Manager selection

Select external investment managers through documented strategy, team, performance, risk, operations, terms and portfolio-fit assessment.

Quick answer

Manager selection is the process of identifying, diligencing, approving and sizing external investment managers for a portfolio. It combines investment due diligence with operational due diligence and evaluates whether the strategy, team, process, track record, risks, capacity, terms and reporting fit the investor's mandate.

Use the worked example

Meaning and transaction use

An SEC filing describes a systematic manager-selection process with manager ratings followed by separate investment and operations due diligence for qualifying managers. [S1]

The same filing reviews organisation, investment process, portfolio construction, financing, fees, track record, loss history, references, controls and service providers. [S1]

Another SEC filing describes quantitative screening, qualitative interviews and ongoing process monitoring rather than selecting from a few strong years. [S2]

Worked example

Illustrative selection funnel only. Assume 80 managers screened, 20 advanced to initial review, eight completed full diligence and three were approved.

Scroll the table horizontally to view all columns.

Initial-review rate20 / 8025.0%
Full-diligence rate8 / 8010.0%
Approval rate3 / 803.8%
Approval from full diligence3 / 837.5%

The illustrative funnel approves three managers, equal to 3.8% of the screened universe.
