Some have more dollars than sense, they say, so even companies that have no revenue, no profit, and a record of falling short, can easily find investors. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.'

In contrast to all that, I prefer to spend time on companies like Apple (NASDAQ:AAPL), which has not only revenues, but also profits. Even if the shares are fully valued today, most capitalists would recognize its profits as the demonstration of steady value generation. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

How Quickly Is Apple Increasing Earnings Per Share?

As one of my mentors once told me, share price follows earnings per share (EPS). That means EPS growth is considered a real positive by most successful long-term investors. Impressively, Apple has grown EPS by 20% per year, compound, in the last three years. As a general rule, we'd say that if a company can keep up that sort of growth, shareholders will be smiling.

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. Apple shareholders can take confidence from the fact that EBIT margins are up from 24% to 27%, and revenue is growing. That's great to see, on both counts.

In the chart below, you can see how the company has grown earnings, and revenue, over time. To see the actual numbers, click on the chart.

Are Apple Insiders Aligned With All Shareholders?

Since Apple has a market capitalization of US$2.2t, we wouldn't expect insiders to hold a large percentage of shares. But we are reassured by the fact they have invested in the company. Indeed, they have a glittering mountain of wealth invested in it, currently valued at US$1.3b. This suggests to me that leadership will be very mindful of shareholders' interests when making decisions!

Does Apple Deserve A Spot On Your Watchlist?

Given my belief that share price follows earnings per share you can easily imagine how I feel about Apple's strong EPS growth. I think that EPS growth is something to boast of, and it doesn't surprise me that insiders are holding on to a considerable chunk of shares. Fast growth and confident insiders should be enough to warrant further research. So the answer is that I do think this is a good stock to follow along with. However, before you get too excited we've discovered 1 warning sign for Apple that you should be aware of.
