It looks like Mr. Market has picked up on my enthusiasm for camera-chip specialist OmniVision Technologies (Nasdaq: OVTI). In fact, I think he got a little too fired up about this stock lately.

OmniVision just reported fourth-quarter earnings, and it was a fine quarter indeed:

  • Sales jumped 64% year-over-year to $258 million. That's at the top end of management guidance and $4 million better than the analyst consensus.
  • $0.66 of non-GAAP earnings per share was an astronomical leap from $0.18 seen a year ago, and it was also a penny ahead of Street expectations.
  • The outlook for next quarter places a revenue midpoint slightly below analyst estimates, but as we saw this quarter, Omnivision tends to land at the high end of its guidance.
  • Management expected gross margins to stay steady at about 29.8% in GAAP terms. The final tally was 30.7%, which is a significant improvement on the back of a richer product mix.

In short, the company beat every target it had set up. The Backside Illumination, or BSI, sensor chip structure is every bit the cash-cow selling point I expected it to be.

While the rest of the industry shrugged BSI off as impossibly expensive, OmniVision forged ahead and created a competitive advantage by making the technology not only better than traditional chips but also cost-effective to manufacture. OmniVision is still many moons ahead of Sony (NYSE: SNE), STMicroelectronics (NYSE: STM), former Micron (Nasdaq: MU) division Aptina, and other camera chip makers who are no doubt playing catch-up as we speak.

Now, OmniVision shares swooned after this report hit the wires, like a Hollywood diva angling for her close-up shot. The only reasonable explanation for that move is that investors had expected even more. I guess you can't get a 44% earnings surprise every quarter.

Even so, an 11% three-month price jump is nothing to sneeze at and works out to a market-bashing 52% or so if sustained through four quarters. The stock has beaten fellow Apple (Nasdaq: AAPL) coattail-rider Cirrus Logic (Nasdaq: CRUS) in both the one-quarter and full-year perspectives, not to mention crushing Apple itself.

The only company I can think of that can match OmniVision's technological moat today is robotic surgery specialist Intuitive Surgical (Nasdaq: ISRG), which locked down its market with patents and FDA approvals to the point of being bulletproof. There's one other consumer-oriented technology that comes close, as detailed in this free report.
