Prices and Yields (required rates of return) have an inverse relationship

When yields get very high the value of the bond will be very low.

When yields approach zero, the value of the bond approaches the sum of the cash flows.

Yield Measures

Bond Equivalent Yield

7.72% = 3.86% x 2

Effective Annual Yield

(1.0386)2 - 1 = 7.88%

Current Yield

Annual Interest / Market Price

$70 / $950 = 7.37 %

– Reinvestment of coupon payments

– Change in price of the bond

Holding-Period Return: Single Period

HPR = [ I + ( P0 - P1 )] / P0

where

I = interest payment

P1 = price in one period

P0 = purchase price

CoverCoverimageimage

Holding-Period Example

CR = 8% YTM = 8% N=10 years

Semiannual Compounding P0 = $1000

In six months the rate falls to 7%

P1 = $1068.55

HPR = [40 + ( 1068.55 - 1000)] / 1000

HPR = 10.85% (semiannual)
