Chap 3 Flashcards
(50 cards)
How many years do notes mature in?
10 years or less
How long do treasury bills take to mature?
A year or less
Treasury bonds, notes, and bills are traded in the
fixed income market
What bond price do you use when calculating the yield? Clean or dirty?
Clean price also known as flat price
How do you present value a bond?
Present value of all coupons (FV x r x 6/12) plus the present value of (redemption value + final coupon)
The interest rate on 10-year U.S. Treasury bonds was highest in…
1977-1984
What is special about bonds with long maturity dates?
Bonds with long maturities end up with short maturities when they approach the final payment date.
Thus you will encounter 30-year bonds trading 20 years later at the same prices as new 10-year notes (assuming equal coupons).
Are long term or short term bonds more sensitive to a change in interest rate?
The price of long-term bonds is more sensitive
How does interest affect price?
They are inversely related. The higher interest rate results in a lower price.
How do you know if a bond is selling at a premium or discount?
Premium: cpn rate > yield
Discount: yield > cpn rate
Bond investors hope for interest rates…
to fall so the value of their investment increases
What is the equation for rate of return?
(coupon income + price change)

Does a change in interest affect near or distant cash flows more?
the value of distant cash flows
What does duration (Maculay duration) measure?
weighted average of the times to each of the cash payments
the lower the coupon, the higher the average time to each cash flow
-because a higher proportion of the cash flows occurs at maturity, when the face value is paid of
duration also predicts the exposure of each bond’s price to fluctuations in interest rates
-ex: if interest rates drop 1%, will there be a greater price increase in a 3% cpn bond or a 9% if they have the same maturity time? (3%)
When interest rates change, will the price of a higher or lower cpn bond be more affected?
Lower cpn bond
How is duration calculated?
- chart with (years to maturity) on the left most column
- cpn payment
- then the pv of cpn payment
- then the fraction of the pv of cpn over total pv
- then the year T times this fraction
Why do investors track duration?
because it measures how bond prices change when interest rates change
What is modified duration?
volatility = duration/ (1+ yield)
Say the duration is 5.47%, what does this mean?
This means that a 1% change in the yield to maturity should change the bond price by 5.47%.
What is the term structure of interest rates?
The relationship between short- and long-term interest rates
What does a downward sloping term structure mean?
long-term interest rates were lower than short-term rates
Is modified duration a good predictor for large changes in interest rates?
No, modified duration is a good predictor of the effect of interest rate changes only for small moves in interest rates
What if you calculate macaulay duration assuming annual cpn’s and then you want it for semi annual?
To calculate modified duration with semiannual coupons you need to divide Macaulay duration by the semiannual yield to maturity.
What is a spot rate? When do we use r1 vs r2 etc.?
r1 is a one year spot rate. We would use this when we need the pv of a single cash flow 1 year from now
r2 is the two year spot rate we would use if we needed to discount back 1$ that is paid at the end of 2 years
if you had an investment that paid $1 at the end of year 1 and again at the end of year 2, you would use r1 for the first and r2 on the second
