Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of OmniVision (Nasdaq: OVTI) surged more than 12% in early trading in anticipation of what most hope is a good earnings report tomorrow night.

So what: The maker of camera image sensors for the iPhone recently admitted that it wasn't the sole supplier to Apple (Nasdaq: AAPL), a surprise that left many investors cold. Even after today's action, the stock is down more than 60% year to date.

Now what: OmniVision has fallen so far, so fast that an anticipation rally is probably justified. The stock trades for less than half the long-term earnings growth analysts expect. I'm a shareholder, and I can't see selling at that price. What's your take? What you buy shares of OmniVision at current prices? Please weigh in using the comments box below.
