OSI Systems (NASDAQ:OSIS) sure covers a lot of high-profile ground for a small cap: medical imaging, homeland security, and optoelectronic devices. The company reports fourth-quarter earnings tomorrow morning, so let's see how all that high-flying gadgetry adds up.

What analysts say:

  • Buy, sell, or waffle? Five out of six Wall Street analysts want to buy this stock, and the sixth prefers a hold rating. In our Motley Fool CAPS database, it's a five-star market general, with a 98% approval rating among 93 of your fellow Fools.
  • Revenue. The analysts expect $153.3 million, on average. That's 22% more than last year's $125.6 million. OSI has already reported $152.7 million in preliminary revenue, though.
  • Earnings. The average projection points to about $0.20 per share in pro forma profits, up from $0.04 per share last year.

What management says:
In the third-quarter earnings release, CEO Deepak Chopra said that the order backlog is stronger than ever, thanks to new business in the security segment, and that the ongoing cost-cutting projects should be completed by the end of the fiscal year. That would be right now.

Also, there's a fresh influx of loans to fuel operations. That will be important in order to fund the year-to-date operating shortfall of $8.2 million.

What management does:
It's a rocky road, as you'd expect from a small cap with a lumpy revenue flow and unpredictable bottom-line results. Also, keep in mind that these are GAAP margins, not the adjusted pro forma numbers the analysts like to predict. But sales are growing at a remarkably steady clip, and the company has increased its R&D spending -- and thus its reinvestment in the future -- in each of the last six quarters. That, to me, is a more optimistic trend than any whiz-bang accounting tricks could ever conjure up, especially for a small and growing business.

One Fool says:
Being Swedish, I can't help but chuckle at the ticker symbol a bit. "Osis" means "tough luck" in my native tongue, though it doesn't sound like an apt description of the situation for OSI shareholders today.

The stock is up some 28% over the past 12 months, easily outpacing the S&P 500. On the other hand, L-3 Communications (NYSE:LLL) is running neck-and-neck with its smaller rival, and Rule Breakers pick American Science & Engineering (NASDAQ:ASEI) has coughed up a 51% gain over the same period.

I realize that none of these companies are direct competitors to OSI, simply because of the diversity of its operations. It's a microconglomerate, kind of like Otter Tail (NASDAQ:OTTR), but based around advanced electronic systems rather than power generation. It's striving to be more like a mini-Philips (NYSE:PHG) or a micro-Lockheed (NYSE:LMT), compared to Otter Tail's General Electric (NYSE:GE) aspirations.

But while that makes it tough to draw direct comparisons to peers and rivals, it's also a double shot of instant respect. For one, getting exposure to multiple high-growth markets in one stock is instant diversification, and if one gambit makes it, the other two may end up irrelevant. For another, every stock mentioned in this roundup carries a four-star CAPS rating or higher, placing OSI in well-regarded company.

Now, neither medical systems, contraband scanners, nor advanced optoelectronics look ready to blow up overnight. The company is still unprofitable, and operating cash flow is negative. But for a long-term investor willing to take a few chances for a potentially large payoff in a couple of years, this could be a tempting pick. Tomorrow's results will largely be signal noise; Fools should look for news on what really matters to OSI, including order development, growing its customer base, and launching compelling products.
