As an investor its worth striving to ensure your overall portfolio beats the market average. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term Metcash Limited (ASX:MTS) shareholders, since the share price is down 27% in the last three years, falling well short of the market return of around 27%.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the three years that the share price fell, Metcash's earnings per share (EPS) dropped by 0.8% each year. The share price decline of 10% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Metcash's TSR for the last 3 years was -14%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market gained around 8.5% in the last year, Metcash shareholders lost 15% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 9%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
