Later on research was conducted and the creators of CAPM theory related diversifiable which are unsystematic risks and non-diversifiable which are systematic risks for all the securities in the portfolio. Some management individuals conceived that CAPM is not genuine as it dominates participating management and investment study. Fabozzi and Markowitz (2002) state “even though the idea is not true it does not mean that the constructs introduced by the theory are not important.
