          LOS 8.l: Explain measures of sample                                  8. Statistical Concepts and Market Returns (B)
          skewness and kurtosis, p.154


           Kurtosis -degree to which a distribution is more or less “peaked” than a normal distribution.



                                                                                     A leptokurtic return distribution has more
                                                                                     clustering around mean and larger
                                                                                     fluctuations represented by fatter tails; so,

                                                                                     more risk –why?

                                                                                     Greater probability of an observed value
                                                                                     being either close to, or far from the mean

                                                                                     (close to the tails).

                                                                                      Mesokurtic – same as normal distribution.

                                                                                      A platykurtic return distribution is less

                                                                                      clustering around mean and less fatter tails;
                                                                                      so, less/lower risk –why?


                                                                                    Greater probability of an observed value being
                                                                                    very close to the mean! Away from the fails!
