Warren Buffett's Index Fund: A Safe Path to Wealth

Published December 22, 2024

For those aiming to build wealth, whether for retirement savings or to enhance their net worth, investing in the stock market stands out as one of the most accessible and secure routes to achieving long-term financial growth.

When seeking a straightforward and less risky way to participate in the stock market, an index fund can be a wise choice. An index fund aggregates a selection of securities into a single investment, allowing you to own a piece of hundreds of stocks with one purchase.

Among the many index funds available, one fund remains notable for its impressive history of weathering market downturns while consistently producing positive total returns. This fund holds the endorsement of renowned investor Warren Buffett.

By adopting the right investment approach, this fund could potentially help you accumulate a wealth of $1 million or more.

Wealth Generation with Minimal Risk

While no investment is entirely free of risk, the S&P 500 index fund is regarded as one of the safer options. This index fund tracks the S&P 500 (^GSPC 1.09%), which consists of stocks from some of the largest and most reputable companies across various industries in the U.S.—ranging from technology to financial services and consumer goods.

Investing in a single index fund allows for immediate diversification, which can significantly reduce risk. Generally, a diverse portfolio is better shielded from market fluctuations. Although S&P 500 index funds may still experience short-term volatility, they have a higher likelihood of recovering and yielding positive returns over the long term.

The S&P 500 boasts an excellent reputation for bouncing back from downturns. Research by Crestmont Research has shown that every 20-year period in the history of the S&P 500 has concluded with positive total returns. This means that if you had invested in an S&P 500 index fund at any time and held onto it for two decades, you would have profited.

A Strong Recommendation from Warren Buffett

Warren Buffett himself advocates for the S&P 500 index fund, owning two types of these funds through his conglomerate, Berkshire Hathaway: the Vanguard S&P 500 ETF (VOO 1.13%) and the SPDR S&P 500 ETF Trust (SPY 1.20%).

Buffett famously wagered $1 million that an S&P 500 index fund would outperform actively managed funds over a 10-year span beginning in 2008. His bet won, yielding returns of 125.8%, while the hedge funds received returns between 2.8% and 87.7%, averaging around 36%.

In a letter to shareholders following the completion of the bet, Buffett remarked that the five funds initially performed well, surpassing the index fund in 2008. However, in every year that followed for the next nine years, those funds collectively lagged behind the index fund.

Buffett's timeless lesson to investors: "Stick with big, 'easy' decisions and avoid unnecessary activity." This emphasizes that investors don't need to stress over the timing of the market or the perfect stock to invest in. Often, simply choosing a straightforward index fund and allowing it to grow for 10 or 20 years could yield better results.

Crafting a $1 Million Portfolio

Even with a conservative investment like the S&P 500 index fund, you can achieve significant financial rewards over the years.

The S&P 500 has historically returned an average of about 7% per year. While its performance may fluctuate yearly (in the last five years, it has varied from -19.44% to 28.88%), these annual shifts have averaged out to roughly 7% over the long term.

To illustrate, if you're aiming to reach $1 million with an average annual return of 7%, here’s what your monthly investment might look like based on your time frame:

Years to Invest Monthly Investment Total Value at End
20 $2,100 $1.033 million
25 $1,325 $1.006 million
30 $900 $1.020 million
35 $625 $1.037 million
40 $425 $1.018 million

While expectations should be grounded, it's essential to note that the S&P 500 might produce returns above the historical average. Notably, in 13 of the last 20 years, the index exceeded its 7% average annual return, with five of those years yielding returns over 20%.

In conclusion, maintaining a long-term investment strategy can lead to substantial wealth over time. Investing early and consistently, even with conservative expectations, could result in earning much more than you initially envision.
