Shares of FuelCell Energy (FCEL 2.77%) jumped as much as 18.1% in trading today after the start-up of a new facility in California. Shares are up 12.6% as of 11:10 a.m. EST and have been fairly volatile in trading.
Late last week, FuelCell Energy announced the start of operations of a 2.8-megawatt fuel cell project in Tulare, California. This is one of the company's biggest projects, and it is supposed to be more efficient than previous plants. But while the operational milestone is great, it might not be what's driving the stock higher.
Late last week, FuelCell Energy's stock crossed above the $1 mark, which made stock traders take it a little more seriously. Stocks can trade in wild ways when they're low priced like this, and I think that's exactly what's happening today.
The $1 barrier isn't anything long-term investors should worry about, except to know that it can cause strange volatility in stocks. I would be more concerned about FuelCell Energy's continued losses and dilution of existing shareholders, as you can see in the chart below.
I am certainly not buying today's pop or the bounce of the last week. Shares can easily lose those gains and be back in penny-stock territory before you know it.
