What: Shares of Colfax (NYSE: CFX) jumped 13% today after the company blew away earnings expectations.

So what: It was an earnings trifecta for Colfax when the company reported sales, earnings, and outlook that topped expectations. Sales reached $186.7 million, earnings per share of $0.32 topped estimates by $0.06, and 2011 earnings guidance was raised to $1.20, to $1.26 per share.

Now what: Sales grew an incredible 52% this quarter, and for the full year the company increased growth guidance to 9% to 11%. At the low end of 2011 estimates, shares now trade at 22 times this year's earnings and momentum looks to be continuing. I think shares have room to run, but I'd like to see an even better value before pushing all of my chips into the stock.
