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 home beverage carbonation system specialist SodaStream International (Nasdaq: SODA) climbed 11% in intraday trading Friday on above-average volume.

So what: The red-hot shares are setting yet another all-time high with the move and are now up a whopping 180% since going public in November. There doesn't seem to be any company-specific news driving today's double-digit pop, but given the fact that nearly half of SodaStream's shares are being shorted, we could simply be witnessing a "squeezing" effect of sorts.

Now what: I'd continue to keep my distance from SodaStream. The market for home soda makers may be a big one, but with the stock sporting a lofty forward P/E of 50, I'm just not ready to bet on any kind of mainstream acceptance just yet. Of course, given the wild success of Green Mountain's (Nasdaq: GMCR) Keurig maker -- and the wild returns that have followed -- the SodaStream story is most definitely worth following.
