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 investment thesis.

We aren't prone to giving much attention to short-term stock movements here at The Motley Fool.  We like focusing on a years- or decades-long investing horizon and drowning out all of the unnecessary noise in the process.

But none of us is super-human, and it's worth acknowledging that really big short-term movements might cause our heart rates to speed up. It might also lead us to make some ill-advised investing decisions. That's why it's worth pointing out stocks that might be making big moves.

In the following video, Motley Fool contributor Brian Stoffel talks about one stock that could make big moves this week. Last week, the three stocks he identified moved an average of 12% following their earnings release. Listen in to find out which stock could be this week's biggest mover, and what long-term investors should really be paying attention to.
