresses toward the expected first-half 2028 close.
