Calculate PV01 of a 10% bond

You can calculate the PV01 by calculating the value of a bond and the value of the same bond with a one basis point change in yield. In this exercise, you will calculate the PV01 of a bond with a $100 par value, 10% coupon, and 20 years to maturity assuming 10% yield to maturity.

Use the bondprc() function you created in Chapter One to value the two bonds. This function has been preloaded in your workspace. Make sure the result is a positive number.

Exercise instructions

Calculate PV01 using the formula you saw in the video. Remember that PV01 is equivalent to the value of one bond minus the value of the other bond. To calculate this, you should use two calls to bondprc().
To get the correct answer, you should subtract the bond with the YTM of 10.00% from the bond with the YTM of 10.01%.
Also remember to take the abs() of this formula to ensure your output is positive.

The fixed income market is large and filled with complex instruments. In this course, we focus on plain vanilla bonds to build solid fundamentals you will need to tackle more complex fixed income instruments. In this chapter, we demonstrate the mechanics of valuing bonds by focusing on an annual coupon, fixed rate, fixed maturity, and option-free bond.

Estimating Yield To Maturity - The YTM measures the expected return to bond investors if they hold the bond until maturity. This number summarizes the compensation investors demand for the risk they are bearing by investing in a particular bond. We will discuss how one can estimate YTM of a bond.

Interest rate risk is the biggest risk that bond investors face. When interest rates rise, bond prices fall. Because of this, much attention is paid to how sensitive a particular bond's price is to changes in interest rates. In this chapter, we start the discussion with a simple measure of bond price volatility - the Price Value of a Basis Point. Then, we discuss duration and convexity, which are two common measures that are used to manage interest rate risk.

We will put all of the techniques that the student has learned from Chapters One through Three into one comprehensive example. The student will be asked to value a bond by using the yield on a comparable bond and estimate the bond's duration and convexity.
