3/1 US Stock Market Weekly Analysis - Rally Led by AI Infrastructure and Media Mega Deal

March 01, 2026 Weekly Market Analysis

## This Week's Core Theme: 'Selective Rally' Created by AI Infrastructure and Media Mega Deal

Over the past 10 days (10D), 10 out of 11 US stock market sectors rose, creating an overall positive sentiment. In particular

- Communication Services (+5.59%)

- Energy (+5.29%)

- Utilities (+5.27%)

rose strongly and led the market. In contrast, Consumer Discretionary (-0.52%) was the only declining sector, showing that concerns about discretionary spending remain.

There are three major factors behind this trend.

1. AI Infrastructure Investment Boom – Hardware and measurement equipment companies like Dell and Keysight presented strong earnings and guidance, spreading expectations of AI benefits across the technology and industrial sectors. (barrons.com)

2. Geopolitical Risks Surrounding Energy and Commodities – Tensions over Iran and Middle East uncertainty supported oil prices and related stock prices. (annas-daybreak-news.beehiiv.com)

3. Media and Content Industry Restructuring – Paramount Skydance announced plans to acquire Warner Bros Discovery, raising expectations for media consolidation and causing related stocks to surge. (decider.com)

Looking at the 30-day (30D) and 120-day (120D) trends, while the strength in energy and defensive sectors continues, financial stocks show 'structural weakness' with poor performance over both short and medium terms.

## Sector Performance: Who Led the Trend?

### 1) Communication Services: Rerating Ignited by Media Mega Deal

- 10D Return: +5.59% (1st out of 11)

- 30D: -1.92% → Short-term rebound sentiment

- 120D: +0.95% → Attempting to break out of a range

The surge in Paramount Skydance (PSKY, +30.63%) significantly boosted sector returns. Paramount Skydance announced a mega deal to acquire Warner Bros Discovery for approximately $110 billion, being re-evaluated as a 'content giant' bundling CNN, CBS, HBO, and various popular franchises.

This deal goes beyond a simple M&A

- Intensified streaming competition → Strengthened need for economies of scale

- Expanded content library → Subscription and advertising revenue leverage

- Cost synergies (expected around $6B) → Expected margin improvement

comes with these narratives, assigning a restructuring premium across media and entertainment. The market interprets this move as a 'signal of more consolidation and restructuring,' spreading revaluation expectations to other media and cable companies.

### 2) Energy & Utilities: Preference for 'Stable Cash Flow' Amid Geopolitical Risks

- Energy 10D: +5.29% / 30D: +17.92% / 120D: +30.89%

- Utilities 10D: +5.27% / 30D: +11.08% / 120D: +16.15%

Energy and utilities are strong across all 10D, 30D, and 120D periods, with this week's gains representing a continuation of a clear trend.

Behind this are

- Oil prices are holding relatively firm due to geopolitical tensions over Iran and Middle East risks, (annas-daybreak-news.beehiiv.com)

- and preference for utility cash flows centered on regulated base and long-term contracts is re-emerging in a high interest rate environment.

Land and royalty players like Texas Pacific Land (TPL, +27.34%) can show elastic returns in the current environment because leverage effects work significantly even when oil prices remain above a certain level.

### 3) Healthcare: 'Growth + Defense' Combination Amid Volatility

- 10D: +3.52% / 30D: +0.35% / 120D: +12.28%

Healthcare was nearly flat in the short term (30D), but this week (10D), growth-oriented stocks led a rally and achieved a rebound.

- Moderna (MRNA, +28.27%): Gained momentum with expectations of next-generation vaccine and cancer drug pipelines based on mRNA platforms, along with renewed focus on variant virus issues.

- Molina Healthcare (MOH, +15.48%), Centene (CNC, +14.55%): Managed care (MCO) players focused on Medicaid and Medicare, where stable member base and cost management capabilities are being re-evaluated despite political and regulatory risks.

Healthcare has

- defensive demand (essential medical services) and

- growth through innovation pipelines

as a sector, and is once again demonstrating the typical pattern of increased fund inflows as economic volatility increases.

### 4) Technology: AI Infrastructure Beneficiaries Strong, Growth Stocks Overall Adjusting

- 10D: +1.71% (rising but with large divergence within the sector)

- 30D: -3.07% → Still in adjustment phase on a monthly basis

- 120D: +15.89% → Clear uptrend over the medium term

While it appears that tech stocks only rose modestly this week (10D), the real story is the extreme divergence between AI infrastructure beneficiaries and other growth stocks.

- Keysight Technologies (KEYS, +33.92%): Surged after announcing earnings surprises and aggressive growth guidance based on AI data center, 6G, and defense demand. Revenue grew in the 20% range year-over-year, and next quarter guidance also significantly exceeded consensus, with measurement and test equipment demand for AI infrastructure and defense modernization cited as the key driver. (investing.com)

- Dell Technologies (DELL, +31.25%): Presented very strong Q4 figures with revenue +39% YoY, AI server revenue +300%+ growth, and AI server backlog over $40 billion, causing shares to surge over 20%. Guidance that AI server-related revenue will maintain double-digit growth in coming years, along with dividend increases and expanded share buybacks, also boosted investor sentiment. (barrons.com)

- Block (listed as XYZ, +29.25%): Rebounded as fee growth and cost control achievements in payments and fintech came into focus.

Meanwhile, during the same period

- Communication Services (+1.64%) and Energy (+1.54%) continued their strength,

- Financials (-2.32%) and Technology (-0.38%) saw profit-taking selling pressure.

With concerns about AI overvaluation and inflation re-acceleration coming into focus, which pressured growth stocks, this suggests that short-term volatility remains elevated. (tradingkey.com)

## Next Week's Key Points

### 1) Inflation Data and Fed Communication

- Inflation and employment figures to be announced in the next 1-2 weeks could reset expectations regarding the timing and magnitude of rate cuts.

- Fed officials' comments could amplify volatility in growth stocks (especially high-valuation AI-related stocks).

### 2) Whether AI Infrastructure Cycle Spreads

- Strong results from Dell and Keysight this week suggest that AI infrastructure investment is now entering a full CAPEX cycle.

- Guidance from other semiconductor, equipment, and server companies to be announced next week and beyond will be key checkpoints for confirming the breadth and depth of AI demand.

### 3) Follow-up Developments in Media and Entertainment M&A

- Initial comments from policy and regulatory authorities on the Paramount Skydance–Warner Bros Discovery deal,

- Strategic responses from other media and streaming companies (partnerships, sales, mergers, etc.)

could lead to continued revaluation of valuations within the Communication Services sector.

### 4) Whether Financial Sector Has Found 'True Bottom'

- Unless uncertainty about rate and regulatory environments abates, financial stocks may only bounce within a short-term trading range.

- Confirmation is needed on whether major banks, insurance, and asset management companies' future guidance and trends in loan loss provisions and fee income show concurrent improvement.

To summarize, this week's market was a selective rally led by three pillars—'AI Infrastructure, Media Mega Deal, and Energy Defense'—while financials and some high-growth stocks faced headwinds. Next week, inflation data, policy, and additional earnings reports will be key focal points in determining whether this selective rally spreads to a broader market.
