Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. Unfortunately, that's been the case for longer term Pennon Group Plc (LON:PNN) shareholders, since the share price is down 51% in the last three years, falling well short of the market return of around 15%.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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 the three years that the share price declined, Pennon Group's earnings per share (EPS) dropped significantly, falling to a loss. Extraordinary items contributed to this situation. Due to the loss, it's not easy to use EPS as a reliable guide to the business. However, we can say we'd expect to see a falling share price in this scenario.

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.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Pennon Group the TSR over the last 3 years was -43%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Pennon Group shareholders gained a total return of 5.8% during the year. But that return falls short of the market. On the bright side, that's still a gain, and it's actually better than the average return of 0.4% over half a decade This suggests the company might be improving over time. 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.
