Plug Power (Nasdaq: PLUG) Stock Gets Hit with a Dose of Reality

A disappointing earnings report sent Plug Power Inc. (Nasdaq: PLUG) stock as much as 9.5% lower today (Wednesday), as investors continue to take a more realistic view of the company's prospects.

The maker of hydrogen fuel cells, which reported its first-quarter results before the markets opened, said it had a loss of $0.06 per share, $0.01 more than analysts had expected.

Plug Power also reported a $68.4 million charge related to stock warrants. Including that one-time charge put Plug's loss at $0.57 a share.

Investors also weren't pleased that Plug's revenue fell 12.5% compared to the same period a year ago.

The poor earnings further dinged the already tarnished PLUG stock price, which has nosedived more than 60% since closing at $10.31 on March 10.

Plug Power is a classic case of a momentum stock that rocketed to startling heights only to crash and burn. One lesson investors can take from this saga is never to chase a momentum stock.

One year ago PLUG stock was trading at a mere $0.23 a share, and even as late as last December it was hovering around $0.80 a share.

Then the company started to attract attention by talking about expanding is fuel cell business from forklifts to other types of electric vehicles and by predicting profits in 2014.

By the time Plug Power announced in February that it had made a deal to supply Wal-Mart Stores Inc. (NYSE: WMT) with more than 1,700 of its new GenDrive fuel cell units, PLUG stock was on fire.

Just from December to March, PLUG shot up some 1,200% and was up about 4,300% from where it had been just one year earlier.

The problem is, Plug Power's fundamentals never supported such a huge spike in the stock price, and it should have been obvious that momentum had a major role in driving the price higher.

The bubble burst when a blistering report from Citron Research just after PLUG shares hit their 52-week high threw cold water on the company.

"The recent volume and share price surge in Plug Power demonstrates how Wall Street treats this stock: nothing more than a casino," Citron said. PLUG promptly fell 41% and has continued to slide ever since.

And yet while Plug Power isn't the wunderkind investors thought early this year, it's not necessarily a train wreck, either.
