In the matter of just a few years, “the Cloud” has evolved from the new feature that your grandmother just can’t quite seem to understand to one of the main factors driving growth in the technology sector. Cloud computing is now an essential focus for software-related companies, and cloud stocks have piqued the interest of many tech-focused investors.

New technologies and changing consumer behavior have changed the shape of the technology landscape, and an industry that was once centered on the personal computer has adapted to survive in the world of mobile computing and the Cloud. The markets have been paying attention, and some of the best tech stocks have been those that are either primarily cloud-based companies, or those that have shown growth in their cloud operations.

With this in mind, we’ve highlighted three stocks that are not only showing strong cloud-related activity, but also strong fundamental metrics. Check out these three cloud stocks to buy right now:

1. Five9, Inc. (FIVN – Free Report)

Five9 provides cloud software for contact centers. The company offers software products such as workforce management, speech recognition, predictive dialer, and voice applications, as well as an all-in-one contact center cloud platform. Currently, FIVN holds a Zacks Rank #2 (Buy).

Five9 is still a loss-making company, but it recently surpassed our Zacks Consensus Estimate by 40%, and we’ve seen four positive revisions for its full-year and current-quarter earnings since then. Also, sales are expected to grow by nearly 20% this year and next year. Furthermore, the stock has slumped in the industry-wide tech pullback, which means investors may have a chance to buy at a discount right now.

2. Exa Corporation (EXA – Free Report)

Exa is a developer of computer-aided engineering simulation software, primarily in the fluid dynamics space. Over the past couple of years, the company has emerged as a cloud player thanks to its ExaCLOUD platform, which gives customers access to its entire simulation suite via a web browser. EXA is currently a Zacks Rank #2 (Buy).
