Stock pickers are generally looking for stocks that will outperform the broader market. Buying under-rated businesses is one path to excess returns. For example, long term Aristocrat Leisure Limited (ASX:ALL) shareholders have enjoyed a 67% share price rise over the last half decade, well in excess of the market return of around 22% (not including dividends).

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.

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 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 five years of share price growth, Aristocrat Leisure achieved compound earnings per share (EPS) growth of 17% per year. This EPS growth is higher than the 11% average annual increase in the share price. Therefore, it seems the market has become relatively pessimistic about the company.

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 Aristocrat Leisure the TSR over the last 5 years was 79%, 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 regret to report that Aristocrat Leisure shareholders are down 23% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 1.9%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 12% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
