Holding Period Return
 P0= 1000; C=100; n=5 years; If you sell in two years
when r=9% you will get P2= 1025.3 (FV=1000; N=3; r=9;
PMT=100; PV=?)
 Then your holding period return=11.11 based on the
following cash flows PV=-1000;
FV=1025.3+209.5=1234,8, n=2; r=? ( return for coupon
payments 100 paid in year 1 is reinvested @9.5 and
makes 109.5 at year two plus 100 for second year =209.5)
 I would rather not worry about reinvestment of coupon
and set it up as PV=-1000; PMT =100; n=2; FV = 1025.3
and find the return; note FV depends on interest rate
when you sell the bond before maturity!
