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: Drilling contractor Nabors Industries (NYSE: NBR) saw its shares shoot 10% higher today after the company released earnings.

So what: Revenue jumped from $1.4 billion a year ago to $1.84 billion and topped analyst estimates. Earnings per share fell a penny short of estimates at $0.49, but investors were apparently willing to overlook that today.

Now what: The market has been worried about a decline in the pressure pumping business because of a reduction in natural gas fracking, but Nabors appears to be weathering the storm. Management said that existing contracts would give the pumping unit a "respectable" year and high oil prices would keep demand high for the company's other products. Trading for under $17 and a forward P/E ratio of 6.5, the shares look attractive right now, and I think this is a great time to buy.
