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 container leasing company CAI International Inc. (NYSE: CAP) jumped 15% today after announcing earnings.

So what: Revenue was up 9.4% to $54.6 million and net income fell 10% to $15.6 million, or $0.69 per share. The good news today is that expectations were even lower and earnings came in a penny ahead of Wall Street's guess.  

Now what: This past year was challenging for CAI, so sequential net income growth is a positive sign that the company's financials are improving. Shares are also trading at a low 7.1 times 2014's earnings estimates, even after today's pop. This isn't the best growth market and there are challenges ahead, but the value and leverage that investors are getting is attractive as economic activity picks up.
