The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of Signet Jewelers Limited (NYSE:SIG) stock is up an impressive 285% over the last five years. It's also good to see the share price up 41% over the last quarter.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

During the last half decade, Signet Jewelers became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Signet Jewelers, it has a TSR of 327% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Signet Jewelers shareholders have received a total shareholder return of 29% over one year. And that does include the dividend. However, that falls short of the 34% TSR per annum it has made for shareholders, each year, over five years.
