CFA Level 3 Performance Measurement: notes and free practice
CFA Level 3 Performance Measurement distinguishes return measurement, attribution and appraisal. Calculate performance consistently, explain its sources relative to an appropriate benchmark, and assess whether the result reflects relevant risk and skill.
The key ideas, at a glance
Choose a fair comparison
Read the visual, then follow the worked example below. Use the stated case assumptions.
Illustrative worked case
Do the benchmark exposures match the strategy?
Domestic small-cap mandate
Evaluate a mandate-consistent comparison
Global large-cap benchmark
Reassess size and geography before judging skill
The case’s benchmark mismatch can distort appraisal. Matching a benchmark does not itself establish manager skill.
| Concept | Rule or decision | Common mistake |
|---|---|---|
| Choose a fair comparison | A benchmark should represent the mandate before performance is known. | Choosing a weak benchmark after seeing returns manufactures apparent outperformance. |
| Separate allocation and selection | Use one stated attribution convention consistently. | A single sector’s allocation effect is not the entire portfolio’s active return. |
| Read downside evidence | A ratio depends on its return definition, horizon and risk denominator. | Short histories and stale valuations can flatter risk-adjusted metrics. |
| Investigate the manager | Combine process evidence with returns and firm-level reporting controls. | GIPS verification does not guarantee a particular composite’s performance or future returns. |
01Choose a fair comparison
A benchmark should represent the mandate before performance is known.
Watch for: Choosing a weak benchmark after seeing returns manufactures apparent outperformance.
02Separate allocation and selection
Use one stated attribution convention consistently.
Watch for: A single sector’s allocation effect is not the entire portfolio’s active return.
03Read downside evidence
A ratio depends on its return definition, horizon and risk denominator.
Watch for: Short histories and stale valuations can flatter risk-adjusted metrics.
04Investigate the manager
Combine process evidence with returns and firm-level reporting controls.
Watch for: GIPS verification does not guarantee a particular composite’s performance or future returns.

- Question 1 of 10Level III common-core samplePerformance MeasurementMultiple choice
Case facts
Use Brinson-Fachler allocation: (portfolio weight - benchmark weight) × (sector benchmark return - total benchmark return). Weights are 40% and 30%; returns are 12% and 7%.
What is this sector’s allocation effect in percentage points?
Answer and explanations
The effect is (0.40 - 0.30) × (12% - 7%) = 0.50 percentage points.
Review the method- A - correct: The effect is (0.40 - 0.30) × (12% - 7%) = 0.50 percentage points.
- B: 1.20 percentage points omits the total benchmark return adjustment in the specified convention.
- C: 5.00 percentage points is the return difference before multiplying by the weight difference.
- Question 2 of 10Level III common-core samplePerformance MeasurementMultiple choice
Case facts
Define selection effect as benchmark weight × (portfolio sector return - benchmark sector return). The weight is 25%; the returns are 14% and 10%.
What is the selection effect in percentage points?
Answer and explanations
The specified selection effect is 0.25 × (14% - 10%) = 1.00 percentage point.
Review the method- A: 4.00 percentage points ignores the sector weight.
- B - correct: The specified selection effect is 0.25 × (14% - 10%) = 1.00 percentage point.
- C: 3.50 percentage points uses portfolio return alone instead of the return difference.
- Question 3 of 10Level III common-core samplePerformance MeasurementMultiple choice
Case facts
A strategy earns 10% against a target return of 4%. Its downside deviation relative to that target is 5%, all measured over the same period.
What is the strategy’s Sortino ratio for this period?
Answer and explanations
The Sortino ratio is (10% - 4%)/5% = 1.20 with the stated target and risk measure.
Review the method- A: 2.00 divides total return by downside deviation without subtracting the target.
- B: 0.80 divides the target by downside deviation, not excess return.
- C - correct: The Sortino ratio is (10% - 4%)/5% = 1.20 with the stated target and risk measure.
- Question 4 of 10Level III common-core samplePerformance MeasurementMultiple choice
Case facts
A portfolio’s value rises to a peak of 125, falls to 100 and later recovers. Ignore external cash flows.
What is the drawdown magnitude from that peak to trough?
Answer and explanations
Drawdown magnitude is (125 - 100)/125 = 20%, measured relative to the prior peak.
Review the method- A - correct: Drawdown magnitude is (125 - 100)/125 = 20%, measured relative to the prior peak.
- B: 25% uses the trough as the denominator rather than the peak.
- C: 5% does not represent the 25-unit loss relative to the 125-unit peak.
- Question 5 of 10Level III common-core samplePerformance MeasurementMultiple choice
Case facts
A manager chooses the worst-performing index in the investment universe after the reporting year ends.
Which benchmark requirement is most clearly violated?
Answer and explanations
Selecting the index after observing performance violates the requirement to specify an appropriate benchmark in advance.
Review the method- A: A benchmark need not outperform the portfolio; it provides a relevant comparison.
- B - correct: Selecting the index after observing performance violates the requirement to specify an appropriate benchmark in advance.
- C: Exact inclusion of every portfolio security is not the key issue in this case.
- Question 6 of 10Level III common-core samplePerformance MeasurementWritten response
Case facts
An attribution report shows +0.4 percentage points from allocation, -0.2 from selection and +0.1 from interaction. All effects use the same convention.
Calculate total active return and identify the largest positive contributor.
Model answer and self-review rubric
The effects sum to +0.3 percentage points. Allocation is the largest positive contributor at +0.4; selection detracts. This reconciles the effects but does not by itself establish repeatable skill.

