Here's Why We Think Power Integrations (NASDAQ:POWI) Is Well Worth Watching

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. But as Warren Buffett has mused, 'If you've been playing poker for half an hour and you still don't know who the patsy is, you're the patsy.' When they buy such story stocks, investors are all too often the patsy.

In contrast to all that, I prefer to spend time on companies like Power Integrations (NASDAQ:POWI), which has not only revenues, but also profits. 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. While a well funded company may sustain losses for years, unless its owners have an endless appetite for subsidizing the customer, it will need to generate a profit eventually, or else breathe its last breath.

How Fast Is Power Integrations Growing?

As one of my mentors once told me, share price follows earnings per share (EPS). Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. As a tree reaches steadily for the sky, Power Integrations's EPS has grown 33% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away winners.

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 Power Integrations is growing revenues, and EBIT margins improved by 10.5 percentage points to 25%, over the last year. That's great to see, on both counts.

Are Power Integrations Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$5.1b company like Power Integrations. But we do take comfort from the fact that they are investors in the company. Given insiders own a small fortune of shares, currently valued at US$89m, they have plenty of motivation to push the business to succeed. This should keep them focused on creating long term value for shareholders.

It's good to see that insiders are invested in the company, but are remuneration levels reasonable? A brief analysis of the CEO compensation suggests they are. I discovered that the median total compensation for the CEOs of companies like Power Integrations with market caps between US$4.0b and US$12b is about US$6.4m.

Power Integrations offered total compensation worth US$5.7m to its CEO in the year to . That seems pretty reasonable, especially given its below the median for similar sized companies. CEO remuneration levels are not the most important metric for investors, but when the pay is modest, that does support enhanced alignment between the CEO and the ordinary shareholders. I'd also argue reasonable pay levels attest to good decision making more generally.

Does Power Integrations Deserve A Spot On Your Watchlist?

For growth investors like me, Power Integrations's raw rate of earnings growth is a beacon in the night. If you need more convincing beyond that EPS growth rate, don't forget about the reasonable remuneration and the high insider ownership. This may only be a fast rundown, but the takeaway for me is that Power Integrations is worth keeping an eye on.
