Baron buys a bond whose Par=$1,000, Coupon=6%, semiannually paid, Maturity=8 years, and Price= $1,000. He invests the coupons at a uniform rate of 3% per six months until he sells the bond at t=2years, shortly after receiving the fourth semiannual coupon. If Barons realized return turns out to be 7% per year, what was the bonds YTM at the time of its sale at t=2 years?
