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 Quad/Graphics (NYSE:QUAD) jumped as much as 12% after the company released earnings.

So what: Sales jumped 14% to $1.3 billion and the company swung to a loss of $14 million, or $0.31 per share. After adjustments, earnings were $0.05 per share, but that was still well below the $0.15 estimate from analysts.  

Now what: What eased any worries for investors was that management reiterated previous earnings guidance for 2013 and a solid beat on the top line. Analysts were expecting $1.15 billion in revenue, so the company did beat on that level. I think shares can outperform as revenue grows and management pushes some of that extra revenue to the bottom line.
