I assume that you, like everyone and his Aunt Avis, would love to find the next Procter & Gamble (NYSE:PG) -- to dig out the market's most precious Hidden Gems. Back in June 1970, Procter & Gamble traded at a split-adjusted $0.50 per share. Today, it trades at $55. Procter & Gamble has risen 110 times in value over the past 35 years, turning a $20,000 investment into more than $2.2 million. If you held P&G this entire time, your dividends today would be over $40,000, more than double than your original investment.

Of course, you'd love to buy the next Procter & Gamble.

But you'd prefer not to take on extreme risk, right?

I think you're smart to think that way. And so does a long list of great money managers -- from Peter Lynch to Seth Klarman, Jean-Marie Eveillard to Charles Royce. They've all searched for small companies with a mixture of sales and free cash flow growth, superior returns on invested capital, heavy insider ownership, and healthy assets -- all at a reasonable price.

Forever great
But remember, companies like P&G typically exhibit excellent financials from the day they hit the public markets. Procter & Gamble was never a penny stock (again, that share price of $0.50 back in 1970 is split-adjusted; the stock traded at $44 back then). Procter & Gamble -- Midwestern to the core -- didn't hype itself in press releases, nor did management make outlandish promises to its investors. It turns out that if you want to find monster long-term winners, you shouldn't throw money at shaky, speculative companies.

In 1970, Procter & Gamble's founding families (the company got its start as a soap and candle producer in 1837) owned massive stakes in the enterprise going back several generations, and they continued to run the company conservatively. This is a business that was run to sustain yearly profit growth indefinitely. If you're going to invest in small-cap rocket stocks, as we do together in Motley FoolHidden Gems, please avoid the whisper-stock party tips and hype jobs. They destroy wealth over time. Procter & Gamble was a minuscule firm compared to today, and yet it was not some moonshot "-tronics" company. Where are most of those today? Anywhere but the moon, you can bet.

And so, contrary to popular perception, you need not assume great risk to invest in the best small caps. You need only to train yourself to look for disciplined, conservatively run small businesses.

And finding these hidden gems doesn't involve a hopeless search through barn-sized haystacks for a lone platinum needle. The stock market features plenty of promising smaller companies run successfully by founders with large personal stakes in the enterprise. In fact, hidden gems thrive in every industry -- technology, finance, leisure, medicine, retail, and beyond. Take a look at these six great investments from 1990 to 2005, all of which were small caps in the early 1990s.

Note, again, that this group hails from a broad variety of sectors. Some are familiar consumer brands, while others are to this day largely unknown on Main Street. But each was a small cap 14 years ago. And not only weren't they industry stalwarts, but they were also largely unknown to consumers and investors. They had yet to attract a cadre of Wall Street analysts and big institutional investors.

And their stock prices reflected it. They were cheap because they were irrelevant!

They're what we search for together, every day, in Hidden Gems.

And these sorts of opportunities do exist today. Witness the 800% rise in the value of online closeout retailer Overstock.com since October 2002.

The next big thing
The 20- to 700-baggers of the next 15 years are out there right now, with their fuses lit and a wide-open sky above them. But they aren't Procter & Gamble. And they aren't Valero or IBM or General Electric. They're not companies valued in excess of $100 billion, covered by 39 Wall Street analysts.

They're small companies with strong founders and executive ownership north of 15%. Companies without debt concerns. Companies that generate excess cash from their operations, some of which already pay dividends. Companies that function without any real reliance on Wall Street for financing or table-pounding "strong buy" ratings.

I know it sounds contrary, but I want you to see that many of these small businesses offer low risk and high rewards for their long-term owners. How could a small company be less risky than a giant? Ask the former owners of WorldCom. Not only was that company overfollowed; it was also fraudulently run!

The exact opposite exists with great small caps. They're well-run and underfollowed on Wall Street, creating price inefficiencies that strongly favor long-term investors.

Does that sound possible? Does it sound logical? It's certainly contrary.

What I look for
Every day in Hidden Gems, we track down the following:

  1. Founders with large personal stakes.
  2. Financial statements that are easy to read.
  3. A solid asset base with little or no debt.
  4. Price ratios that significantly undershoot growth rates of free cash flow.
  5. Dominant positioning in a profitable niche.
  6. Plenty of room to grow.

If you're inclined to think that every small-cap stock is doomed to have a larger competitor stomp it out, I ask you to return to my list of strong performers above. Each rose from obscurity because of sound financial management and shareholder-friendly practices. The free markets gave them plenty of maneuvering room.

But because not every small company is poised for enduring success, I evaluate more than 100 of the 3,000-plus small-cap stocks each month -- all in search of one great Hidden Gems recommendation. As for the others, I find that 90% are too richly valued or too speculative, given the underlying business. That remaining 10%, however, leaves us with hundreds of small caps that will beat the market and dozens that will rise more than 30 times in value over the next 10 to 15 years.
