Zix Corporation (ZIXI)

Zix is an email provider. It focuses on secure messaging, marketing itself to corporate and government entities. The unique approach of encryption, coupled with avoiding downloading, makes this an attractive service.

With sales rising 65% in five years, Zix is making headway. It tends to range in and out of the penny stock category, as it rises over $5 per share on occasion. As you might expect, the company is very small, with a market cap of just over $282 million. Revenues have been increasing steadily over the past four years. With earnings per share (EPS) in the positive column, this stock shows promise for investors who are willing to take on the risk of a penny stock. (For more, see: How to Invest in Penny Stocks.)

Glu Mobile Inc. (GLUU)

Glu Mobile makes games for smartphones. It has multiple titles that are gaining popularity for players who use phones or tablets. Many of the titles are based on action movies, while others are based on existing console games. Interestingly, its biggest selling game is casual role-playing game based on the life of reality TV star Kim Kardashian.

The company has worked its way out of debt and has strong cash reserves. Revenues have been rising over the past four quarters, but operating income is negative. Glu Mobile is spending on research and development to find its next hit. The potential for this stock is based on its industry. Games continue to grow in popularity, and gamers are willing to try new games, even if they are not from large companies. Glu Mobile could come up with a hit game that will send the stock soaring.

Arotech has positioned itself as a significant provider of surveillance and attack technologies at a time when drones are gaining increased attention and artificial intelligence is being deployed. Revenues have not grown in the past four quarters, and the company's operating income remains negative. That means investors who buy this stock are doing so based on the potential for both the company and the sector. (For more, see: Top 6 Drone Stocks.)

The Bottom Line

The trouble with penny stocks is that investors have to make some guesses about the future. Very few penny stocks have a strong enough track record to indicate that they will survive and prosper. That said, the penny stocks on our list operate in significant industries and have the potential to be vital players in those industries. (See also: The Lowdown on Penny Stocks.)
