Warren Buffett Says Buying This Investment Is "The Best Thing" for Most People -- and It Could Make You a Millionaire

Key Points

The last few months have been rocky for the stock market, as major indexes have fluctuated wildly -- surging, plunging, and then surging once again.

With tariff policies changing by the day and experts warning about the impacts those tariffs may have on the job market and economy, many investors are unsure about what to expect going forward.

However, there's one Warren Buffett-approved investment that the legendary investor has said is a smart buy for nearly everyone. And with the right strategy, it could potentially turn a few hundred dollars per month into $1 million or more -- even accounting for any future stock market volatility.

A stable yet powerful investment

During Berkshire Hathaway 's 2020 annual meeting, Buffett discussed his investing strategy as well as his recommendations for other investors. While he notes that there are many different approaches out there, he says that "for most people, the best thing to do is to own the S&P 500 index fund."

This isn't the first time Buffett has recommended the S&P 500 index fund. In 2008, he made a $1 million bet that this type of investment could outperform a selection of actively managed hedge funds over 10 years. The S&P 500 index fund earned total returns of nearly 126% in that time, while the five hedge funds averaged returns of only around 36%.

An S&P 500 index fund includes all of the stocks from the S&P 500 (SNPINDEX: ^GSPC) itself, which is made up of 500 of the largest and strongest companies in the world. Only the most durable companies with histories of long-term growth are included in the S&P 500, making them more likely to survive periods of volatility.

In the last 25 years alone, the S&P 500 has earned total returns of just over 300% -- despite facing major downturns like the dot-com bubble burst, the Great Recession , the COVID-19 crash, and the bear market throughout 2022.

There are no guarantees that the S&P 500 will continue thriving if we face another recession or market crash, but based on its history of surviving even extreme volatility, its future looks incredibly promising.

Building a million-dollar portfolio

Even a relatively safe investment like the S&P 500 index fund can help you reach $1 million or more. Exactly how much you'll need to contribute per month, though, will depend mostly on your timeline.
