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 SodaStream International (NASDAQ:SODA) jumped by more than 15% Friday after the company revealed through an SEC Filing it has entered into an agreement to make available PepsiCo's (NASDAQ:PEP) brands for use with its at-home carbonation systems.

So what: Specifically, the filing states, this will be a "small-scale, limited time test [...] scheduled for later this year." At the same time, SodaStream noted it's "exploring multiple relationships with other leading beverage brands."  But much to the chagrin of investors hoping for a Coca-Cola/Keurig Green Mountain-esque deal to transpire, the filing also insists, "There are currently no discussions between the Company and PepsiCo concerning any other form of broader business collaboration."

Now what: The news comes as welcome relief for weary SodaStream investors, for whom shares have still fallen more than 50% year to date even after today's pop. SodaStream's latest plunge came only a few weeks ago after the company issued disappointing preliminary results caused by weak demand for its soda makers and flavors in the United States. Even if today's news doesn't portend a potential acquisition down the road, the partnership with PepsiCo represents a much needed vote of confidence in the at-home carbonation concept SodaStream has championed for years.
