How is ETF overlap calculated?

For every shared stock, WealthWise takes the smaller published weight in the two ETFs and adds those weights together.

Does the result cover every holding?

Not always. The estimate uses published top holdings and displays the analyzed coverage.

Do I need an account?

No. The public calculator is free without signup. An account is only needed to analyze your full portfolio.

How the calculation works

Published top holdings are loaded for each ETF.
Equivalent symbols are normalized.
For every shared stock, the smaller weight is retained.
Those weights form the pairwise overlap estimate.

Why it matters

Two ETFs with different names can hold the same large companies. Seeing that distinction separates your number of funds from your real diversification.

Frequently asked questions

Is high overlap always bad?

No. It may be intentional. The tool makes exposure visible; it does not recommend buying or selling.

Why is coverage not always 100%?

Public sources often provide only top holdings. WealthWise displays that limitation instead of presenting the estimate as exhaustive.

Are my symbols stored?

They are used for the public request and shareable URL. The page does not ask for identity or account data.
