How Risky Is Shopify Inc. (U.S.) Stock?

The story is pretty amazing: Snowboarder tries to start his own snowboard company; when he tries to build an e-commerce presence, there are no options he likes, so he makes his own; over time, that business outshines the snowboards; eventually the company is taken public.

In a nutshell, that's what happened to Tobias Lutke, founder and CEO of Shopify (NYSE: SHOP). The company offers a subscription platform to help small and medium-sized businesses build sales channels across the Internet, as well as merchant services focused on payment and shipping solutions. Shares of the relatively young public company are up almost 400% since February 2016.

That has a lot of investors asking: How risky is this stock?
