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 internet-communications company magicJack VocalTec Ltd. (NASDAQ:CALL) soared 26% today after its quarterly results and outlook topped Wall Street expectations.

So what: The stock had pulled back in recent weeks on valuation concerns, but today's Q4 results -- adjusted EPS of $0.69 blew out Wall Street by $0.28 as revenue surged 23% -- coupled with upbeat guidance are quickly putting those worries to rest. In a separate release, magicJack even said that it expects to open more than 10,000 incremental new retail locations in 2014, giving analysts plenty of good vibes over its longer-term growth prospects.

Now what: Management now sees full-year adjusted EBITDA of about $50 million on revenue of $158 million-$163 million, versus the consensus of $46 million and $142 million. "The transformation of magicJack is well under way and we expect our updated branding and expanding distribution channels to pay dividends as the year progresses," said President and CEO Gerald Vento. "The company remains well positioned to execute its growth strategy due to its strengthened balance sheet, nationally recognized brand, established customer base, high visibility distribution channels and low cost technology platform." Of course, with the stock busting through to a new 52-week high today and up more than 70% over the past three months alone, I'd wait for some of the exuberance to fade before jumping in.
