Certainly, the concept of skewness of returns and its role in the context of portfolio analysis has gained increasing attention in recent literature. Witness the studies by Alderfer and Bierman, Arditti, Jean, and Simonson. Each of these studies has treated skewness as the third moment of a series expansion—accordingly, skewness has been measured and interpreted as a logical extension of the traditional two-dimensional return-versus-standard deviation analysis of security evaluation. The purpose of this note is to illustrate that the measurement of skewness is more sample sensitive than similar measurements for the mean and standard deviation. In particular, skewness measures will be shown to be highly sensitive to both the size of the differencing interval and the initialization point. [ABSTRACT FROM AUTHOR]
