What changed in the AI trade, and why it mattered.
Memory and semicap stocks led a broad-based rally, with semicap now at 100% of names above their 200 EMA.
Semicap strength jumped from 80% to 100% in a week and memory held at 100%, while broad AI infrastructure breadth rose to 72% from 68% — this is a sign the rally is widening into the capital-equipment and memory layers of the supply chain rather than staying concentrated in a few compute names.

Compute breadth cratered from 100% to 78% even as the group posted some of the day's biggest gainers.
Broadcom crossing below its 200 EMA and Qualcomm's cross three days ago pulled compute breadth down sharply despite Marvell's 7% pop, showing dispersion within compute — the group's strength is now driven by fewer names, with Broadcom notably weak just as a story frames Nvidia's Hugging Face deal as a hedge against its custom silicon threat.
Power sector breadth improved to 58% from 42%, with Constellation Energy and Siemens Energy crossing above their 200 EMAs, even as a story questions the durability of the AI power demand narrative in Texas.
Power is a key bottleneck read for AI data center buildout economics; the technical improvement (CEG, ENR.DE crosses) sits in tension with a bearish report claiming Texas cold weather is undercutting the data-center demand story for utilities like CEG, NEE, and SO.
Networking names split sharply: Astera Labs, Coherent, and Corning jumped and Coherent/Corning crossed above their 200 EMAs, while Credo and Ciena crossed below theirs in the prior days.
Networking breadth is stuck at 62%, unchanged on the week, masking a rotation within the group — optics/interconnect winners (ALAB, COHR, GLW) are diverging from names now breaking down technically (CRDO, CIEN), a distinction that matters given the group's role in GPU-to-GPU and rack-to-rack bandwidth for AI clusters.
Neocloud breadth remains split at 50% even as Nebius and CoreWeave both posted strong daily gains.
A story citing Jensen Huang's framing of a 1-gigawatt facility as worth $50-60 billion is circulating as a bullish valuation anchor for neocloud operators like Nebius, but breadth for the two-name group hasn't moved on the week, suggesting the price pop hasn't yet translated into broader technical confirmation.
Dell and HPE reported record AI-driven results but their stocks fell anyway, per today's research feed.
A disconnect between record AI server demand numbers and stock price declines for Dell and HPE is worth flagging as a sentiment/valuation signal separate from the fundamental momentum in server demand — the market may be pricing in something beyond the headline results.
Hyperscaler breadth held flat at 60% ahead of Oracle's earnings report and the upcoming US CPI print.
Oracle reports next week, and the August CPI print lands the day after, framing the September Fed decision that sets the discount rate applied to long-duration AI capex — both are catalysts that could move hyperscaler and broader AI infrastructure valuations without any new data yet.
