It's common for many investors, especially those who are inexperienced, to buy shares in companies with a good story even if these companies are loss-making. 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 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 Fast Is Eaton 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 makes EPS growth an attractive quality for any company. Shareholders will be happy to know that Eaton's EPS has grown 23% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away satisfied.

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 do take comfort from the fact that they are investors in the company. Notably, they have an enviable stake in the company, worth US$259m. 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 still shows shareholders there is a degree of alignment between management and themselves.
