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 pre-paid debit card company NetSpend Holdings (Nasdaq: NTSP) were declined today and fell 36% after the company released earnings.

So what: In the second quarter revenue was up 10% to $74.4 million and earnings per share rose a penny to $0.08, but investors were expecting so much more. Analysts had expected $78.6 million in revenue and earnings per share of $0.11, so they were less than excited with the company’s growth.

Now what: To put salt in the wound, Barrington Research downgraded the company to market perform from outperform. The market is obviously freaked out today, and it was terrible timing to come out with a disappointing report. There is probably a bounce coming for shares but, after such a wild decline, guessing on when it will happen isn’t a bet I’d be willing to take.
