Why the Nasdaq Is Beating the Dow and S&P 500 Today

• Nvidia, Apple, and Microsoft collectively represent 26% of the Nasdaq's weight but only 18% of the S&P 500 and 10.6% of the Dow, amplifying their 2%+ gains' impact on the tech-heavy Nasdaq
• Microsoft rose 2.7% on news about OpenAI remaining an Azure client, Nvidia gained 2.2% ahead of Q4 earnings, and Apple climbed 0.9% on expanded Texas manufacturing plans
• The Dow's price-weighted structure (versus market cap weighting) dilutes big tech's influence, with financial stocks like Goldman Sachs and IBM driving more of its 0.6% gain

Market Summary: Nasdaq Outperforms Amid Tech Rally

Index Performance

All three major U.S. indices posted gains on February 25, 2026, though with varying magnitude. The Nasdaq Composite led with +1.3% (+291.36 points to 23,155.04), followed by the S&P 500 at +0.8% (+55.93 to 6,946.00), while the Dow Jones Industrial Average trailed at +0.6% (+281.49 to 49,455.99).

Key Drivers

The divergent performance stems from index construction differences and tech sector concentration:

Tech Giants' Weight:

• Nvidia, Apple, and Microsoft collectively represent 26% of the Nasdaq, but only 18% of the S&P 500 and 10.6% of the Dow
• All three companies rose 2%+ during the session

Individual Stock Movements:

• Nvidia (NVDA): +2.2% ahead of Q4 2026 earnings report
• Microsoft (MSFT): +2.7% following confirmation of OpenAI as reliable Azure client
• Apple (AAPL): +0.9% on expansion of Mac mini manufacturing in Houston, Texas
• IBM: +3.7%, third-largest Dow mover with 2.8% index weight
• Goldman Sachs (GS): +1.9%, benefiting from relief after State of the Union address avoided new tariffs

Market Implications

The Dow's price-weighted methodology dilutes big tech's influence compared to the market-cap weighted Nasdaq and S&P 500. Financial services stocks rallied approximately 3% on reduced tariff concerns following the State of the Union address. The session demonstrates how structural index differences amplify sector-specific moves, particularly in technology.
