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 Ormat Technologies (NYSE: ORA) fell 10% today after the company released disappointing earnings.

So what: Revenue of $97.8 million easily passed estimates of $89.9 million in the quarter, but the bottom line wasn't so impressive. Analysts expected the company to earn a penny, but it reported a loss of $0.20 per share.

Now what: Foreign currency transactions hurt results badly in the quarter, with a $13.1 million loss. Without that, operating income increased from $2.2 million a year ago to $3.1 million this year. So there is a silver lining despite the stock drop today.

I'm optimistic on the long-term prospects, but I just don't see the company as a great value now, given today's disappointing results.
