You observe the following yield curve YTM 1-year Zero 6.10% 2-year Zero 6.20% 3-year Zero 6.30% 4-year Zero 6,40% (Round your final newers to 2 decimal places. Enter percentages "le", without the sign.) a) If you believe that the yield curve next year will be the same as today's, calculate the holding period return (1-year) on the year Zero and the 4-year Zero 1.year Zero HPR % 4.year Zero HPRE b) Recalculate the return on the 1 year zero if you believe in the expectations hypothesis 4-year Zero HPR
