Portfolio overlap
89 common holdings · ticker match on full official portfolios
How the shared part is computed: for each security held by both funds, only the SMALLER of the two weights counts — a stock at 5% in one fund and 1% in the other overlaps by 1%, not 5%. Summed over all 89 common holdings this gives 95.4%: buying both funds, roughly this share of your money buys the same stocks twice. Matching uses the ISIN of each security, as published by both issuers in their baskets.
