Like a puppy chasing its tail, some new investors often chase 'the next big thing', even if that means buying 'story stocks' without revenue, let alone profit. Unfortunately, high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson.

If, on the other hand, you like companies that have revenue, and even earn profits, then you may well be interested in Mimecast (NASDAQ:MIME). 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. Loss-making companies are always racing against time to reach financial sustainability, but time is often a friend of the profitable company, especially if it is growing.

How Fast Is Mimecast Growing Its Earnings Per Share?

Over the last three years, Mimecast has grown earnings per share (EPS) like young bamboo after rain; fast, and from a low base. So I don't think the percent growth rate is particularly meaningful. Thus, it makes sense to focus on more recent growth rates, instead. Like the last firework on New Year's Eve accelerating into the sky, Mimecast's EPS shot from US$0.42 to US$0.71, over the last year. You don't see 69% year-on-year growth like that, very often.

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. Mimecast shareholders can take confidence from the fact that EBIT margins are up from 6.1% to 11%, and revenue is growing. Ticking those two boxes is a good sign of growth, in my book.

Of course the knack is to find stocks that have their best days in the future, not in the past. You could base your opinion on past performance, of course, but you may also want to check this interactive graph of professional analyst EPS forecasts for Mimecast.

Are Mimecast Insiders Aligned With All Shareholders?

Since Mimecast has a market capitalization of US$5.3b, we wouldn't expect insiders to hold a large percentage of shares. But we do take comfort from the fact that they are investors in the company. Indeed, they have a glittering mountain of wealth invested in it, currently valued at US$327m. This suggests to me that leadership will be very mindful of shareholders' interests when making decisions!
