Warren Buffett’s legendary investment in the S&P 500 has once again proven its mettle. In 2007, Buffett made headlines with a bold $1 million bet, challenging hedge fund managers by investing in a simple S&P 500 index fund. By 2017, he had won, demonstrating the power of index investing.
Today, many individual investors follow Buffett’s example, opting for the S&P 500 through exchange-traded funds like SPDR S&P 500 ETF Trust (SPY), iShares Core S&P 500 ETF (IVV), and Vanguard S&P 500 ETF (VOO). These funds represent a significant portion of the U.S. ETF market, with VOO leading in net inflows this year.
Despite the index’s impressive performance, climbing 20% year-to-date and 33% over the past 12 months, experts warn that it may be time to diversify. Larry Adam from Raymond James predicts a softer economic landing, with expectations of more muted stock performance in the future.
The S&P 500’s concentration risk—particularly in the information technology sector, comprising 31.7% of the index—raises concerns. Sean Williams from Cadence Wealth Partners advises investors to consider other areas like international, small- and mid-cap companies, and real estate.
For broader exposure, experts suggest exploring total market portfolios like the Vanguard Total Stock Market ETF (VTI) or undervalued small value ETFs. While the S&P 500 remains a robust long-term strategy, diversifying can help mitigate risks and capture a wider array of opportunities.
