It's common for many investors, especially those who are inexperienced, to buy shares in companies with a good story even if these companies are loss-making. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Nextracker (NASDAQ:NXT). 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 Nextracker Growing Its Earnings Per Share?

Even modest earnings per share growth (EPS) can create meaningful value, when it is sustained reliably from year to year. So it's no surprise that some investors are more inclined to invest in profitable businesses. Commendations have to be given in seeing that Nextracker grew its EPS from US$0.025 to US$2.24, in one short year. While it's difficult to sustain growth at that level, it bodes well for the company's outlook for the future. This could point to the business hitting a point of inflection.

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 good news is that Nextracker is growing revenues, and EBIT margins improved by 14.5 percentage points to 23%, over the last year. That's great to see, on both counts.

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 Nextracker.

Are Nextracker Insiders Aligned With All Shareholders?

Since Nextracker has a market capitalisation of US$6.8b, we wouldn't expect insiders to hold a large percentage of shares. But we are reassured by the fact they have invested in the company. To be specific, they have US$18m worth of shares. That's a lot of money, and no small incentive to work hard. While their ownership only accounts for 0.3%, this is still a considerable amount at stake to encourage the business to maintain a strategy that will deliver value to shareholders.

Does Nextracker Deserve A Spot On Your Watchlist?

Nextracker's earnings per share have been soaring, with growth rates sky high. This level of EPS growth does wonders for attracting investment, and the large insider investment in the company is just the cherry on top. The hope is, of course, that the strong growth marks a fundamental improvement in the business economics. So at the surface level, Nextracker is worth putting on your watchlist; after all, shareholders do well when the market underestimates fast growing companies. Of course, identifying quality businesses is only half the battle; investors need to know whether the stock is undervalued.

There's always the possibility of doing well buying stocks that are not growing earnings and do not have insiders buying shares.
