In this article, we’ll explore the differences between the S&P 500 and the MSCI World so that you can make a better-informed decision about which index to invest in. We will cover performance, country exposure, sector exposure, the availability of ETFs, and more!

MSCI World vs S&P 500 compared in a nutshell

Our team has compiled all the information discussed throughout the article into a table, so that it can be easier for you to observe the differences and make a decision.

What are the S&P 500 and the MSCI World indices?

The Standard & Poor’s 500, known as the S&P 500, is one of the primary indices in the United States. It comprises 503 large, established U.S. companies listed on the U.S. stock exchange, representing various sectors of the economy (Technology, Health Care, and so on). It also provides globally diversified growth through large US-based multinational companies.

The MSCI World Index tracks the performance of large and mid-cap company stocks in 23 developed markets worldwide, and it covers around 85% of the listed equities in each country.

Country diversification

The MSCI World Index includes large and mid-cap stocks from 23 developed countries, resulting in stocks from various countries being listed on different exchanges.

Country Weight
United States 70.89%
Japan 6.13%
United Kingdom 3.79%
France 3.16%
Canada 3.06%
Others 12.97%

Note: The weights listed in the table refer to Mar 29, 2024.

On the contrary, the S&P 500 exclusively focuses on large-cap US equities listed on US exchanges.

Given that, do you think a US-based company listed in the NASDAQ or NYSE has 100% US-country risk?

Around 40% of the revenues of the S&P 500 companies came from countries outside of the USA, which means that assessing the company’s country revenues (and, consequently, currency exposure) will help you better understand the actual country risks of the business, more about it in our article about understanding your country/currency exposure.

Sector diversification

Both indices focus on the same sectors of activity, with Information Technology standing out prominently in both cases. Generally speaking, all other categories have a similar percentage incidence in both indices.

Sector (weights) MSCI World S&P 500
Information Technology 23.68% 29.20%
Financials 15.36% 13.1%
Health Care 11.99% 12.30%

Industrials 10.73% 9.10%
Communication Services 7.44% 8.80%
Consumer Staples 6.52% 6.20%
Energy 4.46% 4.10%
Materials 3.90% 2.40%
Utilities 2.43% 2.30%
Real Estate 2.27% 2.20%

Note: The weights listed in the table refer to March 29, 2024.

Number of holdings

While the MSCI World Index boasts a diverse range of 1,465 constituents, the S&P 500 falls short with only 503 holdings. It may seem odd that the S&P 500 does not have exactly 500 stocks. However, our team has brought you one of the reasons behind this discrepancy. This is because there are companies in the S&P 500 that have multiple classes of shares, accounting for the additional stocks.

Top 10 holdings

Our team has gathered the top 10 holdings of each index, so the table confirms that they are pretty similar. However, each stock’s weights in the respective index differ.

S&P 500 MSCI World
Stocks Weights Stocks Weights
Microsoft Corp 7.04% Microsoft Corp 4.57%
Apple Inc 5.60% Apple Inc 3.88%
Nvidia Corp 5.02% Nvidia Corp 3.44% Inc 3.71% Inc 2.58%
Meta Platforms Inc Class A 2.40% Meta Platforms Inc Class A 1.66%
Alphabet Inc Cl A 2.00% Alphabet Inc Cl A 1.37%
Berkshire Hathaway Inc Cl B 1.72% Alphabet Inc Cl C 1.21%
Alphabet Inc Cl C 1.69% Eli Lilly, Co 0.97%
Eli Lilly, Co 1.40% Broadcom 0.91%
Broadcom 1.31% JP Morgan Chase 0.89%

Note: The weights listed in the table refer to March 29, 2023.

A pattern observed in the top 10 holdings is that the companies tend to be from the United States, so although the MSCI World is more geographically diversified, it still carries a significant relative weight (approximately 70%).

Nevertheless, it is crucial to recognize that past performance is not indicative of future returns, and these results may not persist indefinitely.

Is the MSCI World better than the S&P 500?

As you might suspect, there is no “better” index. It all comes down to your preferences and goals. The main difference is that the S&P 500 only includes US-based companies, whereas the MSCI World Index includes companies from 23 developed countries.

From the global financial crisis of 2007-09, the S&P 500 has outperformed the MSCI World Index. Still, there have been periods where it was the other way around.

It all depends on your perspective concerning the companies’ evolution in each index. Since all have a global presence, the correlation between the S&P 500 and the MSCI World Index will be pretty high. So, investing in both does not give proper diversification benefits.

Availability of ETFs

As you may already know, you cannot directly purchase an index. You need to buy a fund that tracks that index. Two types of funds that can track an index include exchange-traded funds (ETFs) and index funds.

S&P 500

With a larger number of companies in its index, it offers you the opportunity to diversify your investments further.

Additionally, you can choose from multiple exchange-traded funds (ETFs) that track the performance of the S&P 500 and MSCI World indices.

In summary, if you’re looking to expand your investment horizons, the MSCI World index provides a more comprehensive global perspective compared to the US-focused S&P 500, offering you the potential for enhanced diversification in your portfolio.
