Common core

Expected portfolio return

E(Rp) = Σ wi × E(Ri)

Calculator check

(0.60 × 0.08 + 0.40 × 0.03) × 100 = 6 %.

Variables, assumptions & common error
Variables and units
wi: portfolio weights summing to one; E(Ri): expected asset returns for the same horizon.
When it applies
Beginning weights with no intervening rebalance; values are expectations, not promises.
Common error
A weighted-average return does not capture portfolio risk or liability suitability.

Common core

Two-asset portfolio variance

σp² = wA²σA² + wB²σB² + 2wAwBσAσBρAB

Calculator check

0.5^2 × 0.2^2 + 0.5^2 × 0.1^2 + 2 × 0.5 × 0.5 × 0.2 × 0.1 × 0 = 0.0125 squared-return units.

Variables, assumptions & common error
Variables and units
w: asset weights; σ: return standard deviations as decimals; ρ: correlation.
When it applies
A two-asset portfolio; covariance estimates refer to one consistent return period.
Common error
Take the square root to obtain volatility. Variance and standard deviation are not interchangeable.

Common core

Sharpe ratio

Sharpe = (Rp - Rf) / σp

Calculator check

(0.09 - 0.03) / 0.12 = 0.5 ratio units.

Variables, assumptions & common error
Variables and units
Rp: mean portfolio return; Rf: risk-free return; σp: total return volatility over the same frequency.
When it applies
A risk-adjusted historical or expected summary with a strictly positive volatility denominator.
Common error
Total volatility differs from tracking error. Non-normal returns can make this metric incomplete.

Common core

Information ratio

IR = Mean active return / Tracking error

Calculator check

0.02 / 0.04 = 0.5 ratio units.

Variables, assumptions & common error
Variables and units
Active return: portfolio minus benchmark; tracking error: standard deviation of those active returns.
When it applies
Use the same frequency and benchmark for numerator and denominator; tracking error is positive.
Common error
A higher IR is not proof that the benchmark represents the client mandate.

Common core

Brinson-Fachler allocation effect

Allocation_i = (wp,i - wb,i) × (Rb,i - Rb)

Calculator check

(0.40 - 0.30) × (0.10 - 0.06) × 10000 = 40 basis points.

Variables, assumptions & common error
Variables and units
wp/wb: portfolio/benchmark segment weights; Rb,i: benchmark segment return; Rb: total benchmark return.
When it applies
A single-period Brinson-Fachler decomposition with aligned segment classifications.
Common error
Other attribution conventions differ. Do not mix Brinson-Fachler and Brinson-Hood-Beebower terms.

Common core

Equity-futures beta adjustment

N = (βtarget - βcurrent) × Vportfolio / (F × multiplier × βfutures)

Calculator check

(0.80 - 1.10) × 10,000,000 / (200,000 × 1) = -15 contracts.

Variables, assumptions & common error
Variables and units
N: signed contract count; V: portfolio value; F × multiplier: contract notional; βfutures: futures beta.
When it applies
Linear beta exposure, an appropriate futures hedge and no basis-risk adjustment.
Common error
A negative answer means sell contracts. State the rounding policy and residual exposure.

Portfolio Management pathway

Active share

Active share = 0.5 × Σ |wp,i - wb,i|

Calculator check

0.5 × (|0.60 - 0.40| + |0.40 - 0.60|) × 100 = 20 %.

Variables, assumptions & common error
Variables and units
wp/wb: security weights over the union of portfolio and benchmark securities.
When it applies
Fully invested long-only weights here; include zero weights for securities held only on one side.
Common error
Active share measures holdings differences, not realized active return or tracking error.

Private Wealth pathway

Future value with annual return taxation

FV = PV × [1 + r × (1 - t)]^n

Calculator check

100 × (1 + 0.08 × 0.75)^2 = 112.36 currency units at a hypothetical 25% tax rate.

Variables, assumptions & common error
Variables and units
r: annual pre-tax return; t: tax fraction applied annually to all return; n: years.
When it applies
A hypothetical flat annual tax on the entire return; no allowances, deferral or changes in law.
Common error
This teaching model is not any jurisdiction's tax calculation. Deferred gains need a different model.

Private Wealth pathway

Nominal target from a real spending target

1 + rnominal = (1 + rreal) × (1 + inflation)

Calculator check

(1.04 × 1.025 - 1) × 100 = 6.6 %.

Variables, assumptions & common error
Variables and units
rreal: required real return; inflation: expected inflation over the same annual period.
When it applies
An exact purchasing-power identity before tax, costs and uncertainty buffers.
Common error
The client's required return and ability to bear risk can conflict; the equation does not solve that conflict.

Private Markets pathway

Total value to paid-in capital

TVPI = (Distributions + Residual NAV) / Paid-in capital

Calculator check

(40 + 90) / 100 = 1.3 times.

Variables, assumptions & common error
Variables and units
All terms: cumulative currency amounts for the same fund and measurement date.
When it applies
Consistent gross/net-of-fees basis and a positive paid-in-capital denominator.
Common error
Residual NAV is not cash received. TVPI ignores the timing of contributions and distributions.

Private Markets pathway

Distributions to paid-in capital

DPI = Cumulative distributions / Paid-in capital

Calculator check

40 / 100 = 0.4 times.

Variables, assumptions & common error
Variables and units
Distributions: cash or distributed value under the stated convention; paid-in capital: cumulative contributions.
When it applies
Use the same fund, date, currency and fee basis in numerator and denominator.
Common error
DPI leaves out residual holdings. Add RVPI to reconcile to TVPI on a consistent basis.

Private Markets pathway

Residual value to paid-in capital

RVPI = Residual NAV / Paid-in capital

Calculator check

90 / 100 = 0.9 times.

Variables, assumptions & common error
Variables and units
Residual NAV: estimated remaining net asset value; paid-in capital: cumulative contributions.
When it applies
A positive denominator and a consistent valuation/fee basis with DPI and TVPI.
Common error
A valuation uplift raises RVPI without creating a distribution. Check the underlying valuation assumptions.

  1. Question 1 of 3Common core - risk-adjusted returnWritten response

    Case facts

    A portfolio returns 8%, the risk-free rate is 2% and total volatility is 10%, all annual.

    Calculate the Sharpe ratio and distinguish it from an information ratio.

    Model answer and self-review rubric

    Sharpe = (8% - 2%) / 10% = 0.60. An information ratio instead uses benchmark-relative return and tracking error. Common error: calling total volatility tracking error.

    Teaching checklist only. No official points or automated grade.

  2. Question 2 of 3Private Wealth pathway - assumptionsWritten response

    Case facts

    A hypothetical account earns 5% before an annual flat tax of 20% on the entire return. Its opening value is 200 and the horizon is two years.

    Calculate terminal wealth under the stated assumptions.

    Model answer and self-review rubric

    After-tax return is 4%; terminal wealth is 200 × 1.04² = 216.32. This stylized model assumes annual taxation of all return and is not a local tax rule. Common error: applying one year of growth to a two-year horizon.

  3. Question 3 of 3Private Markets pathway - fund metricsWritten response

    Case facts

    A fund has paid-in capital of 50, distributions of 20 and remaining NAV of 45 on a consistent net basis.

    Calculate DPI, RVPI and TVPI, then reconcile them.

    Model answer and self-review rubric

    DPI = 0.40; RVPI = 0.90; TVPI = 1.30, all in times. DPI + RVPI = TVPI. Only the distributions have been returned; the NAV remains a valuation estimate. Common error: describing TVPI as an annualized return.
