Most stock market indexes are unique, even if they seem on their surface to cover the same financial ground. The MSCI World Index and the FTSE All-World Index both show how the global stock market is performing. But they do it in their own ways. Knowing their similarities and differences can help you make decisions about your portfolio.

What is a stock market index?

A stock market index tracks the performance of a certain set of stocks. Those stocks may be grouped by company size, country, industry, or some other factor. The specifications can be narrow or broad. The list can be short or long. What matters is that the companies fit within the parameters outlined and those parameters remain consistent. Investors can’t invest directly in an index. But there are products, like exchange‑traded funds (ETFs), single investments that trade on stock exchanges and give exposure to a basket of assets, which aim to deliver investors the performance of a specified index, minus fees.

What is the MSCI World Index? What’s the FTSE All-World Index?
The MSCI World Index is a global stock market index that tracks 1,311 stocks across 23 countries, all of which are classified as developed markets. The FTSE All-World Index is a global stock market index that includes 4,264 stocks across nearly 50 countries, covering both developed and emerging markets.

How are the MSCI World Index and FTSE All-World Index similar?

  • Both indexes are market-capitalisation weighted, which means the largest companies have the largest weight in the index.
  • Because the world’s big companies tend to be technology oriented, both indexes currently lean toward technology giants, as of March 2026.
  • They both invest in large‑capitalisation and mid‑capitalisation companies, meaning well‑established businesses with large market values, as well as medium‑sized companies that are still growing.
  • The US, Japan, and the UK are currently the highest-represented countries in each index, as of March 2026.

How are the MSCI World Index and FTSE All-World Index different?

The key difference is in their approach to investing in developed markets (countries with more advanced economies and more mature capital markets) and emerging markets (developing nations transitioning toward advanced economies).

  • The MSCI World only invests in developed markets. So, it doesn’t include companies from China, India, and Brazil, for example.
  • The FTSE All-World tracks both developed and emerging markets. This broader scope means that it invests in many more companies from many more countries than MSCI World.

Which approach is better?

There have been years when the MSCI World has outperformed, and years when the FTSE All-World outperformed. Emerging markets tend to be more volatile than developed markets and may present more political and economic instability. On the other hand, they can also experience periods of impressive growth through trends such as rapid industrialisation, expanding middle-class consumption, and a younger population. So, the answer to which approach is “better” will be unique to each client’s goals and risk tolerance.

How can investors access each index?

While investors cannot buy an index directly, they can invest with exchange-traded funds that track them such as:

The Fund is invested in a particular geographical region, which might result in greater fluctuations in the value of the Fund than for a fund with a broader geographical investment mandate.
