Variance is a statistical tool measuring the dispersion of a variable from its mean. Variance is equal to the sum of the squares of the deviation of each return from expected outcome, weighted by the likelihood of each of the possible returns occurring. Applied to financial profitability, variance measures the risk of a financial security.
