This Warren Buffett-Approved Investment Could Turn $300 Per Month into $1 million.

In This Article:

Warren Buffett is known for stock picking, selecting excellent long-term companies trading at reasonable or even dirt cheap prices and holding on for the long term. Using this strategy, he's helped Berkshire Hathaway's portfolio to achieve a compounded annual gain of almost 20% over the past 58 years. This is compared to the compounded annual increase of 10% for the S&P 500 index.

But Buffett also is a strong believer in another investing move that's a lot easier than stock picking -- it doesn't require research, specific knowledge of a particular company or industry, and it's proven itself to be a winner over time. In fact, Buffett owns this type of asset himself, an investment that complements his hand-picked stocks portfolio, and he's suggested that it's the ideal investment for a non-professional investor. If we use history as a guide, this asset could turn $300 per month into $1 million. Let's find out more.

Betting on stock market leaders

So, what is this Buffett approved strategy? It's the investment in an S&P 500 Index fund, a move that allows you to bet on all of the companies currently fueling the U.S. economy. Buffett holds the SPDR S&P 500 ETF Trust (NYSEMKT: SPY) as well as the Vanguard S&P 500 ETF in his portfolio -- both make great investments, but we'll use the SPDR fund as an example here.

These funds include the same companies found in the S&P 500 at the same weighting, and as a result, they track the performance of the index. Since the goal of the index is to measure the performance of major leaders of the times, stocks included are reviewed on a quarterly basis -- during those reviews, additions and deletions are announced. For example, this year the index invited high-growth technology companies Palantir Technologies and Super Micro Computer to join.

This means when you're invested in the S&P 500 through an index fund, you're always invested in the day's most prominent players -- and in fields that are making the biggest gains. For example, technology stocks, with a weighting of 32%, are the most heavily weighted in the index and in the funds that track it. The SPDR fund's top positions include Apple, Nvidia, and Microsoft, each representing more than 6% of the fund.

At the same time, these funds offer you a great deal of diversification, with positions in 10 other industries. This allows you to benefit from top players in many areas -- without having to become an expert in these companies and fields.
