Quick Picks: Top 3 Global Indices for Managing Risk
Pressed for time? Here are the best choices for investors looking to manage portfolio risk through global diversification.

How We Chose the Best Global Stock Market Indices
Choosing the right index isn't just about picking the one with the highest returns last year. For risk management, the criteria are different. Your goal is to build a portfolio that can withstand shocks from any single country's economy or stock market. We based our rankings on three core principles:
- Geographic Diversification: How well does the index spread your investment across different countries and regions? An index heavily weighted towards one country is riskier than one that is globally balanced.
- Broad Market Coverage: Does the index include a wide range of company sizes (large, mid, and small-cap) and sectors? More stocks from more industries generally means less risk.
- Investor Accessibility: How easy is it for a typical retail investor to gain exposure to this index? We prioritized indices that are widely used as benchmarks for ETFs and mutual funds.
A Ranked List of Top Indices for Risk Management
Managing risk is about not putting all your eggs in one basket. These global stock market indices give you thousands of baskets spread all over the world.
#3. FTSE Global All-World Index
The FTSE Global All-World Index is a fantastic and highly popular choice for investors seeking broad global exposure. It’s a very close competitor to our top pick.
- Why it's good for risk management: This index tracks over 4,000 stocks in both developed and emerging markets. Its sheer size and scope mean that a problem in one company or even one country has a limited impact on the overall index performance. It automatically rebalances, ensuring you are always invested across the global economy's most significant players.
- Who it's for: This index is perfect for the long-term, set-it-and-forget-it investor who wants a single, simple solution for global equity exposure. If you want to own a piece of almost every public company that matters, this is a great way to do it.
#2. MSCI EAFE Index
The MSCI EAFE Index is a bit more specialized, but it serves a powerful purpose in risk management, especially for investors in North America.
- Why it's good for risk management: The acronym stands for Europe, Australasia, and the Far East. This index specifically excludes companies from the U.S. and Canada. This is its key strength for risk reduction. Many investors have a strong "home country bias," meaning most of their stocks are from their own country. The EAFE index provides a powerful tool to directly counter this by investing in over 800 large and mid-cap stocks across 21 developed countries outside North America. It helps you diversify away from a U.S.-heavy portfolio.
- Who it's for: This is a must-have for U.S. or Canadian investors who already have significant exposure to their home markets (like through an S&P 500 fund) and want to balance their portfolio internationally.
#1. MSCI ACWI Index
For my money, the MSCI ACWI is the undisputed king of global stock market indices for risk management. It offers the most complete and balanced snapshot of the global stock market in a single package.
- Why it's good for risk management: ACWI stands for All Country World Index. It captures the entire global opportunity set, covering nearly 3,000 stocks across 23 developed markets and 24 emerging markets. It represents about 85% of the free float-adjusted global market capitalization. By owning a fund that tracks this index, you are instantly diversified across dozens of countries, currencies, and economic cycles. The struggles of one region can be offset by the success of another, smoothing your returns over time. The International Monetary Fund often discusses how interconnected global markets are, and the ACWI reflects this reality.
- Who it's for: Any investor who wants a single, gold-standard benchmark for their entire global stock allocation. It’s the perfect core holding for a diversified portfolio. Whether you are a beginner starting with one fund or an expert building a complex portfolio, the MSCI ACWI serves as the ultimate foundation.
True diversification means investing beyond your own borders. Economic conditions can vary wildly from one region to another, and a global index helps protect you from localized downturns.

Beyond the Top 3: Other Indices to Know
While our top three cover most needs, some investors might want to get more specific with their risk management strategies.
MSCI Emerging Markets Index
This index focuses solely on countries with developing economies, like China, India, Brazil, and Taiwan. While emerging markets can be more volatile on their own, adding a small, dedicated allocation to them can sometimes improve a portfolio's overall risk-adjusted returns. They often grow at a different pace and respond to different economic factors than developed markets, providing unique diversification benefits.
Low Volatility Indices
Several providers, including MSCI and S&P, offer "minimum volatility" or "low volatility" versions of their main indices. For example, the MSCI ACWI Minimum Volatility Index selects stocks from the parent ACWI index that have historically shown lower price swings. This can be an effective strategy for conservative investors who want to stay invested in stocks but are particularly worried about sharp market downturns. The goal is to capture most of the market's upside with less of the downside.
Ultimately, using global stock market indices is a proven strategy for managing risk. By spreading your investments widely, you reduce your dependence on the fortunes of any single country. For a balanced, simple, and effective approach, the MSCI ACWI remains the top choice for building a resilient, world-class portfolio.
