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 RR Donnelley & Sons (NYSE:RRD) jumped 17% today after the company released earnings.

So what: First quarter revenue rose just 0.5%, to $2.54 billion, but that beat the consensus estimate of $2.46 billion. Net income dropped 33%, to $25.3 million, and on an adjusted level earnings per share of $0.37, beat estimates by $0.05.  

Now what: Net income is headed in the wrong direction, but the stock only trades at eight times this year's estimates, so there's value for investors. The one good sign for investors is that revenue guidance of $10.1 billion to $10.3 billion for 2013 was at the top end of estimates. I'd like to see a pullback in shares before jumping in, but I do think long-term shares can move higher.
