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 membrane maker Polypore International
So what: The Volt isn't selling as well as GM had hoped and the company will shut down production for five weeks, starting in March. That could put a dent in Polypore's sales because the company is believed to supply materials for the Volt.
Now what: Since Volts weren't exactly charging off the shelf I don't think this derails Polypore's long-term financial future. It may be a small blip in coming quarters, but if you have your eye on this stock, I see today as a buying opportunity. Shares are trading at less than 14 times 2012 earnings estimates right now, a nice value for a company expected to grow earnings.
