The third column shows the correlation between EU and f(E, V) for a sample of annual return on one-stock “portfolios”. The correlations are clearly less than for the diversified investment company portfolios of the second column. The fourth column again considers undiversified, single stock portfolios, but this time for monthly holding period returns. The correlations are much higher than those of column three, usually as high or higher than those in column two. Thus, for the investor who revises his or her portfolio monthly, even for portfolios whose returns were as variable as those of individual stocks, f(E, V) would be highly correlated with EU for the utility functions considered.
