18. Consider a Zerobond (i.e., a bond that pays no coupon payment, meaning that the coupon rate on the bond is 0%) with a par value of $1,000 that will mature exactly 12 years from today. The current YTM of this Zerobond is 5.2%. Three years ago the YTM of the same Zerobond was 4.6%. Calculate the dollar price increase/decrease (2 decimal places) within the last three years. If the bond falls in price, enter your answer on D2L as a negative value (i.e., put a minus sign before your number with no space between the minus sign and the number). If the bond increases in price, record the dollar amount of the increase.
