How much do your ETFs double up?
How much the ETFs in your portfolio own in common: the overlap between every pair, the companies they share, and what your combined portfolio really holds. Covers 326 ETFs using the issuers' published holdings.
How the overlap calculator works
For each pair of ETFs we look through to every company inside both funds. The overlap is the sum of the smaller weight of each shared company. For example, if CBA is 10% of one fund and 8% of the other, it adds 8% to the overlap. Two funds tracking the same index will show close to 100%; funds investing in different markets will show close to 0%.
A high overlap means you are doubling up: you pay two fees for much the same portfolio and may be more concentrated in a few large companies than you think. A low overlap means the funds add genuine diversification.
Holdings are as last published by each issuer and change over time. Some funds are shown through a stand-in index where the issuer does not publish full holdings; these are flagged. General information only, not a recommendation.
