- As of Nov 5, 2026, ETFIQ can compare any two of 5,068 ETFs, and it measures overlap for 37,717 pairs, with 7.5% sharing over half of their weight.
In plain words
Compare two ETFs on the same few things: what each owns, costs, did against its benchmark over the same dates, how each trades, and how much of one is already in the other.
Start with the benchmark: two funds compare fairly only if they measure themselves against the same thing. Then compare fee, net assets, return and spread over matching windows, and overlap: 7.5% of 37,717 measured pairs share over half their weight. The compare tool puts two funds side by side with every window and date. Funds in different categories do different jobs, and a plain comparison can mislead.
Questions
- What do I compare first?
The benchmark each fund names. It sets what a fair comparison is.
- Can I compare funds in different categories?
You can, but they do different jobs. ETFIQ warns when categories differ.
- Where do I start?
The compare tool, with two tickers.
