For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it completely lacks a track record of revenue and profit. 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.

In the age of tech-stock blue-sky investing, my choice may seem old fashioned; I still prefer profitable companies like Blackstone (NYSE:BX). Now, I'm not saying that the stock is necessarily undervalued today; but I can't shake an appreciation for the profitability of the business itself. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

Blackstone's Earnings Per Share Are Growing.

If a company can keep growing earnings per share (EPS) long enough, its share price will eventually follow. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Impressively, Blackstone has grown EPS by 34% 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.

I like to take a look at earnings before interest and (EBIT) tax margins, as well as revenue growth, to get another take on the quality of the company's growth. Not all of Blackstone's revenue this year is revenue from operations, so keep in mind the revenue and margin numbers I've used might not be the best representation of the underlying business. While we note Blackstone's EBIT margins were flat over the last year, revenue grew by a solid 497% to US$17b. That's a real positive.

While we live in the present moment at all times, there's no doubt in my mind that the future matters more than the past. So why not check this interactive chart depicting future EPS estimates, for Blackstone?

Are Blackstone Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$145b company like Blackstone. But we are reassured by the fact they have invested in the company. Notably, they have an enormous stake in the company, worth US$178m. I would find that kind of skin in the game quite encouraging, if I owned shares, since it would ensure that the leaders of the company would also experience my success, or failure, with the stock.

Should You Add Blackstone To Your Watchlist?

For growth investors like me, Blackstone's raw rate of earnings growth is a beacon in the night. Further, the high level of insider ownership impresses me, and suggests that I'm not the only one who appreciates the EPS growth. 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.

Although Blackstone certainly looks good to me, I would like it more if insiders were buying up shares. If you like to see insider buying, too, then this free list of growing companies that insiders are buying, could be exactly what you're looking for.
