Minimum variance set and efficient funds The left boundary of a feasible region is called the minimum variance set. The most left point on the minimum variance set is called the minimum variance point. The portfolios in the minimum variance

ocw.mit.edu4 Variance. Now that we’ve de ned expectation for continuous random variables, the de nition of vari-ance is identical to that of discrete random variables. De nition: Let Xbe a continuous random variable with mean . The variance of Xis Var(X) = E((X ) 2): 4.1 Properties of Variance. These are exactly the same as in the discrete case. 1.

If µ b is the acceptable baseline expected rate of return, then in the Markowitz theory an opti-mal portfolio is any portfolio solving the following quadratic program: M minimize 1 2 wTΣw subject to m Tw ≥ µ b, and e w = 1 , where e always denotes the vector of ones, i.e., each of the components

Variance and Standard Deviation - Penn Math
www2.math.upenn.eduVariance The rst rst important number describing a probability distribution is the mean or expected value E(X). The next one is the variance Var(X) = ˙2(X). The square root of the variance ˙is called the Standard Deviation. If f(x i) is the probability distribution function for a random variable with range fx 1;x 2;x 3;:::gand mean = E(X) then:
