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 communications chip designer NXP Semiconductors (Nasdaq: NXPI) jumped as much as 12.6% in early trading today, eclipsing the stock's average daily trading volume in about 45 minutes.

So what: Google and Samsung revealed on Monday that the upcoming Nexus S smartphone will feature NXP's chips to facilitate near field communications (NFC), but the announcement didn't move NXP's stock at all. This could be a delayed reaction to that aging piece of news as investors wrap their heads around who benefits from this new product launch.

Now what: You can't even point to a short squeeze because NXP's stock isn't heavily shorted to begin with. The other plausible explanation for today's move would be that investors are becoming aware of NXP's existence thanks to the NFC connection. Yahoo! Finance reports zero analyst recommendations, reports, or estimates for this seriously underfollowed stock, despite a $4.3 billion market cap and $4.8 billion in annual sales.
