Minho Investment Association| Updated September 25th, 2023

Indexes such as the S&P 500 and MSCI track the performance of a specific group of stocks or financial assets. They essentially serve as benchmarks to gauge the market’s overall performance or specific market sectors.

Investing in these types of indexes through ETFs and index funds replicating the respective index’s performance is possible. Through these investment vehicles, the investor achieves diversification across a broad set of companies or assets represented by the index.

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

Overview of the S&P 500 and the MSCI World

The Standard & Poor’s 500, known as the S&P 500, is one of the primary indices in the United States. It comprises 500 large-cap companies listed on the U.S. stock exchange, representing various sectors of the economy. Therefore, it is used to indicate the performance of the U.S. stock market as a whole.

Morgan Stanley Capital International, known as MSCI, is a financial services company that provides a wide range of global market indices. This index tracks the performance of large and mid-cap company stocks in 23 developed markets worldwide.

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 69.91%
Japan 6.13%
United Kingdom 3.94%
France 3.31%
Canada 3.14%
Others 13.57%

Note: The weights listed in the table refer to August 31, 2023.

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 22.22% 28.20%
Health Care 14.68% 13.20%
Financials 12.68% 12.50%
Consumer Discretionary 11.01% 10.60%
Industrials 10.89% 8.40%
Communication Services 7.26% 8.80%
Consumer Staples 7.25% 6.60%
Energy 4.87% 4.40%
Materials 4.09% 2.50%
Utilities 2.65% 2.40%
Real Estate 2.39% 2.40%

Note: The weights listed in the table refer to August 31, 2023.

Number of Holdings

While the MSCI World Index boasts a diverse range of 1,518 constituents, the S&P 500 falls short with only 505 holdings. It may seem odd that the S&P 500 has 505 stocks instead of 500. However, our team has brought you the reason behind this discrepancy. This is because there are 5 companies in the S&P 500 that have multiple classes of shares, accounting for the additional 5 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. For example, while Apple has a weight of 5.20% in the MSCI World, it reaches 7.05% in the S&P 500.

S&P 500 MSCI World
Stocks Weights Stocks Weights
Apple Inc 7.05% Apple Inc 5.20%
Microsoft Corp 6.68% Microsoft Corp 4.05% Inc 3.40% Inc 2.23%
Nvidia Corp 2.97% Nvidia Corp 2.13%
Alphabet Inc Cl A 2.16% Alphabet Inc Cl A 1.42%
Tesla Inc 1.96% Alphabet Inc Cl C 1.29%
Alphabet Inc Cl C 1.87% Tesla Inc 1.29%
Meta Platforms Inc Class A 1.81% Meta Platforms Inc Class A 1.15%
Berkshire Hathaway Inc Cl B 1.73% Berkshire Hathaway Inc Cl B 0.82%
Eli Lilly Cor 1.25% Exxon Mobil Corp 0.79%

Note: The weights listed in the table refer to Aug 31, 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 69%).

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

The S&P 500 is such a renowned index that it is traded worldwide, leading to an almost endless supply of ETFs replicating it. Therefore, our team has gathered a selection to showcase in this article.

By investing in the MSCI World index, you can benefit from broader global diversification across various geographies (and sectors). As such, this index gives you direct exposure to international markets beyond the US, contrary to the 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.
