equity market valuation, p 156, example 8
-difference, on average, is 0.70
now on p . 159, example 10 part 1
-difference is 0.40, indicating it’s undervalued. however, because the historical average difference is 0.70, the smaller difference of 0.40 --> overvalued.
my question is, then, on the exam, let’s say there was a question where we had to calculate the yield difference to see if equities are undervalued/overvalued. would we have to keep the historical average (0.70) in mind and compare it to the calculated answer to see if they’re undervalued or not?
thanks!
