Questions people ask

Is Boston Partners Securities an ETF authorized participant (AP)?

Yes. Boston Partners Securities LLC is listed as an AP for 132 US ETFs in the Form N-CEN period ending May 31, 2026, and created or redeemed shares in 0 of them.

Where do these figures come from?

From item E.2 of each ETF’s latest Form N-CEN, which names its APs and the dollars each created and redeemed. ETFIQ groups the rows by Boston Partners Securities’s CRD, SEC file number and LEI, never by the name as typed.

Method

Boston Partners Securities LLC is identified by CRD 2998, SEC file number 8-15648. It is on the SEC’s list of active broker-dealers dated Oct 1, 2026 as BOSTON PARTNERS SECURITIES, L.L.C.. Funds filed its name 1 way; every spelling is in dealers.json. Every row is one authorized participant (AP) listed in item E.2 of an ETF’s latest Form N-CEN, with the dollars of the fund’s shares it purchased from the fund (created) and redeemed in the fund’s reporting period, as filed. A fund’s period is its own fiscal year, or less where the filing says so, so a firm’s total adds periods that end on different days. Rows are grouped into firms by the identifiers each row carries: the CRD number first, the SEC file number and LEI where the CRD is missing or typed wrong, never by name. 71 of 75,056 rows carry a CRD their file number and LEI place on another firm, and are counted there.

The rest of the method

A firm’s name is its registration on the SEC’s list of active broker-dealers where it is on it. Spot crypto and commodity trusts and ETNs file no N-CEN and are not here.
