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 currently lacks a track record of revenue and profit. Sometimes these stories can cloud the minds of investors, leading them to invest with their emotions rather than on the merit of good company fundamentals. Loss-making companies are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like EnerSys (NYSE:ENS). 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 EnerSys Growing?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. So it makes sense that experienced investors pay close attention to company EPS when undertaking investment research. Recognition must be given to the that EnerSys has grown EPS by 38% per year, over the last three years. Growth that fast may well be fleeting, but it should be more than enough to pique the interest of the wary stock pickers.

It's often helpful to take a look at earnings before interest and tax (EBIT) margins, as well as revenue growth, to get another take on the quality of the company's growth. EnerSys shareholders can take confidence from the fact that EBIT margins are up from 6.4% to 10%, and revenue is growing. Ticking those two boxes is a good sign of growth, in our book.

Are EnerSys 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. So it is good to see that EnerSys insiders have a significant amount of capital invested in the stock. As a matter of fact, their holding is valued at US$42m. That's a lot of money, and no small incentive to work hard. While their ownership only accounts for 1.0%, this is still a considerable amount at stake to encourage the business to maintain a strategy that will deliver value to shareholders.

Does EnerSys Deserve A Spot On Your Watchlist?

EnerSys' earnings per share growth have been climbing higher at an appreciable rate. That EPS growth certainly is attention grabbing, and the large insider ownership only serves to further stoke our interest. The hope is, of course, that the strong growth marks a fundamental improvement in the business economics. Based on the sum of its parts, we definitely think its worth watching EnerSys very closely. If you think EnerSys might suit your style as an investor, you could go straight to its annual report, or you could first check our discounted cash flow (DCF) valuation for the company.
