Actual exam question for CFA Institute's Sustainable-Investing exam

Question #: 7
Topic #: 4

[All Sustainable-Investing Questions]

When using mean-variance optimization (MVO) models, ESG-related issues most likely:

AHave the potential to add new sub-asset classes

BWould be inappropriate for expanding regional asset mixes

CHave no impact on model assumptions about expected return and volatility

Show Suggested Answer

Suggested Answer: A

ESG factors can create new sub-asset classes(e.g.,green bonds, impact investing funds) that affectrisk-return trade-offs in mean-variance optimization (MVO) models.

MVO assumes that ESG factors can impact risk-adjusted returns, meaning ESG data can influenceasset weightings and expected volatility.

Regional asset mixes (B) are still relevant for ESG investing, and ESG factorsdo impact expected returns and volatility (C).

Haha, I bet the exam writers are trying to trick us with that option C. As if ESG has no impact on the model - what a joke!

Hmm, I'm not sure about B. Expanding regional asset mixes could actually benefit from incorporating ESG considerations.

C is definitely wrong. ESG factors can significantly impact expected returns and volatility, so they should be accounted for in the model assumptions.

Not sure about this one. I'll need to weigh the pros and cons of each option and try to eliminate the ones that don't seem quite right.

I'm feeling pretty confident about this. ESG issues would likely impact the expected return and volatility assumptions in the model, so C is probably the right answer.
