CNBC Halftime Report
2026-05-12 · Hosted by Scott Wapner · CNBC
Executive Summary
The Halftime Report investment committee grappled with whether the record-setting AI rally has further to run or is entering a dangerous final phase. The S&P 500 added ~0.3% and Nasdaq ~0.4%, with the momentum factor up 30% in the current quarter and the SMH semiconductor ETF up 50% since March lows. The committee debated Micron’s extraordinary run (more than doubled in under six weeks), Nvidia’s $5.4 trillion market cap, Corning’s AI infrastructure positioning, financials sector divergence, and the energy trade via Diamondback Energy. Key consensus: stay long AI momentum but manage position sizing; the rally is fundamentally supported but cyclical risks in memory stocks and private credit stress deserve attention.
Key Stories & Changes
1. AI Momentum Factor — Record Quarter
Momentum factor up 30% so far in Q2 2026; growth stocks up 20% in the quarter; value only up 6%; quality up 9%
SMH (semiconductor ETF): up 50% since March lows; 60% above its 200-day moving average
Six consecutive weeks of gains for AI/momentum names; Nvidia at $5.4 trillion market cap — world’s most valuable company
Amazon, Alphabet, Apple: all recorded new all-time highs in recent days; Nvidia’s ATH is today
Jefferies published “AI Unicycle” report showing AI-supported earnings driving essentially all S&P performance in 2026
2. Micron — The Poster Child of the Melt-Up
Micron (MU): more than doubled in less than 45 days; Weiss disclosed buying at $3.30 on March 30 and again ~10% higher on April 9
$32 billion of Micron shares traded in one day; SK Hynix doubled over 18 sessions
Trading at ~9x next year’s earnings (if sold out with penalty-protected contracts)
Weiss: “this stock should not have more than doubled in a month and a half” — acknowledges greed component while remaining long
Setti: Micron is a commodity stock like copper or steel; trades at lowest PE when earnings peak (reverse of typical growth stock)
Picker: if a more efficient AI model surfaces that reduces compute demand, does this reverse? Committee: yes, demand duration is the key variable
3. Nvidia — Still the Leadership Stock
Nvidia remains core long across all committee members; ETF maintained through recent rebalancing
Joe Terranova (ETF): trimmed from 35% financial allocation to 15%; redirected toward AI infrastructure names
Nvidia’s key advantage per Terranova: chips “eliminate the need to stack,” creating faster and more efficient AI output
Nvidia PE has “caught up” to its valuation as earnings kept growing; now seen as appropriately priced relative to order book
Corning (GLW): flagged as critical AI infrastructure play — optic fiber for data centers; Meta supply deal through 2030; Nvidia investment partnership announced
Apple classified as a “value stock” in upcoming Russell reclassification; Caterpillar now a “growth stock” — illustrating how AI has reshuffled sector definitions
4. Financials Sector Divergence
Financials: second worst sector year-to-date despite recent big-bank earnings beat
Winners: Morgan Stanley (up 28% YTD, wealth management/capital markets heavy), Goldman Sachs, Charles Schwab, T. Rowe Price, Raymond James, CME Group, Virtue Financial
Losers: Wells Fargo (broke down), JP Morgan, Bank of America (on the weak side); consumer finance names, insurance names weak
Citigroup: CEO Jane Fraser’s restructuring complimented but stock no longer the same bargain as before
KKR Future Standard Fund: took a $560 million loss from troubled assets — private credit “hot streak over” per WSJ
AI disintermediation threat: Anthropic’s new product suite can do investment banking pitch books, credit analysis — threatens legacy financial data providers (FactSet, Broadridge, S&P Global)
Committee reduced financial allocation from 35% to 15% YTD
5. Energy Sector — Diamondback Call of the Day
Diamondback Energy (FANG): Bernstein reiterated as top oil idea; Permian Basin position; potential acquisition target (~$55 billion market cap)
Joe Terranova: Permian rig count down ~15% over the past year; expects uptick; US barrel is “most vital in the world”
Also likes: refiners — Phillips 66, Marathon, Valero (personal position)
Shannon Sikosha: Exxon and Chevron easier beta-to-oil plays; refiners offer more targeted value
Oil prices approaching $100 uncomfortably; Weiss: “I’m not sure the S&P is going to like that if it gets through 100”
6. Private Markets Risk & IPO Impact
SpaceX, Anthropic, OpenAI potential mega-IPOs: could suck demand from current AI semiconductor trade
Private market valuations make public tech “look cheap” (OpenAI, SpaceX valuations dwarf public comparables)
Weiss: if any of these bubble, real economic damage could follow — but doesn’t see that happening near term
Cerebras IPO (already upsized): first test of AI IPO appetite this week
Trends Identified
1. The AI Trade Is Now a Momentum Factor Play
Terranova’s framing is precise: the market has taken on the character of a momentum-factor trade, not a fundamentals-first trade. The momentum factor up 30% in Q2 while quality is up only 9% tells you that quality-adjusted AI exposure is being left behind by pure momentum buying. This creates the setup for a violent intraday unwind — Terranova explicitly predicted a 4–5% momentum-factor down day will occur — while not necessarily ending the longer-term uptrend.
