Discretionary fund management (DFM)
A discretionary fund manager makes investment decisions within an agreed mandate, without seeking approval for every trade. Eligibility and suitability depend on individual circumstances and tax treatment depends on personal circumstances and may change.
A DFM can be useful where a portfolio needs continuing oversight, a defined investment process and coordination with a broader financial plan. Delegating decisions does not remove the need to understand the mandate, costs, risks or the manager’s role.

Within our HNW investment planning advice, we compare discretionary management with advisory and self-directed approaches. Eligibility and suitability depend on individual circumstances, while tax treatment depends on personal circumstances and may change.
Definition
Discretionary fund management is an investment service in which a professional manager selects and changes investments within an agreed client mandate.
What does discretion mean in practice?
The client agrees objectives, risk parameters, permitted investments and any restrictions. The manager can then rebalance or make trades within that framework, allowing decisions to be made without waiting for approval on each occasion.
Discretion is not a promise of outperformance. It is a method of implementation and governance, and its value depends on the quality of the process, communication and oversight.
How should you build an appropriate mandate?
A robust mandate reflects time horizon, capacity for loss, income requirements, ethical preferences, currency needs and any legacy holdings that must be retained. It should also identify liquidity needs and the circumstances that would trigger a review.
For complex families, the mandate may need to account for trusts, business interests, pensions, philanthropy and different objectives between family members. Clear documentation reduces the risk of a portfolio drifting away from its purpose.
How should you assess a discretionary manager?
We consider the investment philosophy, research, asset allocation, portfolio construction, risk controls, reporting and service model. Costs should be transparent across management, advice, platforms, funds and dealing, not viewed as a single headline number.
Past performance needs context and cannot predict future returns. A manager’s willingness to explain decisions, acknowledge uncertainty and adapt to changed circumstances is often as important as the process on paper.
How should you review the management relationship?
A DFM relationship works best when there is a shared review rhythm and a clear division of responsibilities between the manager, financial planner, custodian and client. We monitor whether the portfolio remains aligned with the plan rather than judging every decision in isolation.
If objectives, family circumstances or spending needs change, the mandate should change too. A periodic review can identify excess cash, unintended concentration, unsuitable risk or an approach that no longer represents good value.

Frequently Asked Questions
Does a DFM guarantee better returns?
No. A DFM offers delegated investment management, not a guaranteed return or protection from loss.
Can I set restrictions for a DFM?
Usually. Restrictions can cover values, sectors, ethical preferences, liquidity and legacy holdings, subject to the manager’s service and practical limits.
How is a DFM different from advice?
An adviser helps define objectives and recommendations. A discretionary manager implements investment decisions within an agreed mandate; services may also be combined.
How often should a DFM mandate be reviewed?
Review timing depends on the plan, but it should be revisited when objectives, finances, family circumstances or market needs change.
