The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. Long term Cognex Corporation (NASDAQ:CGNX) shareholders would be well aware of this, since the stock is up 296% in five years. It's also up 8.6% in about a month. But this could be related to good market conditions -- stocks in its market are up 3.7% in the last month.
In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.
Over half a decade, Cognex managed to grow its earnings per share at 17% a year. This EPS growth is slower than the share price growth of 32% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth. This optimism is visible in its fairly high P/E ratio of 65.43.
The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).
We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years. It might be well worthwhile taking a look at our free report on Cognex's earnings, revenue and cash flow.
What About Dividends?
It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Cognex the TSR over the last 5 years was 315%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.
A Different Perspective
Cognex provided a TSR of 44% over the year (including dividends). That's fairly close to the broader market return. That gain looks pretty satisfying, and it is even better than the five-year TSR of 33% per year. It is possible that management foresight will bring growth well into the future, even if the share price slows down. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Take risks, for example - Cognex has 1 warning sign we think you should be aware of.
