Executive Summary

Semiconductor stocks rose more than 2% Friday, led by Teradyne, KLA Tencor, and Monolithic Power, but the group remains down double digits for the quarter versus a 15% gain for the software-focused IGV ETF. Traders on the desk were split on direction, but Tim Seymour argued semis are "breaking higher" given no letting-up in AI CapEx — Wall Street projects $1.3 trillion in hyperscaler capital spending next year. Steve Grasso favored the SMH ETF over the SOX index given its heavier Nvidia and Micron weighting, positioning those names as the largest beneficiaries of rising capex.

  • Semis up >2% Friday; SOX index down double digits this quarter vs. +15% for software's IGV

  • Tim Seymour: no letup expected in AI CapEx heading into the Trump-Xi summit; $1.3 trillion in hyperscaler capex projected for next year

  • Steve Grasso prefers SMH (22% Nvidia weight, 5% Micron) over SOX (9%/9%) given capex flows benefiting Nvidia and Micron disproportionately

  • Nebius (neocloud) raised compute rental prices roughly 20% this week, seen as evidence of durable pricing power for legacy chip capacity

  • Healthcare up almost 2% since Monday; Moderna, Dexcom, Thermo Fisher among top gainers

3. Novo Nordisk Investor Day Looms as Stock Lags Peers

  • NVO: Novo Nordisk — -15% YTD — Investor day Monday; street wants business-development clarity beyond Wegovy

  • MRK: Merck — +40% YTD — Re-rated on aggressive BD deals, moved past Keytruda patent-cliff fears

  • Jared Holt: Novo likely to look for acquisitions outside metabolic/obesity given competitive gap to Lilly

  • GLP-1 drug prices have fallen from roughly $1,200/month to $300-400/month, pressuring the "consumer product" framing even as volumes remain strong

4. Apple iPhone 18 Pro Launch: Strong Demand, Stretched Valuation

  • iPhone 18 Pro/Pro Max on sale Friday, the first major product launch under CEO John Ternus

  • Apple up 24% YTD, best-performing Mag 7 name, trading around 35x forward earnings

  • Julie Biel: "uncomfortably expensive" at current price despite genuine interest in the device lineup

  • Confirmed attendees at Thursday's state dinner include Nvidia's Jensen Huang, OpenAI's Sam Altman, JPMorgan's Jamie Dimon, and Citigroup's Jane Fraser

1. Semis-vs-Software Rotation Reaches an Inflection

The desk's split on whether semis are "breaking higher" or "breaking down" reflects a broader market debate also visible on Bloomberg Tech and CNBC Closing Bell the same day: whether 1H 2026's software outperformance was a temporary overcorrection or a durable structural shift away from picks-and-shovels AI plays.

2. GLP-1 Trade Has Bifurcated Beyond Novo/Lilly

The panel's observation that Merck — not a pure-play obesity name — is the year's best pharma performer suggests investors have rotated away from framing GLP-1 exposure as a two-horse race, rewarding business-development agility instead.

3. Mega-Cap Valuation Discomfort Persists Despite Bullish Consensus

Even traders constructive on Apple's long-term "owns the customer" thesis flagged 35x forward earnings as stretched, echoing a recurring theme across today's shows: strong fundamentals coexisting with valuation anxiety at the index's largest constituents.

4. AI Pacing Concerns Are Bleeding Into Capital Markets Timing

Anthropic's IPO delay, alongside SoftBank's leveraged OpenAI financing reported elsewhere today, shows the AI-safety debate is starting to directly affect deal and listing timelines, not just sentiment. ---

Sentiment Analysis

Overall Market Sentiment: Cautiously Constructive

GLP-1 pricing degradation: Continued price erosion ($1,200 to $300-400/month) threatens the consumer-health investment thesis.
