Today, my search continues for some great small- and mid-cap stocks to add to my real-money "multivitamin" portfolio. Last week, I revealed the results for this month's Foolish 8 screen and came up with seven candidates. Today, we turn to the Modified Foolish 8.

Mod squad
For a refresher, here's a summary of the changes I made to turn the Foolish 8 into the Mod-8:

  1. Raised the revenue cap to $900 million or less.
  2. Took the $25 million limit off the daily dollar volume requirement, making it simply $1 million or greater.
  3. Loosened the relative strength requirement to 50 or greater.
  4. Required not only positive cash flow, but also positive free cash flow.
  5. Required a price to free cash flow-to-cash flow growth (PFCF-to-FCF growth) multiple of 1.00 or less.
  6. Required better than 15% return on equity (ROE) over the past four quarters, and for each of the past three fiscal years.

According to the independent American Association of Individual Investors, the Mod-8 recorded a 1,002% total gain from January 1998 to December 2010, for an outstanding 20% annual growth rate. (Disclaimer: The AAII methodology involves buying a stock the month it appears on a screen and selling when it's off -- something we'd never do. Still, this performance points to the screen's strong potential.)

Only three companies pass the screen this month.
