If you want to compound wealth in the stock market, you can do so by buying an index fund. But you can significantly boost your returns by picking above-average stocks. To wit, the Rotork plc (LON:ROR) share price is 22% higher than it was a year ago, much better than the market return of around 0.8% (not including dividends) in the same period. That's a solid performance by our standards! The longer term returns have not been as good, with the stock price only 3.5% higher than it was three years ago.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

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.

During the last year Rotork grew its earnings per share (EPS) by 40%. It's fair to say that the share price gain of 22% did not keep pace with the EPS growth. Therefore, it seems the market isn't as excited about Rotork as it was before. This could be an opportunity.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Rotork the TSR over the last 1 year was 25%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!



A Different Perspective

We're pleased to report that Rotork shareholders have received a total shareholder return of 25% over one year. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 3% 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.
