The portfolios,
which are constructed at the end of each June, are the intersections of 10 portfolios formed on size
(market equity, ME) and 10 portfolios formed on profitability (OP).
The size breakpoints for year t are the NYSE market equity deciles 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 breakpoints are NYSE deciles. |

|
Please be aware that some of the value-weight averages of operating profitability for deciles 1 and 10 are extreme. These are driven by extraordinary values of OP for individual firms. We have spot checked the accounting data that produce the extraordinary values and all the numbers we examined accurately reflect the data in the firm's accounting statements.
