These procedure are the applying of mathematical steps instance variance and you can simple departure so you’re able to quantify new uncertainty out-of yields.

Remember that “uncertainty out-of returns” boasts not only the potential for losses, but in addition the odds of confident shocks prior to requirement. As the buyers usually be more concerned with bad unexpected situations than simply self-confident surprises, specific theoretical functions might have been complete having fun with measures you to definitely envision simply bad deviations in accordance with expectations. not, risk since the uncertainty away from yields, together with positive plus bad deviations regarding standard, is still a main exposure design utilized in both the theory and exercise off investing.
