Today, my search continues for some great small- and mid-cap stocks to add to my real-money "multivitamin" portfolio. Y esterday, I revealed the results for this month's Foolish 8 screen and came up with five 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:

  • Raised the revenue cap to $900 million or less.
  • Took the $25 million limit off the daily dollar volume requirement, making it simply $1 million or greater.
  • Loosened the relative strength requirement to 50 or greater.
  • Required not only positive cash flow, but also positive free cash flow.
  • Required a price-to-free-cash-flow-to-cash-flow growth (PFCF-to-FCF growth) multiple of 1.00 or less. I have tweaked the screen to use actual FCF growth over the past year.
  • Required better than 15% return on equity 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 gained more than 1,000% from January 1998 through February 2011, for an outstanding 22.1% average annual growth rate. The S&P 500 averaged 2.4% over that period. (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 two companies pass the screen this month.

Onward and downward
In the coming days, I'll take a close look at these companies, as well as the small caps that passed yesterday's Foolish 8 screen. I'll soon report back on whether any of them are a good fit for my portfolio.
