With EPS Growth And More, Power Integrations (NASDAQ:POWI) Is Interesting

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.

So if you're like me, you might be more interested in profitable, growing companies, like Power Integrations (NASDAQ:POWI). While that doesn't make the shares worth buying at any price, you can't deny that successful capitalism requires profit, eventually. Conversely, a loss-making company is yet to prove itself with profit, and eventually the sweet milk of external capital may run sour.

How Quickly Is Power Integrations Increasing Earnings Per Share?

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. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. I, for one, am blown away by the fact that Power Integrations has grown EPS by 40% per year, over the last three years. Growth that fast may well be fleeting, but like a lotus blooming from a murky pond, it sparks joy for the wary stock pickers.

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). The good news is that Power Integrations is growing revenues, and EBIT margins improved by 8.8 percentage points to 26%, over the last year. That's great to see, on both counts.

Are Power Integrations Insiders Aligned With All Shareholders?

It makes me feel more secure owning shares in a company if insiders also own shares, thusly more closely aligning our interests. As a result, I'm encouraged by the fact that insiders own Power Integrations shares worth a considerable sum. Given insiders own a small fortune of shares, currently valued at US$82m, they have plenty of motivation to push the business to succeed. This should keep them focused on creating long term value for shareholders.

Is Power Integrations Worth Keeping An Eye On?

Power Integrations's earnings per share have taken off like a rocket aimed right at the moon. That EPS growth certainly has my attention, and the large insider ownership only serves to further stoke my interest. The hope is, of course, that the strong growth marks a fundamental improvement in the business economics. So to my mind Power Integrations is worth putting on your watchlist; after all, shareholders do well when the market underestimates fast growing companies. Don't forget that there may still be risks. For instance, we've identified 2 warning signs for Power Integrations that you should be aware of.

Of course, you can do well (sometimes) buying stocks that are not growing earnings and do not have insiders buying shares. But as a growth investor I always like to check out companies that do have those features. You can access a free list of them here.
