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 Green Dot (NYSE: GDOT) fell by as much as 10% today after the company released disappointing earnings.

So what: Earnings fell a penny short of expectations at $0.39 per share, but the company did boost the full-year outlook: Green Dot now expects revenue between $490 million and $505 million, while EBITDA is expected to fall between $117 million and $123 million.

Now what: The earnings miss was not dramatic, so I wouldn't be panicking today. Still, shares are trading at an 18.6 forward earnings multiple, so the stock isn't a screaming value despite today's drop. I'll sit out today's move despite the rally in shares later in the day.
