Momentum Movers: 10 Large-Caps Outperforming the S&P 500

The S&P 500 has long been the benchmark for U.S. equities, but in 2025, a select group of large-cap stocks has surged ahead, driven by explosive earnings growth, expanding profit margins, and positive revisions to forward-looking expectations. These companies—anchored in artificial intelligence, cloud computing, and semiconductor manufacturing—have not only outpaced the index but also redefined the rules of value creation in a technology-driven economy. For investors seeking to build a high-conviction momentum portfolio for 2025–2026, these 10 stocks offer a compelling case for capital allocation.

The Case for Momentum Investing

Momentum investing thrives on the compounding effects of strong fundamentals and market sentiment. The 10 stocks analyzed here exhibit three key attributes:
1. Earnings Growth: Revenue and operating income increases of 15% or more year-over-year.
2. Margin Expansion: Rising gross and operating margins, reflecting pricing power and operational efficiency.
3. Positive Earnings Revisions: Upward adjustments to analyst estimates and management guidance, signaling confidence in future performance.

These metrics, when combined, create a self-reinforcing cycle of investor optimism and capital inflows. Let's examine the top performers.

1. Nvidia (NVDA): The AI Chipmaker's Dominance

Nvidia's Q2 2025 results were nothing short of extraordinary. Revenue hit $30 billion, a 122% year-over-year surge, driven by its Hopper and Blackwell GPU architectures. Data Center revenue alone accounted for $26.3 billion, up 154% YoY. Non-GAAP earnings per share rose 152%, and the company guided for $32.5 billion in Q3 revenue. Analysts have upgraded estimates despite recent volatility, with a forward P/E of 33.2.

Why Invest? Nvidia's dominance in AI and data center infrastructure positions it as a critical enabler of the next computing era. Its ability to command premium pricing and scale production ensures margins remain robust.

2. Microsoft (MSFT): Cloud and AI Synergy

Microsoft's Azure cloud revenue surpassed $75 billion annually, growing at 34% YoY. The company's AI tools, including Microsoft Fabric and Copilot, are driving enterprise adoption. Operating income rose 17% in FY2025, with EBIT margins expanding to 45%. Management's guidance for $15.8 billion in Q3 revenue reflects confidence in its AI-driven cloud strategy.

Why Invest? Microsoft's dual focus on cloud infrastructure and AI software creates a moat that is difficult to replicate. Its ecosystem of developers and enterprise clients ensures recurring revenue and margin resilience.

3. TSMC (TSM): The Semiconductor Backbone

TSMC's Q2 revenue of $30 billion (up 44% YoY) underscores its role as the world's leading foundry. Its 3nm chips now account for 24% of revenue, and HPC (high-performance computing) demand is accelerating. With a forward P/S ratio of 10.4 and a projected $122 billion in 2025 revenue, TSMC is a linchpin for AI and semiconductor innovation.

Why Invest? TSMC's technological leadership and long-term contracts with clients like Nvidia and Apple ensure steady cash flows. Its U.S. expansion and R&D investments further solidify its growth trajectory.

4. Broadcom (AVGO): AI Semiconductor Powerhouse

Broadcom's Q2 revenue of $15 billion (up 20% YoY) was fueled by $4.4 billion in AI semiconductor sales. Non-GAAP net income of $7.8 billion and free cash flow of $6.4 billion highlight its profitability. The company's AI revenue is projected to grow 46% in 2025, driven by hyperscale demand.

Why Invest? Broadcom's diversified portfolio and high-margin AI chips make it a safe haven in a volatile sector. Its disciplined capital allocation and shareholder returns (via buybacks and dividends) add to its appeal.

5. ServiceNow (NOW): SaaS Scalability

ServiceNow's Q2 subscription revenue grew 22.5% YoY to $3.1 billion, with non-GAAP operating margins of 29.5%. Its AI Control Tower and Workflow Data Network are reshaping enterprise automation. Current RPO of $10.9 billion reflects strong client retention.

Why Invest? ServiceNow's SaaS model and AI-driven product innovations position it to capture market share in the $1 trillion enterprise software industry. Its 16.5% YoY free cash flow growth is a testament to its operational discipline.

6. Apple (AAPL): Services and AI Integration

Apple's Services division grew 12% YoY, contributing most of its revenue growth. While hardware sales lagged, the company's AI integration in iOS and services (e.g., Apple Music, iCloud) is boosting margins. A forward P/E of 28x is justified by its 1 billion+ user base and ecosystem stickiness.

Why Invest? Apple's transition to a services-led model and AI enhancements create long-term value. Its premium pricing power and brand loyalty ensure consistent cash flows.

7. Alphabet (GOOG): Advertising and Cloud Resilience

Alphabet's Q2 revenue rose 10.4% YoY to $88.3 billion, with Google Cloud growing 32% and advertising revenue up 10.9%. EBIT margins hit 53%, and capex guidance increased to $85 billion for 2025.

Why Invest? Alphabet's dominance in digital advertising and AI-driven cloud services ensures recurring revenue. Its ability to scale AI infrastructure (e.g., Gemini models) positions it for sustained growth.

8. Amazon (AMZN): AWS and Advertising Synergy

Amazon's AWS revenue grew 18% YoY, while advertising sales surged 23% to $15.7 billion. The company's $118 billion capex plan for 2025 underscores its commitment to AI and cloud leadership.

Why Invest? Amazon's dual engines of AWS and advertising provide a durable competitive advantage. Its scale and innovation in AI (e.g., Bedrock) ensure it remains a top-tier player.

9. Meta (META): Advertising and Metaverse Momentum

Meta's Q2 revenue rose 21.5% YoY to $40.6 billion, with EBIT margins hitting 53%. Advertising growth on Facebook and Instagram, coupled with AI-driven ad performance, is driving profitability.

Why Invest? Meta's advertising moat and AI integration in its platforms (e.g., Llama 3) position it to outperform in the metaverse and social media sectors.

10. Tesla (TSLA): Energy and Robotics Diversification

Tesla's energy and storage division earned nearly as much as its automotive segment, while its Optimus robot and robotaxi plans signal a shift toward robotics. EBIT margins in vehicle sales remain strong at 25%.

Why Invest? Tesla's diversification into energy and robotics reduces reliance on EVs alone. Its first-mover advantage in autonomous driving and AI-powered robotics could unlock new revenue streams.

Building the Momentum Portfolio

To construct a high-conviction portfolio, investors should allocate capital based on sector exposure and growth potential:
- AI and Cloud (50%): Nvidia, Microsoft, TSMC, Alphabet, Amazon.
- Semiconductors and SaaS (30%): Broadcom, ServiceNow.
- Consumer and Robotics (20%): Apple, Meta, Tesla.

Investment Advice

1. Dollar-Cost Averaging: Given the volatility of AI and tech stocks, a staggered entry strategy mitigates risk.
2. Monitor Earnings Revisions: Track analyst upgrades for companies like Nvidia and TSMC, which often signal momentum shifts.
