Answer:
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Explanation:
To calculate the standard deviation of the investment, we must first calculate the expected or mean return of the investment. The expected or mean return can be calculated as follows,
r = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability of state occurrence
- rA, rB, ... represents return A, return B and so on under each state
r = 0.2 * 0.16 + 0.4 * 0.12 + 0.2 * 0.05 + 0.2 * -0.05
r = 0.08 or 8%
The formula to calculate the standard deviation of a stock/investment is as follows,
SD = √pA * (rA - r)² + pB * (rB - r)² + ... + pN * (rN - r)²
SD = √0.2 * (0.16 - 0.08)² + 0.4 * (0.12 - 0.08)² + 0.2 * (0.05 - 0.08)² + 0.2 * (-0.05 - 0.08)²
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Answer:
IRR is greater than required return by 17.38 - 16.8 % = 0.58 %
so project will accept
Explanation:
given data
initial cost = $38,000
cash inflows year 1 = $12,300
cash inflows year 2= $24,200
cash inflows year 3 = $16,100
rate of return = 16.8 %
solution
we consider here IRR is = x so
present value of inflows is equal to present value of outflows .............1
we can say that it as
initial cost = present value
3800 = 
solve it we get
x = 17.38%
here IRR is greater than required return by 17.38 - 16.8 % = 0.58 %
so project will accept
Answer:
$1,250
Explanation:
Given the following :
Amount of marginable stock customer wishes to buy = $7,500
Restricted margin account with $2500 of SMA
Since the account is a restricted margin account, that is (account has fallen below intial requirement). There must be a deposit of 50% in the regulation T account.
Hence, to purchase a marginable stock of $7,500;
50% of $7,500 should be deposited;
50/100 × 7,500 = $3750
Since there is $2500 of SMA in restricted margin account
Hence, the amount needed will be ;
($3,750 - $2,500) = $1,250
