Weights are from each issuer's most recent published file, dated between 2026-07-31 and 2026-09-05; the files arrive on different schedules, so the dates differ on purpose. 34 funds with a non-US mandate, ACWX, CORO, CWI and 31 more, file a row under the symbol MRK; those rows are left out of this page and of its counts, because in such a file a US symbol is usually the local exchange code of a different company. The JSON file and the holders index keep every raw row, 161 in all. The rows kept here appear in the same order in the JSON file for MRK and in the holders index. Look MRK up with an amount to see what a position in each fund holds of it in dollars.
