MSCI Index and What It Measures

The MSCI Indexes are a measurement of stock market performance in a particular area. Like other indexes, such as the Dow Jones Averages or the S&P 500, it tracks the performance of the stocks included in the index. 

MSCI Indexes are used as the base for exchange-traded funds. The ETF duplicates the Index's stock holdings. That allows investors to profit from gains in the Index.

Similarly, Indexes are also the benchmarks that actively managed mutual funds use as bases. The exchange-traded funds follow the MSCI Indexes. Managed mutual funds try to outperform them by picking better stocks.

How They Work

MSCI selects stocks for its equity indexes that are easily traded and have high liquidity. The stocks must have active investor participation and be without owner restrictions. MSCI must balance accuracy and efficiency. It must include enough stocks to represent the underlying equity market. At the same time, it can't have so many stocks that ETFs and mutual funds can't mimic the index.

Each Index sums up the total value of all stocks' market capitalization. That's the stock price multiplied by the number of outstanding shares. The S&P 500, but not the Dow, uses the same methodology. Market caps are calculated in both U.S. dollars and in local currency. That gives you an idea of how the index is doing without the impact of exchange rates.

Each index is updated daily, Monday through Friday. Additionally, each index is reviewed quarterly and rebalanced twice a year. That's when its manager adds or subtracts stocks to make sure the index still accurately reflects the composition of the underlying equity market it measures.

For that reason, MSCI Indexes have the power to change the market. When an index is rebalanced, all the ETFs and mutual funds that track it must buy and sell the same stocks. Stocks that are added to the index usually find their share prices rising. The opposite happens to stocks that are dropped from an index.

What They Measure

MSCI has indexes for a variety of geographic sub-areas, as well as global indexes for stock categories such as small-cap, large-cap, and mid-cap. The four most popular track emerging markets, frontier markets, developed markets excluding the United States and Canada, and the world market.

MSCI Emerging Market Index

The Emerging Markets Index tracks the performance of stock markets in the following 26 developing countries: Argentina, Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Malaysia, Mexico, Pakistan, Peru, Philippines, Poland, Qatar, Russia, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey, and United Arab Emirates. The MSCI Kuwait Index will be included in the MSCI Emerging Markets Index beginning November 2020.

In June 2017, MSCI Inc. announced it was adding over 200 China A-shares. Those shares are listed in Shanghai and Shenzhen and denominated in yuan. As a result, all exchange-traded funds that track the MSCI index were forced to add those shares.

Saudi Arabia is also included in the Gulf Cooperation Council Country Index.

The index compiles the market capitalization of all companies that are listed in these countries' stock markets. The index is considered a good measurement of the stock performance of emerging markets.

MSCI Frontier Markets Index

The Frontier Markets Index tracks the stock markets of countries which are even more volatile than emerging markets. It was created in 2007. The countries in the Index are Bahrain, Bangladesh, Croatia, Estonia, Jordan, Kazakhstan, Kenya, Kuwait, Lebanon, Lithuania, Mauritius, Morocco, Nigeria, Oman, Romania, Serbia, Slovenia, Sri Lanka, Tunisia, and Vietnam. That also includes the West African Economic and Monetary Union. It consists of the following countries: Benin, Burkina Faso, Ivory Coast, Guinea-Bissau, Mali, Niger, Senegal, and Togo. Currently, the MSCI WAEMU Indexes include securities classified in Senegal, Ivory Coast, and Burkina Faso.

The following frontier countries are in their own standalone country indexes. They aren't included in the Frontier Market Index: Bosnia and Herzegovina, Botswana, Bulgaria, Iceland, Jamaica, Malta, Palestine, Panama, Trinidad & Tobago, Ukraine, and Zimbabwe. 

Frontier markets can also very profitable since they have lots of room for growth. The main risk is that they are very thinly traded. This makes them difficult to sell if the economy deteriorates. It also means they can more easily be manipulated by hedge funds. You need to understand the countries, their political systems, and their economic challenges. These countries are vulnerable to global shifts in trade, currency, and central bank policy changes.


The EAFE Index measures developed markets excluding the United States and Canada. EAFE stands for Europe, Australasia, and the Far East. It covers 85% of the market capitalization in each of the countries.

The MSCI EAFE Index consists of the following developed market country indices: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, and the United Kingdom.

MSCI World Index 

The World Index measures the market performance of large and mid-cap companies that have a global presence. It is often quoted by financial media to describe how the world's stock market is doing. It excludes stocks from emerging market countries, so it should be considered a developed world index.

It includes the following countries: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, United Kingdom, and the United States.

The MSCI AC World Index includes all the countries in the World and Emerging Markets Indexes. "AC" stands for "All Country."
