Should You Be Adding Diodes (NASDAQ:DIOD) To Your Watchlist Today?

Simply Wall St

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 Diodes (NASDAQ:DIOD), which has not only revenues, but also profits. 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 Fast Is Diodes Growing Its Earnings Per Share?

In business, though not in life, profits are a key measure of success; and share prices tend to reflect earnings per share (EPS). So like the hint of a smile on a face that I love, growing EPS generally makes me look twice. It is therefore awe-striking that Diodes's EPS went from US$0.32 to US$2.34 in just one year. Even though that growth rate is unlikely to be repeated, that looks like a breakout improvement.

I like to take a look at earnings before interest and (EBIT) tax margins, as well as revenue growth, to get another take on the quality of the company's growth. The good news is that Diodes is growing revenues, and EBIT margins improved by 3.7 percentage points to 14%, over the last year. That's great to see, on both counts.

Are Diodes Insiders Aligned With All Shareholders?

I like company leaders to have some skin in the game, so to speak, because it increases alignment of incentives between the people running the business, and its true owners. As a result, I'm encouraged by the fact that insiders own Diodes shares worth a considerable sum. Given insiders own a small fortune of shares, currently valued at US$78m, they have plenty of motivation to push the business to succeed. This should keep them focused on creating long term value for shareholders.

Is Diodes Worth Keeping An Eye On?

Diodes's earnings per share have taken off like a rocket aimed right at the moon. That sort of growth is nothing short of eye-catching, and the large investment held by insiders certainly brightens my view of the company. 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 Diodes for a spot on your watchlist. Of course, just because Diodes is growing does not mean it is undervalued.

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.
