Model Portfolio
A model portfolio is a pre-defined asset allocation template used by investment advisers to manage multiple client accounts consistently. It simplifies portfolio construction, rebalancing, and compliance documentation.
Definition
Model Portfolio —
A model portfolio is a pre-defined template of asset allocations — typically expressed as target weights across asset classes, sectors, or specific securities — that an investment adviser applies to a group of clients with similar investment objectives, risk tolerance, and time horizons. Model portfolios enable consistent, scalable portfolio management across a client base and simplify rebalancing, drift monitoring, and trade execution.
How model portfolios work
An adviser typically maintains a library of model portfolios representing different risk profiles or investment objectives:
| Model name | Equity | Fixed income | Alternative | Target client |
|---|---|---|---|---|
| Conservative | 30% | 65% | 5% | Preservation-focused, low risk tolerance |
| Moderate | 60% | 35% | 5% | Balanced growth and income |
| Growth | 80% | 15% | 5% | Long-term growth, higher risk tolerance |
| Aggressive | 95% | 5% | 0% | Maximum growth, longest horizon |
Clients are assigned to a model based on their Investment Policy Statement (IPS) and suitability profile. When the model is updated — due to market conditions, manager changes, or strategic shifts — the change is applied across all accounts in that model.
Benefits for compliance and operations
Consistency: All clients in the same model receive the same investment experience, reducing the risk of inadvertent disparate treatment.
Drift monitoring: Checking whether client accounts have drifted from the model target is easier to systematize than client-by-client analysis.
Documentation: The model's rationale, changes, and version history create an investment research record that supports examinations.
Trade efficiency: Block trades and model-level rebalancing reduce execution complexity and cost.
Model portfolios and IPS alignment
The Investment Policy Statement for each client specifies which model is appropriate and the allowable drift ranges before rebalancing is triggered. If a client's circumstances change — a liquidity event, risk tolerance shift, or change in time horizon — the adviser must evaluate whether the current model assignment remains appropriate.
Model portfolio changes and client notification
When an adviser makes a material change to a model portfolio, best practices include:
- Documenting the rationale for the change
- Assessing whether the change remains appropriate for all clients in the model
- Identifying any clients for whom the change is not appropriate and managing them separately
- Disclosing material strategy changes in client communications

Tax-loss harvesting is an investment strategy that realizes capital losses to offset capital gains, reducing taxable income. It requires careful attention to wash-sale rules under IRC § 1091.
Sharpe Ratio
The Sharpe ratio measures risk-adjusted return by dividing excess return (above the risk-free rate) by the standard deviation of returns. Higher is better: more return per unit of risk.

Registered investment advisers (RIAs) and broker-dealers are both regulated financial intermediaries, but they operate under different regulatory frameworks, compensation structures, and standards of care.
