China has no single index that plays exactly the same role the S&P 500 plays in the US, but the closest analog is the CSI 300: the 300 largest and most liquid mainland A-shares, run by China Securities Index Co. Below is the full map of the major benchmarks and how a US investor actually buys them.
Key takeaways
- The CSI 300 is the tightest "China's S&P 500" match: 300 large- and mid-cap A-shares from the Shanghai and Shenzhen exchanges, weighted by free-float market cap and reviewed twice a year.
- The SSE Composite is broader and less analogous (every stock on the Shanghai exchange), while ChiNext is Shenzhen's growth board, closer to the Nasdaq in spirit.
- For Hong Kong-listed Chinese giants, look at the Hang Seng Index (broad HK large-cap) and the HSCEI (mainland enterprises in HK).
- US investors reach these through ETFs: ASHR (CSI 300 A-shares), MCHI (broad MSCI China), FXI (HK-listed large caps), and KWEB (China internet).
- The honest risks are structural, not just volatility: VIE ownership, US delisting history under the HFCAA, state intervention, and capital controls. Read them before you size a position.
The main Chinese benchmark indices
Chinese equities trade across three venues (Shanghai, Shenzhen, and Hong Kong) with different share classes and different investor access rules, so no one index captures the whole market the way the S&P 500 captures US large caps. Here is how the major benchmarks line up.
| Index | What it covers | Closest US analog | How to access (ETF) |
|---|---|---|---|
| CSI 300 | 300 largest, most liquid A-shares on Shanghai + Shenzhen; free-float cap-weighted; launched April 2005 | S&P 500 | ASHR (Xtrackers Harvest CSI 300 China A-Shares) |
| SSE Composite | All A- and B-shares listed on the Shanghai Stock Exchange; cap-weighted, very broad | A Shanghai-only total-market gauge, loosely like a Wilshire | No clean US-listed pure play |
| ChiNext | Shenzhen growth board of younger tech and innovation names; wider daily price limits | Nasdaq / growth board | Limited US access; some broad China funds hold it |
| Hang Seng Index | ~80+ largest companies on the Hong Kong exchange, including many mainland giants | Broad HK large-cap benchmark | Broad HK/China funds |
| HSCEI (H-shares) | 50 mainland-linked enterprises listed in Hong Kong; 8% single-stock cap | China large-cap in HK | FXI overlaps heavily |
CSI 300: the closest analog
The CSI 300 is compiled by China Securities Index Co. and tracks the 300 largest and most liquid A-share stocks listed in Shanghai and Shenzhen, selected on market cap and liquidity and weighted by free-float. It launched in April 2005 and rebalances semi-annually. Financials, industrials, consumer, and, increasingly, technology dominate the weighting, which mirrors China's economic structure more than the tech-heavy S&P 500 does.
SSE Composite and ChiNext
The SSE Composite tracks every A- and B-share on the Shanghai Stock Exchange, so it is broader and noisier than a curated large-cap index and skews toward established banks, energy, and industrials plus the STAR Market for strategic tech. ChiNext, run by the Shenzhen exchange, is the growth board of younger technology and innovation companies with wider daily price limits, which is why it gets called China's Nasdaq.
Hang Seng and HSCEI
Many of the biggest Chinese companies list in Hong Kong rather than on the mainland, so the Hong Kong benchmarks matter. The Hang Seng Index is the broad Hong Kong large-cap gauge, and the Hang Seng China Enterprises Index (HSCEI) narrows to mainland-linked enterprises listed in Hong Kong, with a cap so no single name dominates.
How US investors access Chinese indices
You do not need a mainland brokerage account. Several US-listed ETFs give exposure, and they are not interchangeable. What you pick determines which market, which share class, and which sectors you own. Expense ratios below are as reported by the issuers and ETF databases in 2026; confirm the current figure before you buy.
| ETF | Tracks | Exposure | Expense ratio (approx.) |
|---|---|---|---|
| ASHR | CSI 300 Index | Mainland A-shares, held directly | ~0.65% |
| MCHI | MSCI China Index | ~600 names across A-shares, H-shares, and ADRs (broadest) | ~0.59% |
| FXI | FTSE China 50 | 50 largest HK-listed Chinese companies, state-owned tilt | ~0.74% |
| KWEB | CSI Overseas China Internet | Overseas-listed China internet (Alibaba, Tencent, PDD) | ~0.70% |
ASHR is the cleanest way to own the CSI 300 itself, since it buys the underlying A-shares directly rather than using derivatives. MCHI is the broadest single-fund China play. FXI concentrates on the largest Hong Kong-listed names and leans toward state-owned banks, insurers, energy, and telecoms. KWEB is a concentrated bet on Chinese internet platforms and behaves very differently from the others.
The honest risks
China exposure carries structural risks that go beyond ordinary market volatility, and they are worth understanding before you commit capital.
- VIE structures. Many China internet and tech companies that US investors buy (through ADRs and funds like KWEB) are held via variable interest entities. You own a shell, usually offshore, that holds contractual claims on the mainland operating company rather than direct equity. Chinese law has never fully blessed the structure, so enforceability is a genuine open question.
- Delisting risk. Under the Holding Foreign Companies Accountable Act, US-listed Chinese firms faced forced delisting if the PCAOB could not inspect their auditors for two straight years. That threat eased in December 2022 when the PCAOB gained inspection access and vacated its determinations, but the statute stands and access is political, so the risk can return.
- State intervention. Beijing can and does reshape entire sectors with little warning, as the 2021 crackdowns on tech and private tutoring showed. Regulatory shifts, not earnings, are often the biggest driver of returns.
- Capital controls and access limits. Foreign access to A-shares still runs through channels like Stock Connect and the QFII program, and currency movement in and out of China is controlled, which adds friction that does not exist in US markets.
Bottom line
If you want the single best "China's S&P 500," it is the CSI 300, and ASHR is the straightforward way to own it. If you want broad China in one ticker, MCHI does more of the job. Just size the position for the structural risks above, and treat it as a satellite rather than a core holding.

Frequently asked questions
What is China's equivalent of the S&P 500?
The closest analog is the CSI 300, which tracks the 300 largest and most liquid A-shares listed on the Shanghai and Shenzhen exchanges, weighted by free-float market cap and reviewed twice a year. Compiled by China Securities Index Co., it launched in April 2005. No single Chinese index plays exactly the same role the S&P 500 plays in the US.
How can a US investor buy the CSI 300?
US investors reach the CSI 300 through ASHR, the Xtrackers Harvest CSI 300 China A-Shares ETF, which buys the underlying A-shares directly rather than using derivatives. That makes ASHR the cleanest way to own the index. For broad China in one ticker, MCHI tracks about 600 names across A-shares, H-shares, and ADRs. You do not need a mainland brokerage account.
What are the structural risks of investing in Chinese indices?
The risks are structural, not just volatility. VIE structures mean you often own an offshore shell with contractual claims rather than direct equity. US delisting risk persists under the Holding Foreign Companies Accountable Act despite easing in December 2022. State intervention can reshape sectors with little warning, as the 2021 tech and tutoring crackdowns showed. Capital controls add friction absent in US markets.
What is the difference between the CSI 300 and the SSE Composite?
The CSI 300 is a curated index of 300 large- and mid-cap A-shares from both Shanghai and Shenzhen, making it the tightest S&P 500 match. The SSE Composite tracks every A- and B-share on the Shanghai exchange alone, so it is broader and noisier, skewing toward established banks, energy, and industrials plus the STAR Market. There is no clean US-listed pure play for the SSE Composite.
