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 answers to 2 decimal places. Enter percentages "as-ls", without the % sign.) a) If you believe that the yield curve next year Zero and the 4-year Zero. be the same as today's, calculate the holding period return (1-year) on the 1-year 1-year Zero HPR % 4-year Zero HPR b) Recalculate the return on the 4-year zero if you believe in the expectations hypothesis. 4-year Zero HPR
