In tackling the question about the ESG-tilted quadratic optimisation model, I will evaluate each option on its own merits and potential misconceptions.
Option 1: "The target ESG score that must be met at all costs". This is incorrect because gamma in such models is not typically a hard target threshold for ESG scores; rather, it inf......Login to view full explanation登录即可查看完整答案

Which statement is (are) false about resampled efficient frontier?
The optimal portfolio on the efficient frontier for a given investor does not depend on_______
Question at position 15 Without imposing no-shorting constraints, you found the tangency portfolio of 3 assets A, B, and C to have weights [0.6, 0.6, -0.2], respectively. What is the most precise thing you can say about the weights of the tangency portfolio once you impose no-shorting constraints?The weights will be [0.5, 0.5, 0.0].The weight on asset C will increase.The weights will remain the same: [0.5, 0.7, -0.2].None of the statements above are necessarily true.The weights on both assets A and B will decrease.
Question at position 15 Rather than tracing out the efficient frontier, you decide to calculate the Sharpe ratio-maximizing portfolio directly. You wrote the function to calculate the sharpe ratio of a portfolio given its weights as follows: def sharpe_ratio(w, μ, Σ, rf): r = w.transpose @ μ σ = np.sqrt(w.transpose @ Σ @ w) return (r - rf) / σ You then define an objective function objective(w): def objective(w): return a * sharpe_ratio(w, μ, Σ, rf) and minimize it subject to constraints using scipy.optimize.minimize. Which value of a will allow you to find the Sharpe ratio-maximizing portfolio? rf10You cannot find the maximum Sharpe ratio using the minimize function.-1
