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: Two days after suffering a string of analyst downgrades, Cree (Nasdaq: CREE) took another beating, falling 12% after issuing worse-than-expected guidance for the current quarter.

So what: Cree and peer Veeco Instruments (Nasdaq: VECO) together took the brunt of Wall Street's bearish calls, which were based on overcapacity and poor pricing trends. Now it seems those fears have been realized.

Now what: In a statement issued yesterday, management told investors to expect $0.25 to $0.28 a share of profit -- well below the $0.34 analysts were calling for. Meanwhile, the sell-off has cut the stock to the point where Cree now sells for less than the long-term earnings growth analysts expect. Is that an opportunity? Or do you expect Cree's uninspiring growth trends to continue? Please weigh in using the comments box below.
