The portfolios,
which are constructed at the end of each June, are the intersections of 5
portfolios formed on the ratio of book equity to market equity (BE/ME) and 5
portfolios formed on investment (Inv). 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.
The BE/ME breakpoints are NYSE quintiles. Investment 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.
The Inv breakpoints are NYSE quintiles. |
