Facebook (FB) is our newest recommendation; perhaps the most important number for the company is the nearly 1.9 billion people who use the service on a daily basis, explains Stephen Leeb, editor of The Complete Investor.

Monthly the number rises to over 2.85 billion. Nearly 98% of revenues come from advertising. By far the biggest chunk of advertising revenues – some 44% - comes from domestic sources, which account for less than 10% of monthly active users (MAUs).

A decade ago, domestic MAUs were over 25% of the total and represented over 58% of revenues. By a wide margin, the company’s largest user base is in the developing world.

For example, India has more than 330 million users. This leaves the company with tremendous growth opportunities in that the developing world, even excluding China, which does not use Facebook, is 10 times the size of the U.S.

Though developing countries spend much less per person, their much larger aggregate population still produces nearly comparable revenues with tremendous potential for growth both in users and in money spent per user.

Facebook is among the world’s leaders in artificial intelligence. For example, it was one of the first companies to develop algorithms for facial recognition.

It has been introducing products based on its AI expertise, including ones using virtual and augmented reality. These products come close to allowing users to experience everything from exercise instruction to concerts as if they were tin the room.

While revenues from these products are just a bit more than 2% of companywide revenue, they have been growing at a 50% rate. The company’s enormous user base is an opportunity to monetize burgeoning applications of AI.

We know that Facebook is controversial and could face legal challenges ahead, but its enormous and growing user base arguably gives it the greatest potential for sustainable rapid growth among the big-cap tech leaders.
