There was not a whole lot of movement in the Magic Formula® Investing (MFI) screens this week, but there were two new names we haven't seen in 2015.

You remember TiVo, right? Years ago, the company pioneered the digital video recorder (DVR), and forever changed the way people consume television.

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.

For a company that has consolidated and dominated its retail niche, GameStop sure gets no love.

SanDisk has come way down after a disappointing outlook, and now screens as one of the top #50 MFI stocks.

Below are stocks that have moved into, and dropped out of, 3 of the MFI screens used by MagicDiligence.

The stock at $12.50 is in the bottom part of its 52-week range, 64% under its 52-week high. Assuming reasonable 6-7% growth going forward, and a 10% earnings yield, I see Fonar worth about $17.50/share - 40% upside from here.

Discovery has a lot of really nice attributes that make it one of the highest quality media companies in the MFI screens right now. But the key question is: is the price right?

I like Crown Media's business and trends, and the stock looks like a reasonable buy at present. Currently at an 11% earnings yield, it trades below its 5-year average of 10% and the industry average of about 9.5%.

There was a fair bit of movement in the Magic Formula screens this week, although practically all of these stocks have been in-and-out of the screens over the past several months.

In the history of Magic Formula Investing, there has been no more consistently screened stock than Microsoft. This blue chip tech stalwart has been a part of the screens almost since the day they were launched in 2006. With a recent share price decline, is this great business cheap again?

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).

Sanderson has seen its gross margins expand to almost 19%, vs. a 5 year average of 9%. Pilgrim's Pride has had even better success, upping its gross margins to 14.5%, vs. a 5 year figure of 5%.

Merger arbitrage is a nice investing tool to carry on one's belt, as attractive opportunities do come along fairly often and the risk/reward involved with them is normally in the investor's favor.

When reviewing a deep value screen like Magic Formula® Investing (MFI), it always piques the interest to discover a company that has 5-year compound annual revenue growth of 34% and operating income growth of 112%!
