It's only natural that many investors, especially those who are new to the game, prefer to buy shares in 'sexy' stocks with a good story, even if those businesses lose money. 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 Monolithic Power Systems (NASDAQ:MPWR), 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. 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.

Monolithic Power Systems's Earnings Per Share Are 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). It's no surprise, then, that I like to invest in companies with EPS growth. I, for one, am blown away by the fact that Monolithic Power Systems has grown EPS by 37% 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). While we note Monolithic Power Systems's EBIT margins were flat over the last year, revenue grew by a solid 19% to US$595m. That's progress.

Are Monolithic Power Systems Insiders Aligned With All Shareholders?

Since Monolithic Power Systems has a market capitalization of US$5.4b, 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$378m. This suggests to me that leadership will be very mindful of shareholders' interests when making decisions!

Does Monolithic Power Systems Deserve A Spot On Your Watchlist?

Monolithic Power Systems's earnings have taken off like any random crypto-currency did, back in 2017. 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 yes, on this short analysis I do think it's worth considering Monolithic Power Systems for a spot on your watchlist.
