Concentration in ETFs: the stocks that dominate the funds

An ETF is meant to be the opposite of a single-stock bet. For broad world funds that holds — even the largest position stays below five percent. Sector and theme funds are a different matter: there, one company regularly carries a fifth of the fund or more. Hold two of them and the same stock may sit in your portfolio twice without you noticing.

This page computes both from the holdings data of our fund coverage: where single names carry unusual weight, and how widely a stock is spread across indices in the first place.

The largest single weights

For each stock, the fund in our coverage where it carries the most weight. Broad world funds do not appear here — high single weights arise in sector and theme funds.

How widely the names are spread

Number of indices a stock sits in. Share classes and currency tranches of the same index count once. Note: measured against our fund coverage, which is unevenly distributed across providers — European blue chips are better represented in it than they are in the world market. The order therefore says something about our coverage, not about the market.
