A 62-year-old retiree with $2.4 million says "put me in something safe." Her pension covers 90% of expenses and she plans to leave the portfolio to grandchildren in 30 years. "Safe" is wrong, she can afford aggressive growth.
The IPS is the governing document. It is not a suggestion. It has two components: objectives and constraints.
Return objectives must be specific and measurable. "Good returns" is not an objective. "A 7% real return to sustain $120,000 annual withdrawals over 30 years" is. If the required rate of return (the hurdle rate) exceeds what markets can deliver, you recalibrate the goals, you do not reach for return. The required return is the target the plan demands, not a forecast of what the portfolio will earn.
HIGH-FREQUENCY: The nominal return formula appears repeatedly. The additive shortcut (real + inflation) is always a trap. Use: (1 + real) x (1 + inflation) - 1. A 7% real return with 2.5% inflation = 9.675%, not 9.5%.
Common mistakes
- Treating tolerance and capacity as the same thing. Tolerance is psychological willingness. Capacity is financial ability. A near-retiree with limited assets who claims high tolerance must be allocated conservatively based on low capacity. Trap: the aggressive allocation matching stated tolerance while ignoring limited capacity.
- Using the additive shortcut for nominal return. 7% real + 2.5% inflation = 9.5% (trap). Correct: (1.07)(1.025) - 1 = 9.675%.
- Confusing Sharpe and Treynor. Sharpe uses standard deviation (evaluate the whole portfolio). Treynor uses beta (evaluate one fund in a diversified portfolio). If the question says "overall portfolio," pick Sharpe. If "a fund within a diversified portfolio," pick Treynor.
Bottom line
- The IPS governs every portfolio decision: return objectives + risk objectives + five constraints (liquidity, time horizon, tax, legal, unique)
- When risk tolerance and capacity conflict, the more conservative one governs, always
- Nominal return = (1 + real)(1 + inflation) - 1. The additive shortcut is always a trap answer
- Asset allocation explains over 90% of return variation; strategic sets long-term targets, tactical deviates temporarily
Exam shortcut
When a scenario presents a tolerance-vs.-capacity conflict, stop and identify which is lower. The answer defaults to the lower measure. Educate the client. Document in the IPS. Eliminate any answer recommending the aggressive allocation. Remember: "S for Solo, T for Team." Sharpe = Standalone portfolio. Treynor = one fund in a Team. The nominal return formula trap shows up on almost every exam, always use the multiplicative version.
