How can I find ETFs whose portfolio intersects as much as possible with another ETF?

Question

I want to find alternatives to an ETF.

How can I find ETFs whose portfolio intersects as much as possible with this ETF?

Answer 1

There are various comparison tools available.

My broker offers a Mutual Fund/ETF Replicator tool that suggests alternatives with lower fees.

There are various internet tools as well. Here's an example of one at:https://www.etfrc.com/funds/overlap.php

It indicates that the SPY has 505 holdings, VOO has 512 holdings and that there are 503 overlapping constituents.

There are also correlation tools available that will compare the performance of ETFs over a designated time period.
