Answer:
A.) ALPHA
Portfolio A = 8.5%
Portflio B = 13.5%
B.) Sharpe measure
Portfolio A = 0.1519
Portflio B = 0.1479
Explanation:
T- bill rate (Rf) =5%
S&P 500 index ( Rm) = 10%
Portfolio A;
Expected rate of return = 9.1%
Beta (B) = 0.7
Standard deviation (s) = 27%
Portfolio B;
Expected rate of return = 12.1%
Beta (B) = 1.7
Standard deviation = 48%
Required rate of return for both portfolios;
Rf + B × (Rm - Rf)
Portfolio A :
5% + 0.7 ×(10% - 5%) = 5% + 0.7 × (5%)
5% + 3.5% = 8.5%
Portfolio B :
5% + 1.7 ×(10% - 5%) = 5% + 1.7 × (5%)
5% + 8.5% = 13.5%
A) Alpha(A) of Portfolio A and B ;
A = Expected return - Required return
Alpha of portfolio A :
9.1% - 8.5% = 0.6%
Alpha of Portfolio B:
12.1% - 13.5% = - 1.4%
B.) Sharpe measure for portfolio A and B;
Sharpe ratio = (Expected rate of return - Rf) / s
Portfolio A = (9.1% - 5%)/27% = 0.1519
Portfolio B = (12.1% - 5%)/48% = 0.1479
I will choose Portfolio A
Answer:
219 sheets
Explanation:
D = 5000 per year,
d = daily demand = 5000/365 = 13.70 sheets
T = time between orders (review) = 14 days
L = Lead time = 10 days
σd= Standard deviation of daily demand = 5 per day
I = Current Inventory = 150 sheets Service Level
P = 95% (Probability of not stocking out) q=d(L+D)z σ T+L-1
σ T+L-1= square root (T+L)=5 square root 14+10= 24.495
From Standard normal distribution, z = 1.64 for 95% Service Level (or 5% Stock out)
q=13.70*(14+10)+1.64(24.495)-150
= 218.97 →219 sheets
Answer: c. The new system contained assumptions that did not consider critical factors such as changes in time zones, travel time across hemispheres, and pilot flying hours
Explanation:
Upon review of the effectiveness of a strategic business decision using evidence-based analytics, business leaders may reverse course.
The factor that led to the reversal of the new scheduling system is that the new system contained assumptions that did not consider critical factors such as changes in time zones, travel time across hemispheres, and pilot flying hours.
