CHAPTER 33 VALUING BONDS

VALUING BONDS The value of a bond is the present value of the expected cash flows on the bond discounted at an interest rate that is appropriate to the riskiness of that bond. Since the cash flows on a straight bond are fixed at issue the value of a bond is inversely related to the interest rate that investors demand for that bond.

Bond valuationWikipedia

Bond valuation is the determination of the fair price of a bond.As with any security or capital investment the theoretical fair value of a bond is the present value of the stream of cash flows it is expected to generate. Hence the value of a bond is obtained by discounting the bond s expected cash flows to the present using an appropriate discount rate.
