Legendary investor Warren Buffett has repeatedly recommended that most individual investors place 90% of their equity allocation into a low-cost S&P 500 index fund and 10% into short-term government bonds. In his 2013 letter to Berkshire Hathaway shareholders, he explicitly suggested Vanguard’s S&P 500 ETF as the preferred vehicle. Launched in 2010, this ETF embodies Buffett’s principles of broad diversification, minimal trading and rock-bottom fees, and its stewardship by Vanguard ensures an expense ratio of just 0.03%. As of the end of 2025, the ETF held more than $1.5 trillion in assets under management, making it one of the largest and most liquid pools of U.S. large-cap exposure worldwide.

With rapid advances in artificial intelligence driving earnings growth among megacap technology companies, the Vanguard S&P 500 ETF offers investors a forward-compatible way to capture sector shifts without the challenge of picking individual winners. Technology names account for approximately 37% of the fund’s weight, while financial services and consumer discretionary represent another 24%. Though the ETF trades at a higher trailing price-to-earnings multiple compared with its own five-year average, its broad market coverage gives investors access to AI beneficiaries as well as traditional value sectors, smoothing volatility and avoiding single-stock concentration risk.

When compared with its largest competitor, the SPDR S&P 500 ETF Trust, the Vanguard S&P 500 ETF delivers a clear edge on cost and income. Both funds track the same index and exhibit identical beta and five-year drawdown characteristics, yet the Vanguard ETF charges just 0.03% annually versus 0.09% for the SPDR fund. That fee differential translates into savings of $6 per $10,000 invested each year. Meanwhile, its dividend yield has averaged around 1.12% over the past 12 months, slightly above the peer’s 1.06%, resulting in incremental payout income for long-term shareholders while maintaining top-tier liquidity.
