a) In the previous section of this problem set, explain why the calculated YTM of a bond could be a bad characterization (inaccurate) of the rate of return of a bond investment. Put your response in the box below: Hint [1]: how was YTM calculated from the cash flows of the bond? Hint [3]: see lecture notes on the concept of "yield illusion". Hint [2]: what assumptions were made on this TVM-based calculation? b) If YTM is a potentially bad method of calculation of a bond's rate of return, what other method of calculation is more appropriate? And why is this method always correct (accurate)? Put your response in the box below: Hint: see lecture notes on Realized Compound Yield [RCY]. PS: RCY is also termed as Horizon Yield [HY] and Total Return [TR] in other textbooks
