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 Trinity Industries (NYSE:TRN) jumped 10% today after the industrial service provider reported earnings.

So what: Fourth-quarter revenue was up 24% to $1.26 billion, while net income rose 58% to $112.8 million, or $1.44 per share, $0.03 ahead of estimates. For 2014, earnings per share are expected to jump to between $6.30 and $7, well ahead of the $4.75 EPS collected in 2013.  

Now what: Trinity Industries is benefiting from a shift to serving oil, gas, and chemical industries, which are seeing particularly strong demand in the U.S. That's also helped keep backlog high at $5 billion to end 2013. Shares trade at just 10 times the middle of 2014 estimates; with the momentum we've seen in recent quarters I think there's still room to run given the value investors are getting.
