CNBC Closing Bell
2026-10-13 · Hosted by Scott Wapner, Melissa Lee, Michael Santoli · CNBC
Executive Summary
Stocks closed mostly lower Monday as the market marked the four-year anniversary of the bull run (S&P 500 up nearly 120%, Nasdaq up more than 160% since October 12, 2022). Tech led declines after high-beta AI names sold off: memory stocks like Micron and SK Hynix fell 3-6% on news of a new Chinese chip design from Shanghai-based CXMT, and optical names like Coherent and Ciena dropped sharply in sympathy. Microsoft unveiled its third-generation Maya AI chip, closing within a couple dollars of its all-time high and reclaiming the $4 trillion market cap level.
Key Stories & Changes
1. Four-Year Bull Market Anniversary
S&P 500 up nearly 120% and Nasdaq up more than 160% since the October 12, 2022 closing lows
S&P 500 up nearly 14% year-to-date, but more than four in 10 stocks in the index are lower for the year
HSBC's Max Kettner: multiple compression from higher yields has already been "quite clear," setting up favorable risk-reward into earnings season
2. Microsoft's Maya AI Chip Reduces Nvidia Reliance
Microsoft unveiled its third-generation Maya 300 chips, claiming up to 7x more AI tokens per data center rack versus its predecessor
Stock closed within a couple dollars of its all-time high, regaining the $4 trillion market cap
Evercore estimates homegrown chips could be ~10% of Microsoft's AI chip spending by early next year; production begins in 2027
Microsoft will continue using Nvidia and AMD chips for model training
3. Memory & Optical Stocks Sell Off on Chinese Competition
MU: Micron — -3% to -6% — Pressured by China's CXMT new chip design
SK Hynix: SK Hynix — -3% to -6% — Same Chinese competitive pressure
NVDA: Nvidia — -1.3% — Broader AI chip weakness
Coherent/Ciena: Optical names — Sharply lower — Sympathy sell-off extending beyond memory into optical tech
ANET: Arista Networks — Price target cut $525→$475 (Wells Fargo) — Cybersecurity/networking-adjacent weakness
4. Software: Salesforce Upgraded, Adobe Downgraded
Salesforce: double-upgraded to Buy at Bank of America, price target raised $160→$285; BofA's Tal Liani cited a "comprehensive" AI offering across all four stack layers, though growth timing remains uncertain
Salesforce stock down 12% YTD but up 40% in the past three months
Adobe: double-downgraded to Underweight at Wells Fargo, price target cut to $225 (below the $238 close); cited weak Q3 results, 2027 guidance concerns, a new CEO, and a risky shift to a freemium model
Analyst framed Salesforce/ServiceNow as benefiting from AI as a "tailwind," Adobe facing it as a "headwind"
5. Meta's Muse Wonder Model Launch
Meta shares rose 3% on the debut of Muse Wonder and a higher-end Muse Wonder Full, built for law, finance, and health use cases
Available to Muse/Muse Code subscribers paying $20/month or more
Meta's Muse app downloaded 8.8 million times since early September launch, up from 5 million at end of September
6. Energy Hits Record High
The XLE energy ETF hit an all-time intraday high as Brent crude topped $106/barrel
Driven by weekend attacks in the Middle East and an unconfirmed Trump-announced Russia-Ukraine "energy ceasefire" that did not hold
Trump defended allowing Russia to sell diesel to global markets amid bipartisan criticism
7. Bank Earnings Setup
JPMorgan, Citigroup, Wells Fargo, Goldman Sachs report starting Tuesday
Barclays' Jason Goldberg: loan and deposit levels at record highs, net interest margins holding, credit quality "very benign"
Concerns include rising unrealized bond-portfolio losses from higher rates and AI-agent-driven deposit flight risk, though "certainly not in the near term"
Citigroup flagged as cheapest among top-10 banks by valuation with room to re-rate
8. eBay Named Top Pick
Morgan Stanley raised eBay price target to $132 (from $127), implying ~18% upside
Analyst compared eBay to "the NYSE for used items," with live commerce now driving ~40% of GMV growth
eBay was among the S&P 500's best performers on the day
Trends Identified
1. Bifurcated Market Beneath Index Highs
While headline indices sit near record highs, breadth remains weak: banks and semis are both in double-digit percentage corrections from their highs, and over half of S&P 500 constituents sit 20%+ below all-time highs. This sets up earnings season as a referendum on whether laggard sectors can "catch up" or whether mega-cap concentration persists.
2. AI as Both Tailwind and Headwind for Software
The Salesforce/Adobe divergence crystallizes a broader software-sector split: companies seen building AI into a comprehensive platform (Salesforce, ServiceNow) are rewarded, while those seen as vulnerable to AI-native disruption or facing execution risk (Adobe) are punished, even before hard revenue evidence of AI impact materializes either way.
3. Memory and Semis as AI Bellwethers
Bespoke-style thinking (semis and memory as "the transports of the 21st century") was echoed by the sell-off following Chinese competitive news. Memory stocks are acting as the most sensitive barometer for AI capex sentiment, with price-based margin expansion (not unit growth) having driven gains since 2024.
4. Fiscal-Political Crosscurrents Into Midterms
With gridlock scenarios historically outperforming unified government (per Morgan Stanley's Monica Guerra), and energy/affordability emerging as the top voter issue, the midterms are becoming a macro variable investors are explicitly pricing, particularly around AI data center headline risk. ---
Sentiment Analysis
Overall Market Sentiment: Cautiously Constructive
Despite a down day and weak breadth, guests broadly argued much of the bad news is already priced into underperforming sectors, setting up earnings season as a potential positive catalyst.
Risk Factors Highlighted
Weak market breadth: Only ~34% of large stocks have outperformed the S&P 500 over the trailing 12 months, a near-historic low, masking index-level strength.
Chinese chip competition: CXMT's new memory chip generation triggered a sharp sell-off in US memory and optical names.
Rate-sensitive bond portfolio losses: Rising yields are pressuring bank book values and capital ratios heading into Q3 earnings.
Geopolitical energy shocks: Middle East attacks and a collapsing Russia-Ukraine "energy ceasefire" are keeping oil prices elevated and volatile.
AI-driven deposit flight: Analysts flagged a nascent risk that AI agents could auto-shift deposits to higher-yielding accounts, pressuring bank profitability.
Contradictory AI-rates narrative: Kettner flagged an inconsistency in markets simultaneously pricing AI-driven higher structural growth (and rates) while also doubting AI earnings monetization.
Adobe's structural risks: New CEO execution risk, freemium model transition uncertainty, and AI disintermediation concerns stack up simultaneously.
Fiscal cliff into 2027: HSBC's Kettner warned that one-time fiscal support (tax/tariff refunds, CapEx incentives) will not repeat next year, risking negative growth surprises.
