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.

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 eBay (NASDAQ:EBAY). Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.

How Quickly Is eBay Increasing Earnings Per Share?

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 means EPS growth is considered a real positive by most successful long-term investors. It certainly is nice to see that eBay has managed to grow EPS by 19% per year over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.

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. While we note eBay achieved similar EBIT margins to last year, revenue grew by a solid 2.5% to US$10b. That's a real positive.

Are eBay Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$31b company like eBay. 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$101m. This comes in at 0.3% of shares in the company, which is a fair amount of a business of this size. So despite their percentage holding being low, company management still have plenty of reasons to deliver the best outcomes for investors.

Should You Add eBay To Your Watchlist?

You can't deny that eBay has grown its earnings per share at a very impressive rate. That's attractive. This EPS growth rate is something the company should be proud of, and so it's no surprise that insiders are holding on to a considerable chunk of shares. 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. It is worth noting though that we have found 4 warning signs for eBay (1 is potentially serious!) that you need to take into consideration.

There's always the possibility of doing well buying stocks that are not growing earnings and do not have insiders buying shares.
