What is the S&P 500?

Founded in 1957, the S&P 500 Index is a well-known global stock market index and is also seen as a barometer of the health of the U.S. stock market.

The S&P 500 index tracks the performance of 500 leading U.S. companies. Many of the world's most famous companies are in the S&P 500 index, such as Nvidia, Microsoft, Apple, Google, Tesla, and many others.

However, the S&P 500 index does not consist of an exact 500 stocks. Sometimes, the same company may issue several different types of shares (such as common and preferred shares) that are counted separately in the index.

Investing in the index means building an extremely diversified portfolio all at once, thus reducing the risk to investors.

S&P 500 Performance: Past and Future

Many academics are tracking the returns of the S&P 500, and Aswath Damodaran, a professor at New York University, is one of them. According to data compiled by Aswath Damodaran, over the 10 years ending December 2024, the average annual return of the S&P 500 index was 13.3% (including dividends).

The data also show that the S&P 500's average annual return of more than 10% has outperformed many other investments, including U.S. treasury bonds, corporate bonds, real estate, and gold.

Now, many analysts have forecasted that the S&P 500 will continue to rise in 2025. As of January 2025, Goldman Sachs and Morgan Stanley both forecast that the S&P 500 would rise to 6,500 by the end of 2025, which means that the total return rate, including dividends, will reach 10%.

David Kostin, chief U.S. equity strategist at Goldman Sachs, mentioned in the report that the reasons for bullishness include the solid expansion of the U.S. economy and the steady growth of corporate profits.

A JPMorgan research note makes a similar point. Dubravko Lakos-Bujas, head of global markets strategy at JPMorgan, noted that in 2025, the United States is likely to continue to be the engine of global growth because its economic cycle is in an expansionary state.

Lakos-Bujas also expects the S&P 500 to reach 6,500 in 2025, with the U.S. equities preferred over the eurozone and emerging markets.

Best way to invest in the S&P 500 for beginners

For beginners, the best way to invest in the S&P 500 is through a mutual fund or ETF, which is a safer choice than investing in a stock within the S&P 500 index.

Investing in an S&P 500 index fund or ETF means that you will invest in all industries and stocks within the index. You can significantly diversify your funds and risks and minimize the impact of market fluctuations. So for beginners, choosing mutual funds or ETFs is a better choice.

Based on my experience, I suggest you look at the following criteria when choosing a mutual fund or ETF.

Expense ratio: Mutual funds typically charge lower fees than actively managed funds, Because they are passively managed, their goal is to match the performance of the index rather than beat it. ETFs also have a low expense ratio, which is often between 0.03% and 0.1% annually.
Dividend yield: Many S&P 500 index funds or ETFs pay dividends, which can be reinvested and boost your long-term returns. But there are a few that don't, and you need to be aware of that before you invest.
Minimum Investment: Mutual funds generally have minimum investment amounts ranging from a few hundred dollars to several thousand dollars. For example, a Vanguard 500 Index fund (VFIAX) typically has a minimum investment of $3,000. In contrast, ETFs have a lower minimum investment than mutual funds or even no minimum investment.
Liquidity: ETFs have better liquidity and flexibility than mutual funds. Because ETFs can be traded on stock exchanges like ordinary stocks, while other funds can only be settled at the end of the trading day.

	Mutual funds	ETFs
Expense ratio	Low	Low (often between 0.03%-0.1% per year)
Dividend yield	Most of them, Yes	Most of them, Yes
Minimum Investment	Hundreds to thousands of dollars	Low or even no
Liquidity	High	Very high
