Protalix BioTherapeutics Shares Plunged: What You Need to Know

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 clinical-stage biopharmaceutical company Protalix BioTherapeutics (ASE: PLX) are swooning 12% today after the company announced a secondary share offering after the bell yesterday.

So what: In order to finance its clinical research, Protalix needs cash -- and apparently that means at any cost. The company is pricing 4.5 million shares at $5.25, which is significantly below yesterday's close of $6.13.

Now what: To me, this doesn't seem like rocket science. Protalix doesn't have an approved drug and has been losing money for more than a decade now. Even worse, this isn't the most egregious abuse of a secondary offering Protalix has brought to the table. In October 2007, Protalix priced 5 million shares at $5, more than an 85% discount to the previous day's closing price. With a share count that has more than quadrupled over the past five years, Protalix continues to show that it doesn't care much about its investors, and, as such, I continue to view it as one of the worst investments in the biotech sector.
