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: Software optimization specialist Compuware (Nasdaq: CPWR) saw its shares take a 10.1% haircut today on more than three times the average trading volume.

So what: Compuware's third-quarter report put a stop to five months of steadily rising share prices. The earnings miss was small, sales exceeded expectations by a small margin, and management said it was "comfortable" with current Street forecasts for the coming quarter and year.

Now what: Sometimes nothing short of a beat-and-raise will satisfy Mr. Market. Compuware is on a healthy path with steadily improving margins and little competition in its core markets. Today's pullback could be a great opportunity to open a position in this four-star CAPS favorite.
