Daily portfolio composition
The operational heart of a multi-manager ETF is the daily PCF. Every trading day in the US, an aggregated PCF is delivered to the market and to National Securities Clearing Corporation (NSCC). That file represents the ETF as a single, cohesive portfolio even though it may be made up of multiple independent sleeves.
This is where complexity increases materially.
Each sub-adviser delivers its holdings independently for pricing and create/redeem activity. Those holdings must be validated, priced, and assembled into a single portfolio. In some cases, the same security may be held by more than one manager. Those positions must be aggregated correctly, while independently “tagged” to each manager by the administrator (a process that is invisible to the market).
When a creation or redemption order arrives – whether in-kind, cash-in-lieu, or involving substitutions – the activity must be translated into precise instructions for the correct sub‑adviser. If the securities involved belong to Manager A’s sleeve, those deliveries and settlements must be directed exclusively to Manager A’s custody account, not Manager B’s. Each manager operates with unique delivery instructions, segregated accounts, and distinct settlement workflows.
From the market’s perspective, this all happens seamlessly. Internally, however, every line item is tagged back to its originating manager. Positions, trades, settlements, and accounting are tracked discretely across the full lifecycle of the transaction. This is not a manual process. It must be automated, scalable, and auditable.