- Question 7 of 10Level III common-core samplePerformance MeasurementWritten response
Case facts
A private-asset fund reports smoothed quarterly valuations and a high risk-adjusted return ratio compared with daily-priced public assets.
Explain one comparability problem and recommend an additional check.
Model answer and self-review rubric
Smoothed valuations may understate volatility or downside deviation, inflating the ratio. Examine valuation methods, economic exposures and stress-period cash flows or drawdowns before comparing the funds.

- Question 8 of 10Level III common-core samplePerformance MeasurementWritten response
Case facts
A committee hires a manager solely because the last two years show top-quartile returns. The investment team and ownership have changed.
Recommend two due-diligence actions before final appointment.
Model answer and self-review rubric
Review whether the current team can execute the documented strategy and assess ownership incentives and operational controls. Determine whether historical results are representative of today’s process and resources.

- Question 9 of 10Level III common-core samplePerformance MeasurementWritten response
Case facts
A salesperson states that firm-wide GIPS verification guarantees every composite return is accurate and guarantees future outperformance.
Identify the two misleading assurances.
Model answer and self-review rubric
Firm-wide verification is not assurance about the performance of any specific composite, and neither GIPS compliance nor verification guarantees future investment returns. Review the relevant report and disclosures.

- Question 10 of 10Level III common-core samplePerformance MeasurementWritten response
Case facts
A pension’s objective is to meet inflation-linked domestic liabilities. Its sole performance yardstick is an unrelated foreign equity index.
Explain why a liability-based comparison adds useful information.
Model answer and self-review rubric
The equity index does not measure how assets keep pace with the liabilities’ currency and inflation exposures. A suitable liability-based comparison shows funding-related performance that an unrelated asset index can hide.

Four ideas to put to work
Find the method you need
Start with: Portfolio returns, benchmark weights, risk measures and basic performance reporting.
METHOD 01
Choose a fair comparison
A benchmark should represent the mandate before performance is known.
- Match the investment universe and mandate.
- Specify the benchmark in advance.
- Check measurability, investability and accountability.
Worked example
- Given
- A domestic small-cap manager is compared with a global large-cap index.
- Calculate / decide
- Size and geographic exposures differ from the mandate.
- Result
- Reassess the benchmark before attributing the excess return to skill.
Watch for: Choosing a weak benchmark after seeing returns manufactures apparent outperformance.
Practise this ideaMETHOD 02
Separate allocation and selection
Use one stated attribution convention consistently.
- Record portfolio and benchmark sector weights and returns.
- Apply the stated formula without mixing conventions.
- Reconcile all effects to total active return.
Worked example
- Given
- Portfolio sector weight 60%; benchmark 50%; sector benchmark return 10%; total benchmark return 6%.
- Calculate / decide
- Brinson-Fachler allocation = (0.60 - 0.50) × (10% - 6%).
- Result
- A +0.40 percentage-point allocation effect for this sector.
Watch for: A single sector’s allocation effect is not the entire portfolio’s active return.
Practise this ideaMETHOD 03
Read downside evidence
A ratio depends on its return definition, horizon and risk denominator.
- Identify the required return or benchmark.
- Use the matching risk measure and period.
- Compare the result with drawdowns and sample limitations.
Worked example
- Given
- Return is 9%, target return 3%, downside deviation 5%.
- Calculate / decide
- Sortino ratio = (9% - 3%)/5%.
- Result
- 1.20, using the supplied target and downside deviation.
Watch for: Short histories and stale valuations can flatter risk-adjusted metrics.
Practise this ideaMETHOD 04
Investigate the manager
Combine process evidence with returns and firm-level reporting controls.
- Check people, process, capacity and operational controls.
- Evaluate fee incentives and net outcomes.
- Treat GIPS compliance as a reporting framework, not a return guarantee.
Worked example
- Given
- A manager reports good returns but lost the team that generated them.
- Calculate / decide
- Investigate whether the current process and personnel can sustain the strategy.
- Result
- Historical performance alone is insufficient for the hiring decision.
Watch for: GIPS verification does not guarantee a particular composite’s performance or future returns.
Practise this ideaQuestions about this topic
- How do measurement, attribution and appraisal differ?
- Measurement calculates performance. Attribution explains its sources under a selected framework. Appraisal evaluates performance, including the relevant risk and evidence of skill. A correct return calculation alone does not complete all three tasks.
- Why does benchmark choice affect attribution?
- Attribution explains portfolio results relative to a benchmark and model. A benchmark that does not fit the mandate can make the effects economically misleading even when they reconcile arithmetically.
- Does a high reported return establish GIPS compliance?
- No. Compliance concerns the applicable standards and guidance governing the organization and presentation. It is separate from the size of the reported return.
Apply the topic to a focused case
CFA Level 3 GIPS and performance attribution
GIPS is a standards framework for ethical, consistent performance presentation. Determine which provisions apply to the organization and presentation in the case; a favorable return is not a compliance test. For investment firms, compliance concerns the applicable firm-wide requirements, rather than declaring one attractive account compliant in isolation. Use the official standards and relevant guidance for the governing requirements.
- Case facts
- A portfolio returns 7% and its benchmark returns 6%. Allocation contributes -0.2%, selection +1.3% and interaction -0.1% under an exhaustive one-period model.
- Apply the method
- Active return = 7% - 6% = 1%. Effects sum to -0.2% + 1.3% - 0.1% = 1%.
- Interpretation
- The effects reconcile to active return. Positive selection outweighed the negative allocation and interaction contributions in this modeled period.
