These two products look similar on a feature list and are quite different in what they imply — commercially, operationally and in terms of the relationship between the client and the person trading.
The distinction that matters most
Copy trading involves no management mandate. The client chooses to follow a strategy and can stop whenever they like. MAM involves a manager acting on behalf of investors, which is a different relationship — and in many jurisdictions a relationship that carries regulatory implications for the manager.
Which should you launch first?
If your client base is retail, copy trading. It is easier for clients to understand, requires no manager onboarding, and works as a retention tool for clients who have stopped trading manually.
If you are courting professional managers with existing investor books, MAM — or PAMM — is what they will ask for, and not having it is what will stop them moving to you.
Many brokerages end up with both, serving different segments.
