AI-driven optimism kept mega-cap tech in the driver's seat this week, but researchers grew noticeably more cautious on breadth and near-term positioning.
Nvidia remained the anchor bull case, with multiple research notes pointing to 106% YoY revenue growth, triple-digit data center gains, and a projected ~70% revenue jump next fiscal year as evidence the AI capex cycle is real, not a bubble. Constructive calls also emerged on Salesforce (clean beat, undemanding multiple), Meta (litigation overhang lifted), and Marvell. One thread argued the next leg of AI leadership rotates toward hyperscalers — Microsoft, Amazon, Google — as data centers move from build to operate.
The cautionary tone strengthened later in the week: analysts flagged tech, communications, quality and large-cap value as overbought heading into a seasonally weak September, with small caps and the equal-weight S&P signaling narrowing breadth. A contrarian view warned that tech's reliance on OpenAI and Anthropic economics leaves the sector exposed if AI revenue growth disappoints.
In consumer, researchers favored disciplined, premium brands — Amer Sports, On Holding, Estée Lauder — over Nike and Lululemon.
