The portfolios, which are constructed at the end of each June, are the intersections of 2 portfolios formed on size (market equity, ME) and
2 portfolios formed on profitability (OP). The size breakpoint for year t is the median NYSE market equity at the end of June of year t.
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 t-1. The OP breakpoint is the median of OP for NYSE stocks. |
