Investors in Mitsubishi Materials (TSE:5711) have unfortunately lost 23% over the last year

Investors can approximate the average market return by buying an index fund. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. For example, the Mitsubishi Materials Corporation (TSE:5711) share price is down 26% in the last year. That's disappointing when you consider the market returned 4.3%. On the other hand, the stock is actually up 19% over three years.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the unfortunate twelve months during which the Mitsubishi Materials share price fell, it actually saw its earnings per share (EPS) improve by 24%. It could be that the share price was previously over-hyped.

It's surprising to see the share price fall so much, despite the improved EPS. But we might find some different metrics explain the share price movements better.

We don't see any weakness in the Mitsubishi Materials' dividend so the steady payout can't really explain the share price drop. From what we can see, revenue is pretty flat, so that doesn't really explain the share price drop. Unless, of course, the market was expecting a revenue uptick.

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. As it happens, Mitsubishi Materials' TSR for the last 1 year was -23%, 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

Mitsubishi Materials shareholders are down 23% for the year (even including dividends), but the market itself is up 4.3%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 3%, each year, over five years. 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. Like risks, for instance. Every company has them, and we've spotted 2 warning signs for Mitsubishi Materials (of which 1 makes us a bit uncomfortable!) you should know about.
