One year ago you bought what at that time was a 2-year zero-coupon bond. When you bought the bond, the 1-year spot rate was 3.4% and the 2-year spot rate was 4.2%. Today, when the bond has 1 year remaining until maturity, you find that all spot rates of all maturities are 3.8%. What is your realized rate of return on the bond over the past year if you decide to sell the bond today? Round and enter your answer to the nearest 4 decimal places and enter in decimal form (note 12.345% should be entered as 0.1235).]
