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 soda-machine maker SodaStream (Nasdaq: SODA) rose more than 18% in intraday trading today on heavier than average volume.

So what: Wall Street firm Oppenheimer & Co. put out a bullish note on SodaStream today, saying that it appears the company had a "successful holiday season" and that overall the launch of the product in the U.S. is going well. Oppenheimer has a buy rating on the stock and a $40 price target. In addition, SodaStream CEO Daniel Birnbaum was on CNBC this morning talking up the benefits of his company's device.

Now what: Considering that Oppenheimer's investment banking team was involved in SodaStream's IPO in November, it probably shouldn't be all that surprising that the firm has a positive view on the shares. It's definitely still a point of view to take into consideration, but it should also be taken in context. Meanwhile, my fellow Fool Rick Munarriz sees an opportunity for SodaStream to sell itself as a "green" product -- as opposed to a better-taste or convenience product -- but I remain skeptical. Americans have a love affair with their sodas, and it's highly doubtful that a home-brew machine will be able to shove Coca-Cola (NYSE: KO) or PepsiCo (NYSE: PEP) products from all but a smattering of U.S. households. My prediction? In the U.S. at least, after a brief buzz, SodaStream machines will gather more dust than converts.
