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 mobile data management expert Synchronoss Technologies (Nasdaq: SNCR) jumped as much as 24.5% this morning on tremendously heavy volume.

So what: Last night's second-quarter report just edged out analyst estimates, with 40% earnings growth on 49% higher non-GAAP revenues, but then management also raised its full-year guidance on both the top and bottom lines. The stock has now gained 82% in the last year and tripled over two years.

Now what: Synchronoss shares are crushing rivals CSG Systems (Nasdaq: CSGS), Amdocs (NYSE: DOX), and NeuStar (NYSE: NSR) with impunity, and it's all thanks to rampant revenue growth. The company has recently expanded its relationship with Verizon (NYSE: VZ), AT&T (NYSE: T), and Vodafone (NYSE: VOD), which should keep those sales gushing for the foreseeable future. Mind you, the stock trades for a nosebleed-inducing 400 times trailing earnings, so owning Synchronoss shares might not be good for your heartburn.
