A fund’s weight in a company is the share of the fund’s money held in that company’s shares. A weight of 5% in a fund worth £1 billion is about £50 million. Index funds hold companies in proportion to their size in the index, so the largest companies appear in many funds at similar weights.
The list above comes from holdings the fund issuers publish, each dated, and names the funds where Biogen Inc. is one of the ten largest holdings — the part of every fund page open to anyone. Some issuers publish only their largest ten, so a fund can hold Biogen Inc. without it appearing in any list here. When two funds both hold the same large companies, owning both can be closer to owning one than it looks: the comparison page measures that overlap when both funds publish enough of their holdings.
