Amgen (NASDAQ:AMGN) is one of the truly remarkable success stories of the past quarter-century. Five-plus years after its IPO, Amgen was still a tiny company that had not yet scratched the surface of its potential. On Jan. 2, 1990, Amgen traded for $1.07. It now trades for more than $70.

That 6,400% gain illustrates the profit potential of investing in promising small companies. It also goes to show that if you want Amgen-like gains, you need to look for stocks trading around $1 per share -- or definitely below $5. Just take a look at this list of winners since 1990 and their stock price back then:

Microsoft (NASDAQ:MSFT)






Target (NYSE:TGT)



Pulte Homes (NYSE:PHM)



Say it with us: No, no, no!
Here's where we pull back the curtain: All of those Jan. 2, 1990, prices are adjusted for stock splits and -- in some cases -- dividends. While Amgen was a tiny company back in 1990, it still traded for $51 per share. Microsoft traded for $88, Oracle for $24, Target for $64, and Pulte Homes for $11.

So we hope we've done a little bit of myth-busting here. Namely:

  1. Lower-priced stocks do not go up any faster than higher-priced stocks.
  2. Lower-priced stocks are not necessarily cheaper than higher-priced stocks.
  3. Lower-priced stocks are not necessarily smaller than higher-priced stocks.

By itself, a stock's price cannot tell you anything about the value of the underlying company or its investment potential.

That's why Middleby (NASDAQ:MIDD), a stock that's returned more than 500% for subscribers to our Motley Fool Hidden Gems small-cap service, can remain a promising $900 million small cap even though it trades for north of $100 per share. It's also why Sirius Satellite Radio (NASDAQ:SIRI) can continue to look like an overvalued $5 billion money pit even as trades for $3.70.

OK, maybe "money pit" was a bit harsh
Myths about the meaning of stock prices abound, and catering to those myths may be one of the reasons Middleby's board is considering splitting the company's shares (or so we've been told). We encourage Middleby's leaders to stop worrying about the stock price, save the time and money required to file the necessary stock-splitting paperwork, and instead continue to focus on allocating capital efficiently and growing the business for the long term.

That's what shareholders should care about. If the business is succeeding, the stock will follow -- regardless of whether it's starting from $5, $50, or $500.

The Foolish bottom line
We readily admit that small companies, as measured by market caps of $2 billion or less, are for many reasons likely to offer better returns than large companies going forward. So if you're looking for stocks with the most potential for outsized returns, start with small caps -- you'll find that a more productive starting point than "low-priced stocks."

Also look for key traits of the market's biggest successes:

  1. Cheap valuations relative to a company's earnings or cash flows.
  2. Tenured managers who own a significant number of shares.
  3. Growing operations in a profitable niche.

And if you can find a company that meets these criteria, it's worthy of your research no matter the stock price.
