Webthe importance of higher moments appears to be economically material and statistically significant in optimization • We will illustrate two broad approaches to incorporate higher moments into portfolio optimization. – Our first approach will use “full scale” optimization that explicitly includes skew and kurtosis in the objective function. WebRecall that the second moment of X about a is 𝔼((X−a)2). Thus, the variance is the second moment of X about μ=𝔼(X), or equivalently, the second central moment of X. Second moments have a nice interpretation in physics, if we think of the distribution of X as a mass distribution in ℝ. Then the second moment of X about a is the moment of
