SD-05.11 — Completion Portfolio Management

Business Domain: BD-05 Portfolio Management (Front office) · Applies: BOTH

Purpose

Closes the gap between a portfolio’s aggregate exposures and its intended total-portfolio or liability target — the completion portfolio. When a fund is run through many managers, the managers — each unable to see the others’ books — leave the total portfolio with unintended factor, sector, region and currency tilts; when a pension’s matching assets do not perfectly track its liability, a gap remains. A completion portfolio is the overlay built to close that structural gap. It is a distinct capability from SD-05.4 Overlay & Hedging: an overlay shapes exposures and is judged on hedge effectiveness; a completion portfolio closes a gap against a target and is judged against that target.

Service Operations

Measure the aggregate exposure — measure the total portfolio’s factor, sector, region and currency exposure, working off the managers’ benchmark exposures so the completion does not offset their active positions.
Identify the exposure gap — the difference between the aggregate exposure and the total-portfolio or liability target.
Design the completion portfolio — the overlay of futures, swaps and securities that closes the gap.
Manage the liability-completion variant — for a liability-driven investor, close the gap between the liability cash flows and the matching assets.
Maintain and rebalance the completion portfolio — keep the completion aligned as the manager line-up and the target move.
Measure completion effectiveness — measure the residual gap against the liability or total-portfolio target.

Inputs and outputs

Inputs: the manager line-up’s aggregate exposure and the exposure gap identified by SD-05.10; the total-portfolio target (SD-01.6) or liability target (SD-01.7); derivative and market data.
Outputs: the completion portfolio and the completion-effectiveness report — feeding BD-06 (which executes the completion trades) and BD-09.

Entities

Consumes: Portfolio / Mandate (E-03), Benchmark / Index (E-10), Risk Measurement (E-19, risk_type = market for the aggregate factor and exposure measures); the derivatives entities (DR-NN) for the completion instruments; the SD-01.6 total-portfolio target; the SD-01.7 liability target; the manager line-up’s aggregate exposure and the exposure gap identified by SD-05.10.
Owns: none — the completion portfolio is recorded as holdings (E-04).

Standards

No external standard governs completion management. It is an established practitioner discipline — the liability-completion and multi-manager-exposure-completion variants are documented by the major overlay and LDI providers.

Open extensions

The boundary with SD-05.4 — both use overlay instruments; completion is measured against a liability or total-portfolio target, not hedge effectiveness.
The interaction with SD-05.10 (the source of the gap) and SD-01.6 / SD-01.7 (the source of the target).
