How much confidence can an investor have in positive ratio

Question

I heard conversation of the Earnings Yield Gap ratio, that is the difference among the inverse of the PER and the TIR on 10-year-bonds. This is said that if this ratio is positive then this is more advantageous to invest in equity. How much confidence can an investor have in this affirmation?

Answer 1

This is not always true that when this ratio is positive then this is more profitable to invest in equity. This is not an investment criterion; nor is any other type ratio.
