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 WiMAX wireless networking operator Clearwire (Nasdaq: CLWR) made a highly unusual move today, jumping as much as 13.6% on heavy volume in the middle of the day.

So what: While it is earnings season, fantastic reports tend to affect stock prices right at the opening bell. This jump, however, stems from a Bloomberg report pouring good financial news over Clearwire during lunchtime.

Now what: The report says that Deutsche Telekom (NYSE: DT) subsidiary T-Mobile USA might sell $2 billion worth of cell towers in order to finance the purchase of some wireless spectrum licenses from Clearwire. Nobody expects a bidding war as AT&T (NYSE: T) and Verizon (NYSE: VZ) already have all the wireless spectrum they need, and Sprint Nextel (NYSE: S) would essentially be buying Clearwire licenses from itself. $2 billion would go a long way toward shoring up Clearwire's flimsy balance sheet, though the company still needs to figure out how to turn a profit and stop burning cash.
