Warren Buffett, widely regarded as one of the greatest investors of all time, has long been an advocate of low-cost index funds, especially the S&P 500. But why does he favour this simple investment approach over stock picking?
If you’re wondering why should you consider investing in the first place, understanding Buffett’s philosophy can offer valuable insights. What if you had followed his advice and consistently invested in the S&P 500 over time? Would it have made you wealthier today?
Let’s break down Buffett’s reasoning, his famous million-dollar bet on index funds, and what your investments could have grown into had you started investing $100 a week in the S&P 500 years ago.
Why does Warren Buffett recommend S&P 500 index funds?
Despite his legendary success in picking individual stocks, Buffett has consistently advised everyday investors to take a simpler and safer route—investing in an S&P 500 index fund. But why does he believe this is the best approach for most people?
- A Low-Cost, High-Return Strategy: Buffett believes that actively managed funds, which come with high fees and complex strategies, often fail to beat the market over the long run. Index funds, which track the overall market, are low-cost and have historically delivered strong returns.
- Outperforming Investment Professionals: Buffett famously stated, “By periodically investing in an index fund, the know-nothing investor can actually outperform most investment professionals.” This means that instead of trying to pick winning stocks or time the market, regular investments in an index fund can yield better long-term results.
- A Strategy for All Market Conditions: In an interview with CNBC, Buffett reinforced his view, saying, “Consistently buy an S&P 500 low-cost index fund. I think it makes the most sense practically all of the time… Keep buying it through thick and thin, and especially through thin.” In other words, whether the market is up or down, staying invested pays off in the long run.
Did Buffett prove that index funds are better than hedge funds?
Buffett didn’t just talk about index funds—he put his money where his mouth was. In 2007, he made a $1 million wager that the S&P 500 would outperform a group of hedge funds over 10 years.
A hedge fund manager, Ted Seides, accepted the challenge and picked five hedge funds that he believed would deliver better returns than the S&P 500. So, who won the bet?
By the end of the decade, the results were clear:
- The S&P 500 delivered an average annual return of 7.1%
- The hedge funds returned only 2.1% per year
Seides admitted defeat before the bet even concluded. Except for 2008, when the market crashed, the S&P 500 outperformed hedge funds every single year of the wager. This experiment further proved Buffett’s belief that keeping investments simple and low-cost leads to better long-term results.
What would your money look like if you had invested in the S&P 500?
Now, let’s get practical. If you had invested $100 a week in an S&P 500 index fund over time, how much would you have today?
The last decade has been even better, with the S&P 500 delivering an average annual return of 12.68%. Here’s how your money would have grown:
- $1,000 would grow up to $3,300
- $5,000 would grow up to $16,498
- $10,000 would grow up to $32,997
- $20,000 would grow up to $65,993
- $50,000 would grow up to $164,983
- $100,000 would grow up to $329,965
Buffett’s confidence in index funds is so strong that he has incorporated them into his own estate planning strategy. In his 2013 annual letter to Berkshire Hathaway shareholders, he revealed his instructions for how his wealth should be managed after he passes away.
He advised the trustee overseeing his estate to:
- Put 90% of his assets into a low-cost S&P 500 index fund
- Invest the remaining 10% in short-term government bonds
This simple plan reflects Buffett’s belief that, even with billions of dollars at stake, index funds offer the best long-term returns with minimal effort.
What can you learn from Buffett’s investment advice?
So, what does Buffett’s advice mean for you as an investor? Here are some key takeaways:
- Stay consistent – Investing small amounts regularly in an S&P 500 index fund can build wealth over time.
- Ignore market noise – Market downturns happen, but history shows that staying invested leads to growth.
- Think long-term – The longer you stay invested, the more powerful compounding becomes.
If you’re looking for an investment strategy that requires little effort but delivers solid results, Buffett’s approach could be worth considering.
