When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. Long term Photronics, Inc. (NASDAQ:PLAB) shareholders would be well aware of this, since the stock is up 218% in five years. On top of that, the share price is up 46% in about a quarter.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

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 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.

During five years of share price growth, Photronics achieved compound earnings per share (EPS) growth of 27% per year. This EPS growth is remarkably close to the 26% average annual increase in the share price. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

It's nice to see that Photronics shareholders have received a total shareholder return of 81% over the last year. That's better than the annualised return of 26% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. Is Photronics cheap compared to other companies?
