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.

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 Dover (NYSE:DOV). Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Dover with the means to add long-term value to shareholders.

How Quickly Is Dover 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 means EPS growth is considered a real positive by most successful long-term investors. Impressively, Dover has grown EPS by 24% per year, compound, in the last 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. EBIT margins for Dover remained fairly unchanged over the last year, however the company should be pleased to report its revenue growth for the period of 11% to US$8.2b. That's a real positive.

Are Dover Insiders Aligned With All Shareholders?

Since Dover has a market capitalisation of US$16b, we wouldn't expect insiders to hold a large percentage of shares. But thanks to their investment in the company, it's pleasing to see that there are still incentives to align their actions with the shareholders. Given insiders own a significant chunk of shares, currently valued at US$73m, they have plenty of motivation to push the business to succeed. This would indicate that the goals of shareholders and management are one and the same.

Does Dover Deserve A Spot On Your Watchlist?

For growth investors, Dover's raw rate of earnings growth is a beacon in the night. Further, the high level of insider ownership is impressive and suggests that the management appreciates the EPS growth and has faith in Dover's continuing strength. On the balance of its merits, solid EPS growth and company insiders who are aligned with the shareholders would indicate a business that is worthy of further research. However, before you get too excited we've discovered 1 warning sign for Dover that you should be aware of.
