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 logistics company Pacer International (NASDAQ:PACR) rose as much as 14% today after the company reported earnings.

So what: Third quarter revenue fell 28% from a year ago to $250.0 million, and was below the $258.2 million estimate. But earnings per share came in at $0.08, which was a penny better than estimates.  

Now what: On the surface the revenue decline looks extreme, but it's largely due to a new cross-border agreement with Union Pacific that doesn't require the company to pass rail transportation costs through its income statement. This will lower revenue and costs but shouldn't have a big impact on the bottom line. The adjustment made guessing earnings difficult this quarter, which is why investors are cheering the bottom line beat without worrying too much about the top line miss.
