edit:
really naively, looking at stock metrics without any knowledge of what a sodastream business is and how a sodastream business might perform in the future, the stock looks very expensive now compared to historical earnings or current book value ( CAPE > 100 (?!), price / tangible book value > 5 ). Then again, it would have looked really expensive to me a couple of months ago before the stock price shot up -- i assume that was a reaction to news that pepsi co was going to acquire it, or at least seriously thinking about an acquisition.
