Minimum variance frontierGraph of the lowest possible portfolio variance that is attainable for a given portfolio expected return.Minimum variance frontier Similar MatchesVariance 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 statistical measure of the degree to which random variables move together. A positive covariance implies that one variable is above (below) its mean value when the other variable is above (below) its mean value. 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. Variance minimization approach to trackingVariance minimization approach to trackingAn approach to bond indexing that uses historical data to estimate the variance of the tracking error. VarianceVarianceA measure of dispersion of a set of data points around their mean value. The mathematical expectation of the average squared deviations from the mean. The square root of the variance is the standard deviation.
