Q

Key results given assumptions

A
  1. If bond is held to maturity, annualized rate of return = YTM of the bond when purchased, if the YTM of the bond (and hence the reinvestment rate) does not change over the life of the bond.
  2. If a bond is sold before maturity, rate of return = YTM at purchase if the YTM has not changed since purchase.
  3. If the YTM increases (decreases) after the bond is purchased but before the f irst coupon date, if bond is held to maturity, realized return that is higher (lower) than the original YTM of the bond when purchased.
  4. If the YTM increases (decreases) after the bond is purchased but before the first coupon date, if bond is held for a short (long) period, realized return that is lower than the original YTM of the bond when purchased.

Q

Horizon Yield

A

A bond investor’s horizon yield is the compound annual return earned from the bond over the investment horizon.
It is calculated by comparing the purchase price of the bond to the end value derived from holding the bond, which includes coupons, interest earned on reinvested coupons, and the sale price (or principal payment amount, if the bond is held to maturity).

Q

Carrying Value

A

At dates between the purchase and the maturity, the value of a bond at the same YTM as when it was purchased is its carrying value, and it re flects the amortization of the discount or premium since the bond was purchased.

A

Change in Full price of Bond when YTM changes by 1 Basis point

Step 1 Calculate YTM
Step 2 Calculate Prices for +1 BP (V1) and -1 BP (V2)
Step 3 = (V2 - V1)/2 = PVBP (or V0-V1)

Full Value = PVBP * Bond Position/Par Value

30
Q

Bonds with longer maturity will have (higher/lower) interest rate

A

higher (in usual instances)

31
Q

Bonds with higher coupons will (increase/decrease) interest rate risk

A

decrease - less sensitive to changes in yield as duration will be shorter

32
Q

FRNS - interests increase –> coupon increase ie price risk is

A

low

33
Q

A

decrease

34
Q

Macaulay Duration for Perpetuity

A

=(1 + YTM)/YTM

35
Q

Exception for MacDauration

A

Deep Discount Bonds
As maturity increases, Duration increases, but at very high maturity, duration starts declining

36
Q

Effective Duration

A

For Callable/Putable Bonds

Analyzing interest rate risk for bonds with embedded options is based on shifts in the benchmark curve (e.g., government par rates), rather than changes in the bond’s own yield. This measure of price sensitivity is referred to as effective duration ie % change in price per 1% change in benchmark yield

= (V2 - V1)/2xV0xchange in benchmark

37
Q

EffDur and Credit Spread

A

Effective duration separates the effects of changes in benchmark yields from changes in the spread for credit and liquidity risk. Modi ied duration makes no distinction between changes in the benchmark yield and changes in the spread.

Effective duration re flects only the sensitivity of the bond’s value to changes in the benchmark yield curve and assumes all else (including spreads) remains the same.

38
Q

Effective Convexity

A

EffDur does not take into account that the yield curve’s convexity - Eff Con incorporates this

Value derived from EffCon is much closer to the actual Value rather than the Value derived from EffDur not taking into account EffCon

39
Q

Convexity of Bonds

A

While the convexity of any option-free bond is positive, a callable bond can exhibit negative convexity. This is because at low yields, the call option becomes more valuable, and the call price puts an effective limit on increases in bond value,

40
Q

Value using ED

A

Change in BP = ED x Change in YTM

This gives percentage

If change in y=+, change in BP=–, vv

41
Q

Value using ED & EC

A

Change in BP = EDChange in YTM + 1/2EC*(Change in YTM in %)^2

In this only ED*Change in YTM is positive or negative according to the inverse relationship between YTM and Price

EC Part remains positive for both price is always understated whether YTM increases or decreases

42
Q

Negative Convexity

A

While the convexity of any option-free bond is positive, a callable bond can exhibit negative convexity. This is because at low yields, the call option becomes more valuable, and the call price puts an effective limit on increases in bond value,

43
Q

Putable Bond Yield Curve

A
  • Positive Convexity
  • At higher yields, the put becomes more valuable, so that the value of the putable bond decreases less than that of an option-free bond as yield increases. This means the duration of a putable bond is less than that of an equivalent option-free bond at high yields.
44
Q

Key Rate Duration

A

Accounts for nonparallel shifts in benchmark yield.
AKA partial duration, is defined as the sensitivity of the value of a bond or portfolio to changes in the benchmark yield for a specific maturity, holding other yields constant.

The sum of a bond’s key rate durations equals its effective duration.

KRD = ModDur x weight in portfolio

45
Q

Shaping Risk

A

Key rate duration is particularly useful for measuring shaping risk, de fined as the effect of a nonparallel shift in the yield curve on a bond portfolio. We can use the key rate duration for each maturity to compute the effect on the portfolio of a yield change at that maturity. The effect on the overall portfolio is the sum of these individual effects.

46
Q

Analytical v Empirical Durations

A

Analytical = ModDur, MacDur, EffDur, KRD

Empirical = actual observed historical relationship between benchmark yield changes and bond price changes. Used when assumption of constant credit spread is not justified.

47
Q

Revise Portfolio Durations

A
  1. MacDur
  2. EffDur = Sum of wi*xi/Sum of wi
    wi = Marekt Value (MPxFV)
    xi = Di = Individual durations
48
Q

Effective duration is more appropriate than modified duration for estimating interest rate risk for bonds with embedded options because these bonds:

A

have uncertain cash flows that depend on the path of interest rate changes.

49
Q

When an embedded option has significant value, relative to an equivalent option- free bond, the effective duration of a bond with an embedded option will most likely be:

A

lower

50
Q

A

With an American style embedded call option, a bond may be
called any time after its first call date.

56
Q

Q

An investor holds $100,000 (par value) worth of TIPS currently trading at par. The coupon
rate of 4% is paid semiannually, and the annual inflation rate is 2.5%. What coupon payment
will the investor receive at the end of the first six months?

A

$100,000 x 1.0125 = $101,125 ie new capital

Coupon is 4%/2 on New Capital
ie $2,025.

private placement

65
Q

Which type of issuer is most likely to issue bonds by auction?

A

sovereign.

Corporate bonds are
typically issued in an underwriting or private placement process while municipal bonds are

Q

A bond is quoted at 96.25 bid and 96.75 ask. Based only on this information, this bond is
(liquid/illiquid)?

A

Illiquid

The spread between the bid and ask prices is one-half percent of par, which most likely
reflects an illiquid market for this bond. Bonds with liquid secondary markets typically
have bid-ask spreads of approximately 10 to 12 basis points.
