Like all biotech investors, I bet you'd love to find the next Amgen (NASDAQ:AMGN) -- to be the whiz that picks the next biotech Rule Breaker. Back in January 1990, Amgen was available at a split-adjusted $1.07 per share. Right now, Amgen shares are going for about $60, which is more than a 50-bagger for long-term investors that held onto a great company. Anyone who invested $2,000 in Amgen 15 years ago, and held on, has a stake worth more than $110,000 today.

Of course, you'd like to buy the next Amgen. Who wouldn't?

This is my goal as well. I search for small biotech companies that are going to be tomorrow's industry leaders. I want the biotech companies that are going to deliver the groundbreaking drugs for Alzheimer's disease, cancer, multiple sclerosis, and all other diseases where current treatments are lousy. These patients need good drugs now! And this presents a great opportunity for the companies that are first movers developing these products. I want to invest in these companies and I want to do so at a reasonable price.

Destined to be the best
Finding these superb biotechs isn't a search for a once-in-a-lifetime opportunity. These great investments pop up a lot more frequently than you may think. The market features plenty of promising small caps with solid management teams and exciting drugs in development. Check out these five great investments over the last 10 years.

All of these companies are among the bigger, better-known names in the sector. But at one time, they too were obscure small caps that had yet to attract a following on Wall Street. Their stock prices reflected that, and this created a great opportunity for shrewd investors who moved ahead of the pack. I have to tell you that many opportunities just like this exist today.

The next big thing
The next five-, 10-, or 50-baggers are out there right now making tomorrow's great drugs. As Rule Breaker investors, we want tomorrow's Amgen because today's Amgen won't give us the kind of return we're looking for. Don't get me wrong, Amgen is still a great long-term investment for a conservative growth style. But to make the kind of investment that will rise more than 20 times in value over 10 years, we have to look to the small caps.

We have a broad universe of companies in which to conduct our search. Did you know that there are more than 250 publicly traded small-cap biotech companies to explore right now? The vast majority of them are unknowns. To me, that spells opportunity.

These companies, which are currently toiling away in obscurity, are developing new technologies and creating new drugs that are safer and more effective than anything available today. I strongly believe that these research labs will generate many breakthrough drugs. As an investor, I want to participate in this success.

Increasing our odds of success
The conventional wisdom is that small biotechs are speculative crapshoots that are very likely to blow up sooner or later. That they just must be riskier than big pharmas with actual products and earnings. Hogwash, I say! Merck's blowup this year demonstrates that companies of all shapes and sizes can be hazardous to your portfolio's health.

I will be the first to admit that not every small-cap biotech company is going to become a lasting success. Many are fated to permanently toil in obscurity, or even disappear. Only a select few are going to move on to become one of the great Rule Breakers. These companies have the following features that mitigate the risk of owning them, They:

  • Have strong balance sheets that allow the company to fully fund R&D;
  • Own proprietary technologies that give a unique edge over the competition;
  • Are designing drugs to fill unmet medical needs;
  • Are first movers with a superior product; and
  • Have superb management teams with proven track records.

Using the list above, we can identify quality companies with sound drug development strategies. It is these companies that spend money on R&D with the intent of getting the best return possible on that investment for shareholders. I will gladly tag along with management teams that have a clear goal of increasing shareholder value.

Not every company is going to be a resounding winner. In fact, the vast majority of them are deficient in some manner. Some of the major faults I come across are technologies that are unlikely to work, shaky balance sheets, incompetent management, or the fact that the company is just plain overvalued for what the company is positioned to deliver.

After screening these pretenders out, I am left with a select few that I believe are true Rule Breakers. These are companies that are going to not just beat the market over the next five years but also give it a sound spanking.
