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. A loss-making company is yet to prove itself with profit, and eventually the inflow of external capital may dry up.

If this kind of company isn't your style, you like companies that generate revenue, and even earn profits, then you may well be interested in ResMed (NYSE:RMD). 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 ResMed 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. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Shareholders will be happy to know that ResMed's EPS has grown 29% each year, compound, over three years. As a general rule, we'd say that if a company can keep up that sort of growth, shareholders will be beaming.

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. ResMed shareholders can take confidence from the fact that EBIT margins are up from 27% to 30%, and revenue is growing. Both of which are great metrics to check off for potential growth.

Are ResMed Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$36b company like ResMed. 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$279m. We note that this amounts to 0.8% of the company, which may be small owing to the sheer size of ResMed but it's still worth mentioning. This should still be a great incentive for management to maximise shareholder value.

Does ResMed Deserve A Spot On Your Watchlist?

For growth investors, ResMed'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. Fast growth and confident insiders should be enough to warrant further research, so it would seem that it's a good stock to follow. Still, you should learn about the 1 warning sign we've spotted with ResMed.

While opting for stocks without growing earnings and absent insider buying can yield results, for investors valuing these key metrics, here is a carefully selected list of companies in the US with promising growth potential and insider confidence.
