VWCE tracks its index by sampling rather than full replication, so the holdings count above reflects what the fund actually holds, which is fewer than the number of constituents in the index (3,756 holdings vs. 4,264 index constituents as at 31 July 2026). Names in the index that the fund does not hold cannot overlap with any other fund.

Concentration & Sector Tilt
How top-heavy each fund is, and which sectors each one leans into. Sector weights are our own roll-up of the GICS sector on each holding in the issuer's holdings file, so they can differ slightly from the issuer's factsheet.
Top 10 is measured against the full fund, not rescaled to the equity sleeve, and each share class (for example Alphabet A and C) counts as a separate holding. Issuer factsheets that combine share classes and exclude cash and currency forwards from the denominator can show a figure about a point higher.
