Hi,
I have one question about getting the yield date based on bond price.
Assume today is 11/05/2011
Continuous compounding convention, discount factor is e^{-tr(t)}
We have the bond quotes on Nov 5, 2011
Coupon Maturity Ask price
6.625 2/15/2012 100
9.125 2/15/2012 100.6875
7.875 8/15/2012 100.75
8.25 8/15/2012 101.03125
I am using the term structure formula
PV(present value of asking price) 100 = x_{0}(cash flow} + d_{1} * x_{1} (
100+6.625*0

Sorry, typo, it should be yield rate, not date

这两个式子里的x(0) 不应该相等吧?

The quoted price is clean price, but you have to use dirty price (clean
price + accrued interest) in your equation because you have to pay more than
100 to get 6.625, 2/15/2012 bond.
Simply think that you can get a 6.625/2 coupon after holding a bond for 3
months, you will get 6.625*2 >12% annualized yield rate, which is of course
ridiculous.

Thanks for the reply,
I am a novice, If I am understanding correctly, you paid the bond asking
price,
then you will get coupon + principal back at the maturity date.
11/05/2011 is between two coupon date, so I proportionally get the coupon
100/182*6.625.
What's the correct way to get the yield rate/interest rate using the data
above?

you will pay ask price + accrued interest. So for 6.625, 2012 bond quoted at
100, you have to pay 100 + ~ 90/360*6.625 = 101.6 (assuming 30/360 day
count, deal close at Nov. 15, and twice a year coupon frequency) to get the
bond.

the
So from Nov 5 to Feb 15 is 100 days, assuming bond yield rate y, we will
have
($100 + 6.625*(180-100)/360) = exp(y*100/360)*($100+6.625*0.5)
this gives y = 6.4704%
whereas the second one gives:
($100.6875 + 9.125*(180-100)/360) = exp(y*100/360)*($100+9.125*0.5)
which gives y = 6.4167%
Should we expect this to be the same, or that's close enough?

Thanks,
the original question is using model
r(t) = a_{0} + t*a_{1} + ... + t^4*a_{4} to do a regression.
We have 14 more data in the following years, like
8.25 2/15/2013 101.21875
8.75 2/15/2013 101.375
We should plot a estimated yield curve. Because yield curve is different
because of different coupon, then the yield means the 0 coupon yield curve I
should plot, correct?

no, yiled curve is the yield of coupon-yielding(2 coupons per year) US
Treasury Bonds.
spot curve is the zero-coupon curve calculated from Treasury.

Thanks for the reply,
but since we have 12 different bonds, different asking prices, I assume they
all have different yield curve, which yield curve should I plot?

Once spot rate known,
r(t) = a_{0} +... a{4}*t^4
does the yield for different coupon/same maturity date always the same ? no
matter what's the coupon value.
Higher yield will cause higher bond price, but yield stay the same???
