所以如果要plot mean against variance,应该是双曲线: 实线:rho=0,点虚线:rho=-1,虚线:rho=1 另外,关于上述组合收益方差的表达式,如果 ρ=±1 ,则可以配成完全平方数,从而实现perfect hedge;如果 −1<ρ<1 ,组合方差则严格大于0 Also, dσp2dw1=2w1(σ12−2ρσ1σ2+σ22)⏟≥0−2(σ22...
• Re-test all of your strategies for the 2023-2024 time period and plot the daily value of your portfolio over these two years using the daily adjusted closing prices provided in the new dataset (adjclose_2023_2024.csv file). Use the new initial portfolio consisting of “HOG” = 10,9...
We plot Fig. 8.3 to show which strategy performs best under the risk measure CVaR. When comparing Figs. 7.3 and 8.3, we observe that the results are similar for both VaR and CVaR risk measures in the long-term investment but very different in the short-term investment. For VaR, the SPM...

minimum variance curve in the mean-variance plot is a parabolic curve. 19 Minimum variance set and efficient funds The left boundary of a feasible region is called the minimum variance set. The most left point on the minimum variance set is called the minimum variance point. The portfolios ...
Analysis of decomposition isopleths for combinations of mean and variance reveals that more reactive organic matter mixtures plot higher than less reactive ones within a [k, s2k ] co-ordinate system, and the decomposition rate is constrained by a line drawn from the origin to a tangential ...

Comparing this plot with the single period one, we see some notable differences. The returns of all the portfolios are considerably smaller, and Asset 2 has a lower geometric mean than Asset 1, whereas it had a higher arithmetic mean. Nevertheless, as we increase the allocation of Asset 2 ...
