3 Stocks That Have Doubled and Still Have Room to Grow

Owning a stock that's doubled in value in just a year's time is certainly cause for celebration, but seasoned investors know to weigh explosive performance against the potential for continued gains. It's a time-tested reality that what goes up often comes down.

On the other hand, truly great companies tend to keep winning and can present investment opportunities that create life-changing returns over the long term. With that in mind, we asked a panel of Motley Fool investors to profile a stock that gained at least 100% in 2017 and still has gas in the tank. Read on to see why they identified Control4 (NASDAQ: CTRL), Shopify (NYSE: SHOP), and Take-Two Interactive (NASDAQ: TTWO) as companies that are primed to keep their big winning streaks alive.

This small e-commerce platform continues to make big gains

Chris Neiger (Shopify): Shopify is a cloud-based e-commerce platform that allows small and medium-sized businesses set up online shopping, track shipments, publish their own blog posts, and even manage inventory -- and over the past 12 months, its share price has skyrocketed 144%.

Shopify is doing so well right now because the company is experiencing phenomenal user growth and solid top-line increases. The company had about 200,000 merchants using its platform two years ago but now boasts more than 500,000 merchants from 175 countries. All of that growth has helped spur the company's sales, and in the third quarter Shopify's top line popped 72% year over year. The company is seeing the overall dollar value of online sales made through its platform increase as well. Transactions conducted through Shopify hit $6.4 billion in the third quarter, a huge 69% jump year over year.

But aside from its impressive customer and top-line growth, Shopify also has a massive trend on its side. Online shopping is still a fast-growing market, and many small and medium-sized businesses need platforms like Shopify to get them up and running. Retail e-commerce sales are expected to reach $638 billion in 2022, up from $409 billion in 2017. Shopify's already entrenched in the e-commerce space, and any expansion in this market should help build on the company's current position.

Citron Research, which often releases negative research about companies, said in October that it questioned Shopify's customer growth and said that many of the company's small business customers will eventually fail, leaving Shopify with less clients. Shopify addressed the report and said that it defends its business model. And while it's a certainty that some of Shopify's clients will fail at their businesses and leave its platform, the fact remains that Shopify continues to add new clients to replace them and is already proving that it can grow its sales from that customer expansion. If the company continues on this trajectory, then it's easy to believe this stock could easily double once again.
