For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it currently lacks a track record of revenue and profit. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Arista Networks (NYSE:ANET). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

How Quickly Is Arista Networks Increasing Earnings Per Share?

If a company can keep growing earnings per share (EPS) long enough, its share price should eventually follow. That means EPS growth is considered a real positive by most successful long-term investors. To the delight of shareholders, Arista Networks has achieved impressive annual EPS growth of 49%, compound, over the last three years. Growth that fast may well be fleeting, but it should be more than enough to pique the interest of the wary stock pickers.

It's often helpful to take a look at earnings before interest and tax (EBIT) margins, as well as revenue growth, to get another take on the quality of the company's growth. The good news is that Arista Networks is growing revenues, and EBIT margins improved by 5.1 percentage points to 41%, over the last year. Both of which are great metrics to check off for potential growth.

Are Arista Networks Insiders Aligned With All Shareholders?

Owing to the size of Arista Networks, we wouldn't expect insiders to hold a significant proportion of the company. But we do take comfort from the fact that they are investors in the company. Notably, they have an enviable stake in the company, worth US$22b. Coming in at 18% of the business, that holding gives insiders a lot of influence, and plenty of reason to generate value for shareholders. Looking very optimistic for investors.

Should You Add Arista Networks To Your Watchlist?

Arista Networks' earnings have taken off in quite an impressive fashion. That EPS growth certainly is attention grabbing, and the large insider ownership only serves to further stoke our interest. The hope is, of course, that the strong growth marks a fundamental improvement in the business economics. Based on the sum of its parts, we definitely think its worth watching Arista Networks very closely. Of course, identifying quality businesses is only half the battle; investors need to know whether the stock is undervalued.
