Investing in emerging markets used to be simpler. You bought a broad fund, crossed your fingers, and watched the growth of the "BRIC" nations. But then China's domestic market grew too big to ignore, and things got complicated.
Honestly, if you've looked at your brokerage statement lately and wondered why your emerging markets fund behaves so strangely, the answer probably lies in a mouthful of a term: the FTSE Emerging Markets All Cap China A Inclusion Index.

It sounds like something only a quant in a basement would care about. In reality, it is the invisible engine behind billions of dollars in retirement accounts. It basically dictates how much "real" China you actually own.
What is this index, really?
Most people think "China" is just one big bucket of stocks. It isn't. For decades, international investors mostly bought Chinese companies listed in Hong Kong (H-shares) or New York (N-shares). Think Alibaba or Tencent.
But the "A-shares"—the companies listed on the mainland in Shanghai and Shenzhen—were largely locked away. They were the forbidden fruit of the financial world.
The FTSE Emerging Markets All Cap China A Inclusion Index was built to solve this. It is a transition tool. It blends the standard emerging markets universe (Brazil, India, Mexico, etc.) with a specific, calculated dose of those mainland Chinese A-shares.
Why "All Cap"? Because it doesn't just look at the giants. It includes small-cap and mid-cap companies, giving a much more granular look at the Chinese economy than the top-heavy indices of the past. As of early 2026, we are seeing this index manage a massive universe of over 4,800 constituents.

The quirk of "Inclusion Factors"
Here is where it gets kinda technical but stay with me. You can’t just dump all of China into an index overnight. If FTSE Russell did that, the sheer size of the Chinese market would swamp everything else. It would turn an "Emerging Markets" fund into a "China and Friends" fund.
To prevent this, they use an inclusion factor.
Back in 2019, FTSE Russell started including China A-shares at a fraction of their total weight. They started with 25% of their "investable" market cap. The FTSE Emerging Markets All Cap China A Inclusion Index tracks this gradual handshake.
Currently, the index reflects the aggregate quota and accessibility available to international investors via the Northbound Stock Connect program. It's a moving target. As China opens its doors wider—or closes them, depending on the regulatory mood—this index adjusts.
Why the "All Cap" part matters in 2026
If you only track large-cap stocks, you're mostly buying state-owned banks and massive energy companies. That’s fine if you want stability, but it’s not where the "new" China lives.
The All Cap version of the index pulls in the "ChiNext" and "STAR" market stocks. These are the tech disruptors, the biotech startups, and the green energy firms. By including small and mid-caps, the FTSE Emerging Markets All Cap China A Inclusion Index captures the volatility—and the potential—of the actual Chinese consumer economy.
For example, look at the sector breakdown. While technology remains a titan at nearly 30% of the weight, the inclusion of A-shares brings in a heavy dose of industrials and consumer staples that you just don't get with offshore listings alone.
The Vanguard Connection
You can't talk about this index without mentioning Vanguard. Their massive Emerging Markets Stock Index Fund (VWO) tracks this specific FTSE index.
With over $100 billion in assets, VWO's move to this index years ago was a watershed moment. It meant that millions of retail investors were suddenly, and perhaps unknowingly, becoming owners of mainland Chinese companies like Kweichow Moutai (the world's most valuable spirits company) or Contemporary Amperex Technology (CATL), the battery giant.
The "Ex-China" debate
It's not all sunshine. Lately, there’s been a massive surge in "Ex-China" emerging market funds. People are worried about geopolitical friction and regulatory crackdowns in Beijing.
Some investors feel the FTSE Emerging Markets All Cap China A Inclusion Index has too much China. They argue that when one country makes up roughly 25-30% of an "Emerging" index, you lose the benefits of diversification.

But here is the counter-argument: can you really claim to be invested in emerging markets if you ignore the second-largest economy on Earth? Probably not. This index is for the pragmatist. It acknowledges that China is too big to skip but too complex to swallow whole.
Practical next steps for your portfolio
If you are holding a fund that tracks this index, you need to be aware of the "rebalancing" act.
- Check your concentration. Look at your total portfolio. If you have a broad "Total World" fund AND a fund tracking this FTSE index, you might be "double-dipping" on Chinese tech more than you realize.
- Monitor the inclusion level. FTSE Russell periodically reviews the inclusion factor. If they move from the current partial inclusion toward "Full Inclusion," your exposure to China A-shares will jump significantly.
- Evaluate the "All Cap" volatility. Small-caps in China are a wild ride. If you have a low risk tolerance, the "All Cap" version of this index might be saltier than you're comfortable with compared to a standard Large-Cap index.
- Understand the tax drag. Because these funds deal with multiple jurisdictions and withholding taxes (like the US RIC tax rates mentioned in FTSE's own documentation), the "Net Tax" version of the index is what actually determines your take-home returns.
The FTSE Emerging Markets All Cap China A Inclusion Index isn't just a list of stocks. It's a bridge between the old way of investing in "foreign" markets and the new reality of a China-centric financial world. Whether you love the exposure or fear the risk, understanding this index is the only way to truly know what's inside your portfolio.
