Warren Buffett is one of the world’s most iconic investors. He served as CEO of the Berkshire Hathaway (NYSE: BRKA) (NYSE: BRKB) holding company from 1965 to 2025, turning it into a $1 trillion conglomerate with numerous subsidiaries, a stock portfolio worth over $350 billion, and another $365 billion in cash.

Berkshire stock returned 19.7% annually during Buffett’s 60-year tenure, so an investment of $500 in 1965 would have grown to a whopping $24 million by the end of 2025. But he was a seasoned professional, so he always knew the average investor would struggle to replicate his performance. That’s why he consistently advocated exchange-traded funds (ETFs) that track a diversified index, like the S&P 500.

America’s best stocks from 11 economic sectors

The S&P 500 is the most widely followed U.S. stock market index for a couple of reasons. First, it’s made up of 500 companies from 11 different sectors of the economy, so it’s highly diversified. Second, it has very strict entry criteria: its members must maintain a market capitalization of at least $22.7 billion and be profitable. But even after those boxes are ticked, a special committee ultimately decides which companies make the cut.

The S&P is weighted by market capitalization, so the largest companies in the index have a much higher representation than the smallest. Therefore, despite its diversified composition, the information technology sector has a massive weighting of 36.6% because it’s home to five companies worth $1 trillion or more (Nvidia, Apple, Microsoft, Broadcom, and Micron Technology).

Below are the 11 sectors that make up the Vanguard S&P 500 ETF, along with their weightings and the three largest companies in each.

The technology sector is exerting a particularly strong influence on the performance of the S&P 500 right now, thanks to the artificial intelligence (AI) revolution, which began to gain momentum when OpenAI’s ChatGPT application surpassed 100 million users in early 2023. In fact, if we exclude the sector’s contribution over the last three-and-a-half years, the S&P 500’s return drops from 101% to just 63%.

Simply put, the Vanguard ETF gives investors exposure to the fastest-growing area of the market in a diversified manner, which is why it’s a popular long-term investment option.

Taking Buffett’s advice could yield spectacular results

The S&P 500 has returned 10.7% since its inception in 1957 (assuming all dividends were reinvested). But it has delivered an accelerated return of 13.9% since Buffett recommended the Vanguard S&P 500 ETF in 2014, primarily thanks to the tech sector.

Past performance isn’t always a reliable indicator of future results, but a 25-year-old investor could build a very nice retirement fund using the Vanguard ETF if its historical returns persist. Below are two potential outcomes.

Those results don’t include costs, but with an expense ratio of just 0.03%, investors would incur an annual fee of just $3 for every $10,000 they have parked in the Vanguard ETF.

To conclude, investors probably shouldn’t sell their entire position at retirement age, because compounding yields the greatest benefits over time. With a large enough balance after 40 years, the subsequent annual returns could provide a significant income to fund life after employment.
