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.

Answer 1

The maximum achievable Sharpe Ratio (SR) for varying levels of ESG scores.

Question 2

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

Answer 2

Tangency portfolio

Question 3

Why does traditional ESG screening potentially hurt the Sharpe Ratio?

Answer 3

It reduces diversification by restricting the ability to short low-ESG stocks.

Question 4

How do Type-U investors differ from Type-M investors?

Answer 4

Type-U investors focus solely on risk-return metrics, while Type-M investors trade financial returns for higher ESG scores.

Question 5

What is the primary finding regarding governance (G) as an ESG metric in portfolio management?

Answer 5

It contains useful information, offering low valuations and high returns.

Question 6

How does ESG integration affect expected returns, according to the framework?

Answer 6

High-ESG stocks deliver low expected returns when investor demand dominates pricing.

Question 7

What do the authors find regarding the correlation between governance (G) and profitability?

Answer 7

Governance (G) is strongly correlated with future profitability, reflecting the financial benefits of good management.

Question 8

Why does the empirical analysis find that environmental (E) metrics do not enhance the Sharpe Ratio significantly?

Answer 8

E metrics are associated with strong demand but do not predict future profitability effectively.

Question 9

How does the valuation of high-ESG stocks change based on the dominant investor type?

Answer 9

When Type-U investors prevail, high-ESG stocks are undervalued and deliver high returns.

Question 10

What is the implication of ESG integration for Type-M investors choosing portfolios on the ESG-SR Frontier?

Answer 10

Type-M investors choose portfolios with higher ESG scores, accepting lower Sharpe Ratios.

Question 11

ESG-SR Frontier

Answer 11

The curve shows the maximum achievable risk-adjusted returns for varying levels of ESG scores

Question 12

Tangency Portfoliio

Answer 12

This is the portfolio that maximizes the Sharpe Ratio for investors without considering ESG constraints.

Question 13

NB!

Answer 13

High-ESG stocks are undervalued when Type-U investors dominate, as they ignore ESG information.

Question 14

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.

Answer 14

A) By influencing future profitability (return premium) or increasing investor demand (return discount).

Question 15

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.

Answer 15

B) That some investors underestimate ESG’s impact on future firm profitability, creating an ESG return premium.

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.

Answer 19

A) They are overpriced, leading to lower expected returns.

Answer 21

A) They inform investors about future firm profitability and shift investor demand.

Question 22

Answer 23

Question 24

If a stock’s ESG score predicts future profits, what is the expected market reaction?
