Minimum variance frontierGraph of the lowest possible portfolio variance that is attainable for a given portfolio expected return.Minimum variance frontier Similar MatchesVarianceVarianceA measure of how much an economic or statistical variable varies across values or observations. Its calculation is the same as that of the covariance, being the covariance of the variable with itself. VarianceVarianceThe difference between budgeted and actual costs. Variance ruleVariance ruleSpecifies the permitted minimum or maximum quantity of securities that can be delivered to satisfy a TBA trade. For Ginnie Mae, Fannie Mae, and Freddie Mac pass-through securities, the accepted variance is plus or minus 2.499999 % per million of the par value of the TBA quantity. ComvarianceComvarianceAn analogue to covariance for three variables. For three variables x, y, and z with values xi, yi, zi, i=1,…,n, the comvariance is com(x,y,z) = Si=1…n(xi-m(x))(yi-m(y))(zi-m(z)), where m(·) is the mean of the values in its argument. Due to Deardorff (1982). Mean variance criterionMean variance criterionThe selection of portfolios based on the means and variances of their returns. The choice of the higher expected return portfolio for a given level of variance or the lower variance portfolio for a given expected return.
