Minimum variance frontierGraph of the lowest possible portfolio variance that is attainable for a given portfolio expected return.Minimum variance frontier Similar MatchesComvarianceComvarianceAn 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. Mean variance analysisMean variance analysisEvaluation of risky prospects based on the expected value and variance of possible outcomes. 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. CovarianceCovarianceA measure of the extent to which two economic or statistical variables move up and down together. For two variables x and y with values xi, yi, i=1,…,n, the covariance is cov(x,y) = Si=1…n(xi-m(x))(yi-m(y)), where m(·) is the mean of the values in its argument.
