On CAPS, 20% of the 432 members who have rated SodaStream believe the stock will underperform the S&P 500 going forward. These bears include Jeffrey2012 and TarynOne.

A couple of months ago, Jeffrey2012 touched on SodaStream's seemingly unsustainable valuation: "Give me a break. Expensive fad company who faces increasingly difficult sales comps going forward."

In fact, SodaStream trades at a forward P/E of 24. That represents a clear premium to more conventional, dividend-paying soda plays like Coca-Cola (NYSE: KO) (16), PepsiCo (NYSE: PEP) (14), and Dr Pepper Snapple (NYSE: DPS) (12).

CAPS member TarynOne elaborates on the SodaStream bear case:

From a consumer's perspective, this stock will eventually come down from it's honeymoon period. Apart from food/soda "hobbyists" that would happily pay up for the novelty of making your own soda drink, the average soda lover will soon realize that ready-made soda is the cheapest and easiest option. It may take some time for the novelty to wear off though because I must admit carbonating your own soda does sound pretty cool.
