A high, positive covariance value between two stocks implies that when the price of one goes up, that of the other usually does, too. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values (that is, the variables tend to show similar behavior), the covariance is positive. Whether you calculate sample or population variance. Gibt die Kovarianz einer Stichprobe zurück, d. h. den Mittelwert der für alle Datenpunktpaare gebildeten Produkte der Abweichungen.
