The excitement of investing in a company that can reverse its fortunes is a big draw for some speculators, so even companies that have no revenue, no profit, and a record of falling short, can manage to find investors. 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 are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Eaton (NYSE:ETN). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

How Quickly Is Eaton Increasing Earnings Per Share?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. That makes EPS growth an attractive quality for any company. Shareholders will be happy to know that Eaton's EPS has grown 33% each year, compound, over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.

One way to double-check a company's growth is to look at how its revenue, and earnings before interest and tax (EBIT) margins are changing. The good news is that Eaton is growing revenues, and EBIT margins improved by 2.6 percentage points to 17%, over the last year. That's great to see, on both counts.

Are Eaton Insiders Aligned With All Shareholders?

Owing to the size of Eaton, we wouldn't expect insiders to hold a significant proportion of the company. But we are reassured by the fact they have invested in the company. Indeed, they have a considerable amount of wealth invested in it, currently valued at US$318m. While that is a lot of skin in the game, we note this holding only totals to 0.2% of the business, which is a result of the company being so large. This should still be a great incentive for management to maximise shareholder value.

Does Eaton Deserve A Spot On Your Watchlist?

For growth investors, Eaton's raw rate of earnings growth is a beacon in the night. With EPS growth rates like that, it's hardly surprising to see company higher-ups place confidence in the company through continuing to hold a significant investment. The growth and insider confidence is looked upon well and so it's worthwhile to investigate further with a view to discern the stock's true value. Still, you should learn about the 1 warning sign we've spotted with Eaton.
