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 Stratasys (Nasdaq: SSYS) soared more than 13% to an all-time high after the company blew away fourth-quarter estimates for revenue and profit.  

So what: High demand for Stratasys' 3-D printing and production technology helped the company post an 80% increase in profit on a 29% increase in revenue. Analysts were $0.03 low in their fourth-quarter earnings estimates, Reuters reports.

Now what: No doubt investors loved the fourth-quarter beat, but today's outsized gain may have more to do with the year ahead. CEO Scott Crump said in the earnings release that accelerating fourth-quarter revenue growth "bodes well" for 2011.

If he's right, it also bodes well for today's buyers.
