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. And in their study titled Who Falls Prey to the Wolf of Wall Street?' Leuz et. al. found that it is 'quite common' for investors to lose money by buying into 'pump and dump' schemes.

In contrast to all that, I prefer to spend time on companies like BOK Financial (NASDAQ:BOKF), 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 Fast Is BOK Financial Growing?

The market is a voting machine in the short term, but a weighing machine in the long term, so share price follows earnings per share (EPS) eventually. It's no surprise, then, that I like to invest in companies with EPS growth. Over the last three years, BOK Financial has grown EPS by 15% per year. That growth rate is fairly good, assuming the company can keep it up.

I like to see top-line growth as an indication that growth is sustainable, and I look for a high earnings before interest and taxation (EBIT) margin to point to a competitive moat (though some companies with low margins also have moats). Not all of BOK Financial'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 BOK Financial's EBIT margins were flat over the last year, revenue grew by a solid 24% to US$2.0b. That's a real positive.

Are BOK Financial Insiders Aligned With All Shareholders?

Personally, I like to see high insider ownership of a company, since it suggests that it will be managed in the interests of shareholders. So we're pleased to report that BOK Financial insiders own a meaningful share of the business. Indeed, with a collective holding of 57%, company insiders are in control and have plenty of capital behind the venture. This makes me think they will be incentivised to plan for the long term - something I like to see. And their holding is extremely valuable at the current share price, totalling US$3.5b. Now that's what I call some serious skin in the game!
