Which of the following is most CORRECT? O A fixed-rate bond will sell at a premium when its coupon interest rate is equal to the going rate of interest, ka. O The price of an existing bond moves in the same direction as interest rates (i.e. if interest rates rise, bond prices also rise). O Zero coupon bonds pay no annual interest and are issued at a premium to their par value. If current interest rates are above the fixed coupon rate of a bond that bond will sell at a discount If a corporation's bonds are selling at a discount, then the YTC is probably the expected return for the investor
