These sectors have driven much of the recent market gains.Dow Jones consists of only 30 blue-chip stocks and has lower weighting in tech (around 21%) and communications services (2%), but higher exposure to financials (27%). This more financial-heavy and less tech-centric composition means it misses out on large tech-driven rallies like the one led by companies such as Nvidia (NVDA).Analysts say the Dow's underperformance is not indicative of economic trouble but mainly reflects structural differences in index makeup and sector performance. The S&P 500 was set to log a fifth straight record close while the Dow had yet to hit a new high in 2025. The S&P 500 has significantly higher exposure to big tech and artificial intelligence (AI) companies, with about 33% in technology and 10% in communications services (which includes major tech giants). These sectors have driven much of the recent market rally. In contrast, the Dow Jones Industrial Average (DJIA) consists of only 30 blue-chip stocks and has lower tech exposure (around 21%) and communications services (2%), but a heavier weighting toward financials (27%). This sector mix means the Dow misses out on the large gains led by tech giants like Nvidia. The Dow is a price-weighted index, meaning stocks with higher share prices have more influence regardless of company size. For example, UnitedHealth Group, with a high share price, impacts the Dow more than major tech companies like Apple or Microsoft, which influences the Dow’s overall performance differently from the market-cap-weighted S&P 500. As a result, the S&P 500 has been propelled by a narrow group of megacap tech stocks and AI-related companies, while the Dow’s composition and weighting cause it to trail behind. Analysts do not see this divergence as signaling economic trouble but rather as a reflection of index structure and sector performance differences.
