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 portable storage company Mobile Mini (NASDAQ:MINI) rose 11% today after reporting earnings.

So what: Third-quarter revenue rose 6% to $100.9 million and net income rose 35.4% to $12.9 million. On an adjusted basis, that translated to earnings per share of $0.29, well ahead of the $0.22 analysts expected.  

Now what: The numbers were pretty strong across the board for Mobile Mini, and the company is leveraging capacity, which will expand the bottom line. Utilization was up to 60.6% from 57.7% last quarter, and it looks like the numbers will stay strong in the fourth quarter. The stock is trading at 17 times forward earnings, which is a little too expensive for my blood, but I wouldn't be a seller as a long-term shareholder today.
