Magic Formula Investing (MFI), as described by hedge fund manager Joel Greenblatt in The Little Book that Beats the Market, consists of ranking stocks by earnings yield (cheap) and return on capital (quality), adding the rankings together, and buying from the resulting lists. Below are stocks that have moved into, and dropped out of, 3 of the MFI screens used by MagicDiligence.

As usual for pre-earnings season, the movement in the screens was slight last week. Most of these names have clearly lived on the fringes of the screens, dropping in and re-entering almost week-to-week. As I glance through the list, in fact, no truly "new" names entered last week.

This will change soon, however! Earnings season for Q1 kicks into full gear starting next week, and I expect to see some major movement over the next few weeks. Hopefully we get some interesting new stocks to dig into.
