Construction: 

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 t1) and four OP groups (Low OP to High OP for fiscal year t1)
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 t1 divided by ME for December of t1.
OP for June of year t is annual revenues minus cost of goods sold, interest expense, and selling, general, and administrative expenses
divided by book equity for the last fiscal year end in t1. 



Stocks: 

The portfolios
for July of year t to June of t+1 include all NYSE, AMEX, and NASDAQ stocks for which we have
market equity data for June of t, (positive) book equity data for t1,
nonmissing revenues data for t1, and nonmissing data for at least one of the following:
cost of goods sold, selling, general and administrative expenses, or interest expense for t1.
