Distribution of Market Equity

Below, Corrections displays the distribution of (log) market equity (price times shares outstanding) of the NYSE, NASDAQ, and AMEX in 2012 (click to enlarge).  As always, log means natural log.  Note that the graph would be essentially unreadable if it were transformed into levels:  the skew in market equity is very large.

The large cap nature of the NYSE is evident:  the breakpoint denoting the NYSE's 20th percentile is around the NASDAQ's 60th, and AMEX's 80th percentile.
