CFP investment planning: returns, risk and allocation
Evaluate an investment against the household’s goal, time horizon, liquidity and ability to bear loss. Return calculations describe performance; they do not establish whether the investment fits the client.
The decisions to learn first
Holding-period return
- Working rule
- (Ending value - beginning value + income) ÷ beginning value
- Boundary
- State how external cash flows are handled.
Compound growth
- Working rule
- Beginning value × (1 + r)^n
- Boundary
- Assumes a constant stated rate with no external flows.
Diversification
- Working rule
- Spread exposure across different investments
- Boundary
- Does not eliminate all market risk.
Rebalancing
- Working rule
- Restore the intended allocation
- Boundary
- Consider taxes, costs and the purpose of the target.
Where this fits in the CFP exam
Investment Planning is approximately 17% of the exam. The domain spans vehicles and taxation, risk, market cycles, return measurement, valuation, allocation, diversification and portfolio analysis.
Selected official topic references: D.28, D.30 and D.31.
Practise here: Risk constraints, holding-period return and basic allocation principles.
Continue your preparation: Valuation, market cycles, vehicle taxation and investment strategies require additional work. Use the portfolio note for a rebalancing application.
Separate willingness, capacity and required return
Willingness describes how the client feels about uncertainty. Capacity depends on the financial consequences of a loss. A client who enjoys risk may still have little capacity in an account earmarked for next year’s tuition.
Required return is a planning output, not a promise that markets will deliver it. If the target return is incompatible with constraints, revisit the savings amount, goal size or deadline. Do not solve an infeasible plan merely by adding risk.
- 1
Goal
Specify amount, date and whether the goal is flexible.
- 2
Constraints
Identify liquidity, taxes and the consequence of loss.
- 3
Portfolio
Compare feasible allocations and explain the tradeoff.
Separate return measurement, diversification and allocation
A holding-period return includes the change in value and distributions relative to the starting investment. An average return is a different measure: an arithmetic average summarizes observations, while a compounded return describes the effect of sequential growth. Select the measure requested instead of treating all percentages as interchangeable.
Diversification spreads exposure, but the number of holdings alone does not establish it. Several funds can hold similar securities and respond to the same risks. Allocation concerns how exposure is distributed across asset categories in relation to goals, time horizon and tolerance and capacity for loss.
Rebalancing restores a chosen allocation after values move. It can involve trades or directing new cash, and taxes and costs may affect implementation. A target allocation is a planning input, not evidence that the chosen target fits every client.
Worked example: a zero average can still leave a loss
Assume an investment begins at $100, rises 20% in year one and falls 20% in year two, with no deposits, withdrawals or distributions. It grows to $120, then falls to $96. The two-year cumulative return is negative 4%, even though the arithmetic average of the two annual returns is zero.
The second percentage applies to a different base. This is why adding percentages or using a simple average can answer the wrong question. A return calculation should preserve the sequence and identify which cash flows belong in the calculation.
The same discipline matters when comparing alternatives. Historical return alone does not establish future performance, liquidity or suitability for a dated goal. Explain which client constraint would rule out an otherwise attractive-looking investment before choosing it.
Worked example: apply the rule
An original teaching example. All numerical assumptions are stated; this is not a released CFP Board question.
Original worked example
An investment begins at $50,000, pays $1,000 of cash income and ends at $52,000. Assume no contributions, withdrawals, fees or taxes. What is the holding-period return?
- 1Price gain = $52,000 - $50,000 = $2,000.
- 2Total return dollars = $2,000 + $1,000 = $3,000.
- 3Return = $3,000 ÷ $50,000 = 6%.
6% for the stated holding period.
Watch for: Ignoring income and reporting only the 4% price change, or calling a multi-year holding-period return an annual rate.
Change one fact: can you still solve it?
Attempt this original variation before revealing the answer. Explain which assumption changed and why it matters.
Try it
A holding-period return is 6%, but the holding period was two years. Can you call it a 6% annual return? Assume no external cash flows.
Reveal answer and reasoning
No. The equivalent compound annual rate is about 2.96%.
Solve (1 + r)² = 1.06, so r = √1.06 - 1. A holding-period measure must be matched to its period. Dividing by two gives only an approximation.
Questions about this topic
Does diversification guarantee no loss?
No. Diversification can reduce concentration, but a diversified portfolio can still lose value. The allocation must also fit the goal’s time horizon and risk constraints.
How much of the exam does this topic represent?
