The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Federal Signal Corporation (NYSE:FSS) share price has soared 223% in the last half decade. Most would be very happy with that. In the last week shares have slid back 2.3%.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over half a decade, Federal Signal managed to grow its earnings per share at 13% a year. This EPS growth is slower than the share price growth of 26% 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. That's not necessarily surprising considering the five-year track record of earnings growth.

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 Federal Signal the TSR over the last 5 years was 237%, 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

We're pleased to report that Federal Signal shareholders have received a total shareholder return of 35% over one year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 28% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. If you would like to research Federal Signal in more detail then you might want to take a look at whether insiders have been buying or selling shares in the company.
