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 FuelCell Energy (NASDAQ:FCEL) jumped 16% today after reporting earnings.

So what: Revenue was up 22% to $44.4 million and net loss was $11.4 million, or $0.06 per share. Sales beat estimates and on an adjusted basis the company's loss of $0.04 per share were in-line with estimates.  

Now what: The market is rewarding companies who are considered growth stocks right now and FuelCell has done will by playing in a growth market. But I'll caution that they still haven't come close to reporting a profit and that's what it's all about at the end of the day. The other concerning number is backlog dropping from $428.3 million a year ago to $326.8 million on Jan. 31, 2014. There's just too much risk for me to buy in and I'd like to buy into a profitable company rather than take a risk on FuelCell today.
