Did You Participate In Any Of Cognex's (NASDAQ:CGNX) Incredible 420% Return?

In this article:

We think all investors should try to buy and hold high quality multi-year winners. While not every stock performs well, when investors win, they can win big. Don't believe it? Then look at the Cognex Corporation (NASDAQ:CGNX) share price. It's 395% higher than it was five years ago. And this is just one example of the epic gains achieved by some long term investors. Also pleasing for shareholders was the 27% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 15% in 90 days).

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, Cognex managed to grow its earnings per share at 11% a year. This EPS growth is slower than the share price growth of 38% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 75.98.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Cognex the TSR over the last 5 years was 420%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Cognex has rewarded shareholders with a total shareholder return of 51% in the last twelve months. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 39% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. It's always interesting to track share price performance over the longer term. But to understand Cognex better, we need to consider many other factors.
