A bond paying 5% coupons semiannually and YTM of 4.5% and 12 years to maturity. If the last interest payment was made 30 days ago, assuming 364 days a year, calculate the dirty price of the bond.

If you  buy a 25-yr, 6% annual coupon bond for $883.46 (when YTM is 7%) and plan to hold it for 15 yrs.  If you forecast the YTM will be 7.50% when it is sold in 15 yrs, while the reinvestment rate is expected to be 6.6% in the first 15 years, what is your average annual rate of return (horizon yield)?
