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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. 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 N-able (NYSE:NABL). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

How Fast Is N-able Growing Its Earnings Per Share?

In the last three years N-able's earnings per share took off; so much so that it's a bit disingenuous to use these figures to try and deduce long term estimates. As a result, we'll zoom in on growth over the last year, instead. Impressively, N-able's EPS catapulted from US$0.066 to US$0.12, over the last year. It's not often a company can achieve year-on-year growth of 76%.

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. The music to the ears of N-able shareholders is that EBIT margins have grown from 12% to 16% in the last 12 months and revenues are on an upwards trend as well. That's great to see, on both counts.

Are N-able Insiders Aligned With All Shareholders?

It should give investors a sense of security owning shares in a company if insiders also own shares, creating a close alignment their interests. Shareholders will be pleased by the fact that insiders own N-able shares worth a considerable sum. Indeed, they hold US$21m worth of its stock. That shows significant buy-in, and may indicate conviction in the business strategy. While their ownership only accounts for 0.9%, this is still a considerable amount at stake to encourage the business to maintain a strategy that will deliver value to shareholders.

Should You Add N-able To Your Watchlist?

N-able's earnings have taken off in quite an impressive fashion. This level of EPS growth does wonders for attracting investment, and the large insider investment in the company is just the cherry on top. At times fast EPS growth is a sign the business has reached an inflection point, so there's a potential opportunity to be had here. So at the surface level, N-able is worth putting on your watchlist; after all, shareholders do well when the market underestimates fast growing companies. One of Buffett's considerations when discussing businesses is if they are capital light or capital intensive. Generally, a company with a high return on equity is capital light, and can thus fund growth more easily. So you might want to check this graph comparing N-able's ROE with industry peers (and the market at large).

Although N-able certainly looks good, it may appeal to more investors if insiders were buying up shares. If you like to see companies with insider buying, then check out this handpicked selection of companies that not only boast of strong growth but have also seen recent insider buying..
