The portfolios,
which are constructed at the end of each June, are the intersections of 5 portfolios formed on size
(market equity, ME) and 5 portfolios formed on net share issues (NI).
The size breakpoints for year t are the NYSE market equity quintiles at the end of June of year t.
NI for June of year t is the change in the natural log of split-adjusted shares outstanding
from the fiscal yearend in t-2 to the fiscal yearend in t-1. The NI breakpoints are NYSE quintiles. |
