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 satellite communications specialist Globalstar (Nasdaq: GSAT) jumped more than 10% in intraday trading on higher-than-average volume.

So What: When it comes to a small-cap like Globalstar, a one-day move like this can often be tough to pin down. With a low stock price and relatively low average volume, it doesn't take much buying action to put some serious pep in the stock. It is possible, though, that investors have been getting excited about the upcoming launch of Globalstar's second-generation satellites -- which is supposed to take place next Tuesday.

Now What: Globalstar is hoping that its second-generation satellites will help give it an edge over competitors like Iridium (Nasdaq: IRDM), so there's good reason for investors to look forward to the launch. Of course, while newer, better satellites could help the company's competitive position, it still needs to find a way to show its investors some positive cash flow.
