Once You've Picked a Manager, Here's How the Machinery Works

Choosing an external asset manager is frequently confused with choosing a financial adviser, and the two are not the same exercise. Some advisers do operate as a kind of pseudo external asset manager, using platforms built for financial advisers to run client money in a similar way. But the sequence that actually defines an EAM relationship, and where the value in it comes from, looks different once it is broken into its parts.

The order of decisions

The manager comes first, and the platform second. This is the reverse of how most people approach the bank channel, where the platform, meaning the bank itself, is usually chosen first and whoever sits behind the desk comes with it.

Choosing the manager. The selection generally rests on three things: trust in the individual or the firm, a track record that can actually be examined, and the manager's demonstrated ability to solve the specific, often unusual, problem the client has. This last point matters more than it sounds. A manager who is excellent at growing a diversified equity portfolio is not automatically the right choice for a client whose real need is structuring around a business exit or a concentrated single-stock position.

Choosing the platform. Only after the manager is chosen does the platform question arise, and it is a real choice, not a formality. Securities firms and fintech platforms, names like moomoo, Syfe, Revolut, and Endowus among others, offer sharp pricing on execution and custody. What they generally do not offer is the banking infrastructure that sits behind a private bank: Lombard lending, preferential financing rates, and the breadth of support services a private banking shelf provides. Neither platform type is universally better. The private bank sells infrastructure and lending capacity; the fintech platform sells low-cost execution.

In either case, the EAM's function is the same: either to compress the fee drag down to the lowest achievable level, or to justify a higher fee by delivering value that a lower-cost platform structurally cannot.

Discretionary, non-discretionary, or a fund

Once manager and platform are set, the mandate structure is the next decision. A discretionary portfolio management mandate, DPM, gives the manager authority to act without approving each trade. A non-discretionary mandate requires the manager to propose and the client to approve before anything moves. Some EAM shops also run their own fund, in which case the client is investing into a pooled vehicle the manager has built, rather than holding a segregated mandate. Which of the three is available depends on the specific shop, not on the client alone.

Not bound to a single manager

A detail that is often missed entirely: appointing a main asset manager does not lock a client into that one manager's own strategies. The main manager can, in turn, allocate a portion of the mandate into a specialist strategy run by a different manager entirely, consolidated under a single overall fee to the client. This layering, one manager selecting and blending in another's expertise on the client's behalf, is one of the more underused features of the EAM relationship, largely because most clients are not aware the option exists to ask for it.

How the fee actually splits

Two fee structures are standard in the industry, and they map onto the discretionary and non-discretionary mandates above.

Under a DPM mandate, the typical annual management fee sits around 1 percent, and the EAM separately retains retrocessions or commissions generated on trading revenue, trailer fees, and structured note fees. Under a non-discretionary arrangement, the EAM similarly earns from trading revenue, trailer fees, and structured product fees, but only executes at fee levels the client has agreed to in advance, with the client approving each transaction. This second structure is closer to how private banks and many financial advisers already operate.

It is worth being clear that fees exist in both structures. The comparison that actually matters is not "fee versus no fee," it is the same comparison that applies to a retail investor choosing between a fund charging 1.5 percent on a basic US equity exposure and a fund tracking the same broad market for a total expense ratio of 0.03 percent. The fee itself says very little. What it is buying, or failing to buy, says everything.

Where the EAM can build rather than just access

At this level, an EAM may be able to compare issuers or arrange a bespoke structure around a defined payoff, protection level, currency, and maturity. That does not make the outcome guaranteed: issuer credit risk, market conditions, liquidity, fees, and the precise legal terms still determine what the investor receives.

The network effect

Working through an EAM alongside a private bank generally opens both networks at once, the EAM's own manager relationships and the private bank's product shelf together. This combined access can surface managers and strategies that are not widely distributed, including quantitative and alternative funds. Access does not establish quality: performance history, drawdowns, liquidity, capacity, valuation, custody, fees, and operational due diligence still matter. Claims of high or uncorrelated returns should be tested against complete, independently verified data.
