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. Entor percentages "as is", 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 1-year Zero and the 4-year Zero, 1-year Zero HPRC 1% 4-year Zero HPR b) Recalculate the return on the 4-year zero if you believe in the expectations hypothesis. 4-year Zero HPR
