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 Titan International (NYSE: TWI) were up more than 11% today on heavier-than-normal volume.

So what: There's no news out there to indicate why the maker of tires and wheels for off-highway vehicles is enjoying the spike in price. Perhaps a fund or institution bought some shares, or maybe there's still some euphoria out there from last week's third-quarter earnings report. Or perhaps a rich Clash of the Titans fan simply likes the name and is starting to buy up the company (just kidding).

Now what: Given the unknown nature of the catalyst, it's not smart to make any investment decisions based on this movement. A random 11% pop should not dissuade or encourage you as you research the company.
