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, Inc. (NASDAQ:FCEL) jumped as much as 12% today after announcing a large order.

So what: POSCO Energy is ordering 5.6 MW of fuel cell modules, in addition to monthly orders as part of a long-term 122 MW order. The companies will also expand their partnership in an effort to collaborate on international sales, build efficient supply chains, and reduce costs.  

Now what: POSCO is also FuelCell's largest shareholder so advancing the partnership isn't all that surprising. I also don't see the 5.6 MW sale turning the company profitable, which is the biggest challenge in the fuel cell business. We've seen pops and drops on good and bad news for FuelCell Energy, but until the company can make a profit and quit diluting shareholders with constant dilutive stock offerings, I'll stay out of the shares. The promise that deals like this present simply don't turn into financial results.
