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 human enzyme development company Halozyme Therapeutics
So what: Cinryze, ViroPharma's
Now what: As you can see by Friday's action, the FDA's ruling has considerably more bearing on the unprofitable Halozyme than it does on ViroPharma, whose Cinryze is already pumping out profits. As for me, I'm not nearly as excited about the news -- at least not as excited as investors seem to be. In December, I noted Halozyme's lofty valuation as a reason to avoid the stock, and I'm sticking with that assertion even today. With losses expected well into 2014 and possibly beyond, I see little reason to chase Halozyme higher.
