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 equipment maker Geospace Technologies (NASDAQ:GEOS) jumped 18% today, after the company released earnings.

So what: Fiscal first quarter revenue jumped 80%, to $77.8 million, easily topping the $66.1 million that analysts expected. Net income jumped 153%, to $22.0 million, or $1.70 per share, also well above the $1.18 analysts expected.  

Now what: The company's wireless and reservoir products are driving the way, and look to continue strong results in coming quarters. With massive growth both on the top and bottom line, I think the stock still has a lot of room to run higher. Shares only trade at 18 times next year's earnings estimates. and they may be bumped up after this earnings beat.