2. The Semiconductor Cycle Question Is Unresolved
The committee’s most substantive debate centered on whether AI has “smoothed” the semiconductor cycle or merely extended the upcycle. Setti’s commodity-stock analogy is compelling: Micron trades like copper — lowest PE at earnings peak, meaning the market is already sniffing the cycle top. But Shannon Sikosha’s counter is also valid: the AI demand pie continues to grow faster than efficiency gains compress individual company orders. Moore’s Law being “dead” (as Form Factor’s CEO also noted) means factory buildout takes years, creating structural supply constraint that lengthens upcycles.
3. Financials Sector Is Bifurcating Along AI Exposure Lines
The pattern is now clear: capital markets and wealth management names (Goldman, Morgan Stanley, Schwab) are outperforming while commercial lending and credit-exposed banks (Wells, JP Morgan) are struggling. AI disintermediation is beginning to show up as a fundamental concern for data providers and legacy financial services companies. The committee reduced financial exposure dramatically (35% to 15%) in response.
4. Energy as Portfolio Insurance
Jim Carron (Morgan Stanley, covered on Fast Money) and the Halftime committee are both using oil as a hedge against geopolitical tail risk — explicitly buying oil futures as insurance in case Iran talks collapse. Diamondback in the Permian is the preferred pure-play; refiners are the preferred value expression. The $100/barrel threshold is seen as a key market psychology level. —-
Sentiment Analysis
Overall Market Sentiment: Bullish but Nervously Positioned
The committee is long AI/momentum but increasingly anxious about breadth, cycle position, and what happens when the music stops. No one is selling aggressively, but trimming, rebalancing, and hedging with energy are all visible.
Risk Factors Highlighted
Momentum factor unwind risk: Terranova explicitly predicted a 4–5% single-day momentum-factor crash is coming; $32 billion of Micron trading in one day signals speculative excess
Memory cycle top signal: Micron trading at 9x forward earnings while commodity stocks (correct to sell at low PEs at earnings peaks) — historical precedent suggests this is the top of the cycle
Private credit contagion: KKR $560M loss from troubled portfolio assets; systemic concerns about private credit valuations spreading
AI disintermediation of financial services: FactSet, Broadridge, S&P Global face structural threat from AI doing pitch books, credit analysis, and data aggregation
Energy at $100/barrel threshold: Approaching a psychological level that historically triggers market concern and consumer spending contraction
IPO cannibalization of semiconductors: SpaceX, Anthropic, OpenAI mega-IPOs could redirect capital away from current semiconductor momentum names
Narrow market breadth in final stages: Healthcare, consumer staples, financials (ex-capital markets) all lagging — historical pattern of secular bull market exhaustion
Fed uncertainty under new Chair: Kevin Warsh confirmation vote imminent; divided FOMC faces above-target inflation plus energy shock; June meeting will be his first presser
