The portfolios,
which are constructed at the end of each June, are allocated to two Size groups (Small and Big) using
NYSE median market cap breakpoint. Stocks in each Size group are allocated independently to four B/M groups
(low B/M to High B/M for fiscal year t-1) and four Inv groups (Low Inv to High Inv for fiscal year t-1)
using NYSE quartile breakpoints specific to the Size group.
BE/ME for June of year t is the book equity for the last fiscal year end in t-1 divided by ME for December of t-1.
Inv for June of year t is the change in total assets from the fiscal year ending in year t-2 to the fiscal year ending in t-1, divided by t-2 total assets.
