Responsible investing: The ESG-efficient frontier Flashcards
What does the ESG-SR Frontier represent?
a) The trade-off between environmental and social considerations in portfolio optimization.
b) The maximum achievable Sharpe Ratio (SR) for varying levels of ESG scores.
c) The minimum variance portfolio for ESG investors.
d) The impact of ESG factors on stock price volatility.
The maximum achievable Sharpe Ratio (SR) for varying levels of ESG scores.
Which of the following portfolios balances risk and return for investors without ESG considerations?
a) ESG-Tangency Portfolio
b) Risk-Free Asset
c) Minimum-Variance Portfolio
d) Tangency Portfolio

Why does traditional ESG screening potentially hurt the Sharpe Ratio?
It reduces diversification by restricting the ability to short low-ESG stocks.
How do Type-U investors differ from Type-M investors?
Type-U investors focus solely on risk-return metrics, while Type-M investors trade financial returns for higher ESG scores.
What is the primary finding regarding governance (G) as an ESG metric in portfolio management?
It contains useful information, offering low valuations and high returns.
How does ESG integration affect expected returns, according to the framework?
High-ESG stocks deliver low expected returns when investor demand dominates pricing.
What do the authors find regarding the correlation between governance (G) and profitability?
Governance (G) is strongly correlated with future profitability, reflecting the financial benefits of good management.
Why does the empirical analysis find that environmental (E) metrics do not enhance the Sharpe Ratio significantly?
E metrics are associated with strong demand but do not predict future profitability effectively.
How does the valuation of high-ESG stocks change based on the dominant investor type?
When Type-U investors prevail, high-ESG stocks are undervalued and deliver high returns.
What is the implication of ESG integration for Type-M investors choosing portfolios on the ESG-SR Frontier?
Type-M investors choose portfolios with higher ESG scores, accepting lower Sharpe Ratios.

This is the portfolio that maximizes the Sharpe Ratio for investors without considering ESG constraints.
NB!
High-ESG stocks are undervalued when Type-U investors dominate, as they ignore ESG information.
When managing your portfolio, you notice that your sustainable investments are outperforming your non-sustainable ones. Through what channels can ESG performance impact stock returns?
A) By influencing future profitability (return premium) or increasing investor demand (return discount).
B) By reducing a firm’s exposure to industry regulations and improving short-term gains.
C) By forcing firms to increase dividends as a means of compensating ESG investors.
D) By making companies more dependent on government subsidies, leading to higher stock volatility.
A) By influencing future profitability (return premium) or increasing investor demand (return discount).
If high ESG performance correlates with future fundamentals, what does it imply about the investors in the market? (Refer to Responsible Investing: The ESG-Efficient Frontier.)
A) That ESG information is fully priced in, and there is no return advantage to ESG investments.
B) That some investors underestimate ESG’s impact on future firm profitability, creating an ESG return premium.
C) That ESG-focused firms are fundamentally less profitable, leading to lower long-term returns.
D) That government incentives entirely drive ESG stock valuations rather than actual firm performance.
B) That some investors underestimate ESG’s impact on future firm profitability, creating an ESG return premium.
What are the three types of investors in the framework proposed by Pedersen et al. (2021)?
A) Type-U (Unaware) -> Ignore ESG scores and focus solely on maximizing traditional risk-return metrics.
Type-A (Aware)-> Use ESG scores to inform risk and return expectations but do not have inherent ESG preferences.
Type-M (Motivated). -> Consider both ESG preferences and traditional metrics, willing to trade returns for higher ESG scores.
What is a key finding of Pedersen et al. (2021) regarding ESG screening (excluding low-ESG stocks)?
A) It lowers overall Sharpe ratios by reducing diversification opportunities.
B) It always enhances portfolio performance, regardless of market conditions.
C) It has no measurable impact on portfolio performance.
D) It only works in emerging markets, not in developed economies.
A
Which of the following ESG components is found to provide the most useful information for stock selection?
A) Governance (G).
B) Environmental (E).
C) Social (S).
D) All ESG components contribute equally.
Governance
What happens to high-ESG stocks in a market dominated by Type-M investors?
A) They are overpriced, leading to lower expected returns.
What happens when Type-U investors dominate the market?
A) High-ESG stocks remain undervalued, leading to higher expected returns.
According to Pedersen et al. (2021), ESG scores affect asset prices because:
A) They inform investors about future firm profitability and shift investor demand.
B) They force regulators to impose higher corporate taxes on low-ESG firms.
C) They reduce volatility, ensuring stable long-term returns.
D) They eliminate the need for risk-adjusted portfolio construction.
A) They inform investors about future firm profitability and shift investor demand.
What is a key assumption in the ESG-CAPM model developed in the paper?
That ESG scores convey meaningful information about firm fundamentals.
According to the paper, high-ESG firms tend to:
Have more motivated employees and better governance.
If a stock’s ESG score predicts future profits, what is the expected market reaction?
A) Its price rises, reducing future returns.
Why does G (Governance) contribute more to return predictions than E (Environmental) or S (Social)?
A) It correlates more strongly with future firm profitability.
B) It is the only factor that regulators strictly enforce.
C) Governance scores are fixed and do not change over time.
D) Firms with good governance avoid investor scrutiny.
It correlates more strongly with future firm profitability.
What is the primary criticism of ESG screening as an investment strategy?
It prevents shorting low-ESG stocks, reducing portfolio flexibility.
Which of the following best summarizes the conclusions of Pedersen et al. (2021)?
Integrating ESG can enhance Sharpe ratios, but ESG constraints may reduce financial returns.
