    Par yield from Spot Rates.

    Hi @RaamZen, The par yield is the coupon rate that causes the Bond price = par value. Usually, the bond is assumed to provide semi-annual coupons. If the coupon rate is c per annum, then c/2 is the coupon rate every six months. Using the zero spot rates above, the value of the bond is equal to...

    The Credit Crisis of 2007

    What a small world we live in, Brian. One thing I can say about Blythe Masters was that she was very approachable and helpful. I remember asking her if she would send me her booklet on Credit Derivatives which she promptly did. Thanks for the info on ABS CDO's.....interesting and informative:)...

    The Credit Crisis of 2007

    In addition to ratings being bought, audits are also bought! Talking about doing internal credit ratings, doesn't Basel II recommend internal ratings and this is superseded by Basel III which reverts to external ratings. Correct me if I am wrong on that... Did you know that Blythe Masters at JP...

    The Credit Crisis of 2007

    Hi Brian, That is very interesting information. It is the game of just passing the buck and the buck never stops! When I was working at Bankers Trust (now part of Deutsche bank), they had sold inverse floaters to P&G and Orange County. It was not as though the clients were not aware of the...

    What is true yield?

    Hi @DTu, The prices of money market instruments are sometimes quoted using a discount rate. An example is the T-bills in the US. If the price of a 91-day T-bill is quoted as 8, this means that the rate of interest earned is 8% of the face value per 360 days. Suppose that the face value = $100...

    Non-dividend-paying investment asset in cost of carry model

    Hi @DTu, I am just hazarding a guess here: (1) In the absence of storage costs and income, the forward price of a commodity that is an investment asset (gold and silver) is given by: F(0) = S(0)*e^rT This is the same as for a non-dividend paying stock where the cost of carry is also r...

    P1.T3.505. Bond interest payments and zero-coupon bonds

    Hi @Yuchao and @Deepak Chitnis, You are right in that David has forgotten to give the coupon years. However, I did go to his Answer in the student forum and found that the coupons of $4.5 were paid on April 1st 2015 and October 1st 2015. Using the Bond worksheet in the TI BA II Plus Financial...

    R26.P1.T4.Allen_v5.1 pag 40 Question 1

    Got it....the question is on Page 37 of Allen's Study Notes. I get the same answer as David and Deepak. Just wanted to add that the 9 years is Modified Duration, which is a measure of the yield based interest rate sensitivity of the bond. In the case of a Zero coupon bond under continuous...

    Does adjusted R^2 have any physical interpretation?

    Hi @Deepak Chitnis and @S666, There are two interpretations that follow from your formula for Adjusted R-Square below: Adjusted R-Square is computed using the formula 1-((1-R^2)*(N-1)/(N-k-1)). (1) When the number of observations (N) is small and the number of predictors (k) is large, there...
