About
A small instrument for a large question.
ETF Weight started with a simple observation: a portfolio can look diversified because it contains a global fund, while its country exposure is still concentrated in a handful of listed markets.
The goal is not to tell you that one country should have a particular weight. It is to make the difference visible, quantify it, and show the assumptions underneath.
Principles
- Show the residual. Cash and derivatives belong in the answer, not in a hidden normalisation.
- Date every dataset. A current-looking interface should not make stale holdings look live.
- License before import. Public visibility is not commercial reuse permission.
- No advice. The user brings the question. The tool does the arithmetic.
Who it is for
Curious long-term investors, students, journalists, product designers and anyone who wants to examine the gap between a portfolio's financial geography and the geography of the real economy.
Commercial reality
The initial catalogue uses US-listed reference funds with public SEC filings. A production UCITS catalogue needs a licensed holdings feed. That is documented as a decision, not hidden behind a generic “global ETF” claim.
