Q

How do you calculate the Holding Period Return? (WEEK 4: TIME VALUE OF MONEY)

A

r = (D1 +P1 - P0)/ P0

Where:
P0: Denotes value of investment at beginning of holding period
P1: Denotes value of investment at end of holding period
D1: Denotes dividend or interest payment received during that period

Q

How do you calculate the nominal rate of return? (WEEK 4: TIME VALUE OF MONEY)

A

Real rate of return x Inflation

e.g Real rate of Return = 8%
Inflation 4% (add it on to the existing 100%)

Looking at T0: £1000

  1. 08 X 1.04 = 1.1232
  2. 1232 X 100 = 1123.20 Nominal Cash flow T1
  3. 20 is financially equal to 1000 in the last period

Can see the nominal rate of return is 12.32%

Q

How do you calculate Perpetual Bonds? (WEEK 5: BONDS)

A

PV = C/R
Where:
- PV: Present Value of bond
- C: The coupon rate x Nominal (par) value of the bond

Works the same for regular PV where C is just the Cashflow

Q

How you calculate conventional bonds? (Bonds that have fixed payback period) (WEEK 5: BONDS)

A

PV =
PV(P) = C(1/R-1/(1+R)t) + V/(1+R)t

Where V is the par value

Where t is to the power of

Q

How do you calculate the (Nominal) interest yield? (WEEK 5: BONDS)

A

Coupon/ Market Price

17
Q

How do you calculate the Redemption Yield (or YTM) if the time period is 1?(WEEK 5: BONDS)

A

R = C+V/P - 1

If any other time period then you have to extrapolate (idfk)

18
Q

How do you calculate spot rates?(WEEK 5: BONDS)

A

Finding R1:
P= C+V/ 1 +R1
Simply just rearrange

Finding R2:
P= C/1+R1 + C+V/ (1+R2)2
Simply just rearrange

Finding R3:
P = C/1+R1 + C/(1+R2)2 + C+V/ (1+R3)3
Simply rearrange

ETC.

19
Q

How do you calculate Zero Coupon Bonds? (WEEK 5: BONDS)

A

P0 = 100/ (1 + Rt) t
- Where Rt = tth period spot rate

But can also use:
P0 = 100/ (1+ R) t
- Where r = Yield to maturity

Therefore, Spot Rate equals yield to maturity for zero coupon bonds

20
Q

How do we calculate Forward Rates? (WEEK 5: BONDS) SEE NOTES FOR BETTER EXPLANATIONS

A

Focusing on £100 in 2 years:

Step 1: Find Present Value of £100 one year from now (PV):

  • Use Discount Rate f 1,2 where 1,2 indicates that this is a rate from year one to year two. We refer to it as a forward rate:

PV = £100/ (1+ F 1,2)

Step 2: Find present value of PV0 of PV1:

PV0 = PV1/ (1+R1)

F 1,2 = 100 / PV0 (1+R1)

21
Q

How do you calculate the Holding Period of Return? (WEEK 4: TIME VALUE OF MONEY)

A

r = d1+ P1 -P0/ P0

Where:
D1 - Dividend when Share ends
D0 - Dividend when you bought share
P0 - Price when bought

22
Q

How do you calculate the Dividend Growth Model? (Calculating the Price of Share)? (WEEK 6: VALUATION OF SHARES)

A
P0 = d1/r-g
D1 = d0(1+g)
Where:
p0 = Current Price 
d1 = Future Dividend
r = Required rate of return 
g = Growth rate of dividend
23
Q

What is the required rate of return based on the second dividend growth model?(WEEK 6: VALUATION OF SHARES)

A

r = d1/po +g

24
Q

How do you calculate G? (WEEK 6: VALUATION OF SHARES)

A

D1 - D0/D0
