Should You Be Adding Teradyne (NASDAQ:TER) To Your Watchlist Today?

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.

So if you're like me, you might be more interested in profitable, growing companies, like Teradyne (NASDAQ:TER). While profit is not necessarily a social good, it's easy to admire a business that can consistently produce it. In comparison, loss making companies act like a sponge for capital - but unlike such a sponge they do not always produce something when squeezed.

How Fast Is Teradyne Growing Its Earnings Per Share?

In the last three years Teradyne's earnings per share took off like a rocket; fast, and from a low base. So the actual rate of growth doesn't tell us much. As a result, I'll zoom in on growth over the last year, instead. Like a falcon taking flight, Teradyne's EPS soared from US$4.31 to US$6.05, over the last year. That's a impressive gain of 40%.

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. Teradyne shareholders can take confidence from the fact that EBIT margins are up from 28% to 32%, and revenue is growing. Ticking those two boxes is a good sign of growth, in my book.

Are Teradyne Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$26b company like Teradyne. But we are reassured by the fact they have invested in the company. To be specific, they have US$47m worth of shares. That shows significant buy-in, and may indicate conviction in the business strategy. Even though that's only about 0.2% of the company, it's enough money to indicate alignment between the leaders of the business and ordinary shareholders.

Does Teradyne Deserve A Spot On Your Watchlist?

Given my belief that share price follows earnings per share you can easily imagine how I feel about Teradyne's strong EPS growth. Further, the high level of insider ownership impresses me, and suggests that I'm not the only one who appreciates the EPS growth. So this is very likely the kind of business that I like to spend time researching, with a view to discerning its true value. What about risks?
