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: Lexmark (NYSE: LXK) popped 21% in intraday trading today after the company printed better-than-expected quarterly results.

So what: Non-GAAP EPS of $1.36 trounced the $1.03 consensus estimate and rose 11% year-over-year. Revenue rose a more modest 1% to $1.04 billion, ahead of the consensus forecast of $1.01 billion.

Now what: The printer business is a razor and blade model in which the printer is the razor and the ink or toner is the blade. Lexmark is preparing to exit the less-profitable low-end inkjet market. During the quarter, revenue growth in strategic focus areas was more than 25% for managed print services and in the double-digits for core supplies (like ink and toner). Management guided GAAP EPS for the current quarter to $0.94 to $1.04, straddling the consensus estimate of $0.99. At a P/E ratio of less than seven times, this stock just might print big wins for shareholders.
