SpletWhile risk in the accumulation phase is often summed up by volatility, the central focus in the distribution phase becomes shortfall risk, or the risk of outliving your money. … Spletity is a desirable property for a risk measure, even if exceptions exist, as discussed below. Subadditivity ensures that the diversiﬁcation principle of modern portfolio theory holds since a subadditive measure would always gen-erate a lower risk measure for a diversiﬁed portfolio than a non–diversiﬁed portfolio.
