CAPM For a risky return r, CAPM equation is Er -r- B(E[rm] -r), where r is risk-free rate, Tm is market return, and is loading of risky return r on market return rm In what follows, X and Y denote arbitrary assets, B risk-free bond, M market portfolio. Determine which of the following scenarios are consistent or inconsistent with mean-variance efficiency (that is, CAPM). In your answer, write "Consistent" or "Inconsistent", and give brief explanation. 25% 12% 0.8 1.2 25...
