Q

How is the PV formula of an annual paying bond different than the PV formula of a semiannual paying bond?

A

semi-annual bond would require you to divide the PMT and the discount rate by 2 since its semi-annually

semi-annual bond would require you to multiple N by 2

Q

What is current yield and formula?

A

yield to maturity that neglects time value of money and principal gain or loss.

sum of coupon payments in year/ market price of bond

28
Q

What is simple yield and formula?

A

adjusted current yield calculation to include the amortized gain or loss

(sum of coupon payments in year + amortized gain or loss) / market price

29
Q

What is street convention yield?

A

assumes cash flows are made on the scheduled dates, even if on holidays or weekends

30
Q

What is true yield?

A

focus on the actual timing of cash flows, excludes weekends and holidays.

31
Q

Why is street convention yields greater than true yield?

A

true yield may delay payments if it falls on weekend producing a smaller yield

32
Q

What is a government equivalent yield?

A

yield to maturity that does actual/actual instead of 30/360

33
Q

What is yield to call?

A

measures internal rate of return assuming bond is called early by issuer at stated call price

34
Q

What is yield to worst?

A

most conservative (lowest) rate of return for a callable bond

35
Q

What is option adjusted yield?

A

an expected yield of the bond, accounting for the embedded call

represents yield consistent with the current bond price (takes into account the value of the option)

36
Q

What is the benchmark rate?

A

benchmark rate is often the yield on a comparable government bond

37
Q

What 2 things are benchmark rates composed of?

A
  1. expected real risk-free rate
  2. plus the expected inflation rate
38
Q

What 2 things are yield-to-maturity rates composed of?

A
  1. benchmark rate
  2. bond specific spread (risk premiums)
39
Q

What is the benchmark spread and formula?

A

difference between corporate bond yield and a specific benchmark yield

benchmark spread = corporate bond yield - benchmark yield

40
Q

What is the G spread and formula?

A

difference between bonds yield to maturity and government bond yield

g spread = corporate bond yield - government bond yield

41
Q

What is the I spread and formula?

A

difference between a corporate bonds yield and a similar market reference rate for the same tenor

I spread = corporate bond yield - swap rate (or MRR)

42
Q

What is Z spread?

A

Z-spread is the constant spread added to each spot rate in the benchmark curve to make the present value of future cash flows match the bond’s current price.

43
Q

What is the Z-spread formula?

A

PV = (PMT / (1+spot rate + z)^1) + (PMT / (1+spot rate + z)^2) + ((PMT + FV)/(1+spot rate + Z)^n)

spot rate = rate right now
PMT = coupon payment
z = spot rate

44
Q

What is the option-adjusted spread formula?

A

OAS = Z spread - options value (in basis points)

45
Q

What is the difference between the quoted margin and the discount margin?

A

quoted margin: the spread that the floating-rate issuer pays over the reference rate to compensate investors for accepting the issuer’s credit risk

discount (required) margin: the markets assessment of issuers current credit risk

the spread (a security’s yield relative to the yield of its benchmark) that equates the security’s future cash flow to its current market price

46
Q

What is the present value formula of a floating rate note?

A

((index + qm)*fv)/m) / (1+ (index+dm/m))^n

index = reference rate state as annual percentage
QM= quoted margin stated as annual percentage rate
FV= Par value of bond
m= number of payment periods per year
DM= required margin stated as annual percentage rate
n= number of event spaced periods to maturity

47
Q

What is the formula for pricing money market instruments using discount rates, specifically for commercial paper, Treasury bills, and bankers’ acceptances?

A

PV = FV (1 - Days/ 360 *DR)

DAYS = # of days between settlement and maturity
Year = # of days in year
DR = discount rate stated in an annual percentage rate

48
Q

What is the formula for pricing money market instruments using add-on rates, specifically for certificates of deposits and repos?

A

PV = FV / (1+ DAYS/360 *AOR)

DAYS = # of days between settlement and maturity
Year = # of days in year
AOR = add-on rate stated in an annual percentage rate

49
Q

What is the formula for calculating money market discount rates and add-on rates?

A

DR = (# of days in Year (365) / Days) * (FV - PV / FV)

AOR = (# of days Year (365) / Days) * (FV - PV / PV)

50
Q

What is maturity structure?

A

Yields varying by maturity is called maturity structure

51
Q

What are spot curves?

A

yield on zero-coupon government bonds

52
Q

What are the 3 types of yield curves?

A
  1. upward sloping (spot curve) means long loans have higher yields.
  2. flat yield curve
  3. inverted yield curve (shorter bonds have high yields)
53
Q

What is par rate?

A

represents the coupon rate for that makes a government security of a given duration trade at par.

54
Q

What is a par curve?

A

par curve plots yield to maturity for different maturities for bonds that are priced at par.

55
Q

What is the formula for par rate per period?

A

PMT / 100

56
Q

What is the par rate formula?

A

100= (PMT/(1+Z1)^1)
+ (PMT(1+Z2)^2)
+ PMT+100(1+ZN)N

z= spot rate

57
Q

How do notations on forward rates work?

A

-first number refers to length of forward period in years from today

-second number refers to the tenor of the underlying bond

58
Q

What is a forward curve?

A

plots forward rates each having the same maturity. the forward rates is an estimation of what investors expect the short-term interest rates to be

59
Q

What’s the formula for calculating the implied forward rate?

A

IFR (a,b) = [((1-Spot Rate B)^ Year for B) / ((1-Spot Rate A)^ Year for A)] ^ (1/(Year B - Year A) -1

60
Q

What’s the formula for calculating the spot rate from forward rates?

A

{[(1 + IFR 0,1) * (1 +IFR 1,1)] (^1/N)} -1= ((1+ two year spot rate (aka z)) ^2)

61
Q

When would a corporate bonds yield be less than the yield of a government bond or negative compared to a yield of a government bond?

A

if corporate bond contains an embedded option

62
Q

What is required margin (aka discount margin)?

A

yield spread over or under a reference rate, reflecting the credit risk of an issuer. change in the required margin come from change in issuers credit risk

63
Q

What’s the difference between forward rate and spot rate?

A

spot rate represents the current exchange rate, while the forward rate is a predetermined rate for future transactions

64
Q

What is the formula for linear interpolation?

A

lower year spot rate yield + ((year you looking for spot rate - lower year) / (high year- lower year) * (higher year spot rate yield - lower year spot rate yield)

Eg. The current 5-year and 10-year Treasury spot yields are 2.10% and 2.85%, respectively.
Use linear interpolation to calculate the yield on a 7-year security.

2.10% + ((7-5)/(10-5)) * (2.85 -2.10)

65
Q

What is the one exception to the maturity effect?

A

the only exception is for low coupon, long-term bonds trading at a discount
