4 Yield measures Suppose there is a 3 year bond, with a 6% coupon rate, semiannual coupons, and a face value of $1,000: If you pay $947.58 for this bond, what is your annual return on the bond investment ?

5 Yield measures Current yield Current yield is calculated by dividing the annual coupon payments by the bond’s price: Current yield = Coupon payments Bond price Coupon payments = $60 per year (= 6% × $1,000) Price of $947.58 Current yield = $60 = 6.33% $947.58

6 Yield measures Current yield is an incomplete measure of the return on bonds since it only considers the coupons but ignores : 1) Any capital gain (or capital loss ) on this bond: for example, at the maturity date the face value is repaid and there will be a capital gain at that time ($1,000 - $947.58 = $52.42) and 2) Any income from reinvestment of previous coupons Recall from ADMS3530 : current yield on bonds is similar to dividend yield on stocks in that both are incomplete measures of the rate of return on bond (or stock) investment

7 Yield measures Yield to maturity is defined as the interest rate which makes the present value of the bond’s cash flows equal to its current price. Yield to maturity ( YTM , or yield ) is also the internal rate of return ( IRR ) on bond investment ( Why ? )

8 Yield measures Yield to maturity For the 3 year bond you are working with, you know the price of the bond is $947.58 To calculate the yield to maturity, you must solve for “ r ” (the interest rate) in the following equation: 6 6 ) r 1 ( 000 , 1 $ ] ) r 1 ( r 1 r 1 [ 30 $ 58 . 947 $ + + + - × = There is no closed-form solution, so you have to use a financial calculator ( see the next slide ... )

9 Yield measures Yield to maturity If you use a TI BAII Plus financial calculator, then apply the following keystrokes: 30 (PMT); 1,000(FV); 6(N); -947.58(PV); CPT (I/ Y) You will see 4%. This is the interest rate per 6 months. The yield to maturity is an APR with semiannual compounding . So the yield to maturity is 4% × 2 = 8%

10 Yield measures Example 1 : bond price = $1,000 = par, coupon rate = 6%, current yield = $60 / $1,000 = 6%, and YTM = 6% Example 2 : bond price = $947.58 < par, coupon rate = 6% < current yield = $60 / $947.58 = 6.33% < YTM =
