A 10-year maturity, 10% coupon bond has a par value of $1,000 and semi-annual coupon payments. You purchase the bond at face value when it is issued. You hold the bond for 6 months, collect the first coupon payment, and then sell the bond immediately. If the bond's yield-to-maturity is 4.6% when you sell it, what is your percentage return over this 6-month holding period?
