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 Syniverse (NYSE: NVR), which specializes in helping phone companies facilitate and bill roaming services for mobile users, soared 28% in intraday trading after investment firm The Carlyle Group agreed to acquire the company for $2.6 billion.

So what: This is Carlyle's second big bet this week. On Monday, CommScope (NYSE: CTV) confirmed executives are negotiating a deal in which Carlyle would take the company private at $31.50 a share. The stock soared more than 30% on the day.

Now what: Just as speculators have chased prospective buyouts in the wake of the bidding war for 3PAR, the coming weeks could easily bring big gains in undeserving telecom companies that loosely resemble Syniverse and CommScope.
