Do Afya's (NASDAQ:AFYA) Earnings Warrant Your Attention?

Investors are often guided by the idea of discovering 'the next big thing', even if that means buying 'story stocks' without any revenue, let alone profit. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Afya (NASDAQ:AFYA). Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.

How Fast Is Afya Growing?

The market is a voting machine in the short term, but a weighing machine in the long term, so you'd expect share price to follow earnings per share (EPS) outcomes eventually. That means EPS growth is considered a real positive by most successful long-term investors. It certainly is nice to see that Afya has managed to grow EPS by 18% per year over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.
