China ETF Correlation Calculator
ETF Correlate is a free tool for measuring how China-listed ETFs move together. Pick any two funds — CSI 300, ChiNext, a sector ETF, gold, or government bonds — and get the Pearson correlation coefficient of their daily returns, computed from recent market data. Add more funds to see the full correlation heatmap. No sign-up, no download.
Why correlation matters for China ETFs
Most broad A-share ETFs move together because they share the same domestic equity cycle, so holding several of them adds little diversification. Correlation makes that visible: two funds with r near 0.95 are effectively one bet, while a pair near zero genuinely diversify. Checking correlation before you add a holding is the quickest way to tell whether it brings something new or just more of the same.
How the tool calculates it
The tool fetches recent daily closing prices for each ETF you select, converts them to daily returns (the percentage change from one day to the next), and computes the Pearson correlation coefficient on those returns. Using returns rather than raw prices is important: price levels trend upward over time and make almost any two funds look correlated, while returns reveal the real day-to-day co-movement.
Pairs investors check most
Common comparisons include CSI 300 vs ChiNext (broad large-cap vs growth), equity vs a 10-year treasury bond ETF (to test a stock-bond hedge), and equity vs a gold ETF (a classic diversifier). The tool also shows a color heatmap across a whole basket so you can spot which holdings cluster together and which stand apart.
Free, with no account
There is nothing to install and no sign-up. Open the tool, pick your ETFs from the curated list or type any 6-digit code, choose a lookback period, and read the result. Data is delayed and provided for informational purposes only — this is a research tool, not investment advice.
Frequently asked questions
Which China ETFs can I compare?
Any China-listed ETF with a 6-digit code. The picker includes a curated list of liquid funds, and you can type any other code (e.g. 510300, 159915, 518880) into the custom box.
Is the correlation based on prices or returns?
Returns. The tool computes the Pearson correlation on daily returns, which is the statistically correct way to measure how two funds move together.
Is it really free?
Yes — the tool is completely free with no account and no limits hidden behind a paywall.
