7 of Vanguard's 11 Sector ETFs Are Crushing the S&P 500 in 2026. Here's My Favorite to Buy in March.

Group 1: Investment Opportunities in ETFs - Vanguard offers exchange-traded funds (ETFs) that track the performance of all 11 stock market sectors, featuring low expense ratios for diversified sector-specific investments [1] - The Vanguard Utilities ETF (NYSEMKT: VPU) is highlighted as a top sector fund to buy in March, indicating strong interest in utility sector investments [3] Group 2: Sector Performance Insights - In 2025, only three sectors—communications, tech, and industrials—outperformed the S&P 500, while in 2026, sectors like energy, materials, consumer staples, industrials, and utilities are all up 10% or more, with real estate and healthcare also outperforming the index [2] - The utility sector is traditionally seen as defensive, with steady cash flows and stable dividends, but it tends to underperform compared to sectors that benefit more from economic growth [4] Group 3: Electricity Demand and Growth Projections - The U.S. is experiencing a boom in electricity demand, driven by AI workloads and data center expansions, with a projected 1% increase in electricity use in 2026 and 3% in 2027, marking the strongest four-year growth period since 2000 when considering previous years [5] Group 4: Investment Challenges in the Utility Sector - The utility sector's structure complicates individual stock investments, as regulated electric utilities face limitations on benefiting from increased power demand due to federal regulations, but they enjoy virtual regional monopolies [6][7] - Examples of regional utility companies include Duke Energy, which serves specific states, and Southern Company, which operates both wholesale energy and electric utilities in the Southeastern U.S. [8]
