By buying an index fund, you can roughly match the market return with ease. But if you choose individual stocks with prowess, you can make superior returns. For example, the Stemmer Imaging AG (ETR:S9I) share price is up 49% in the last three years, clearly besting the market decline of around 11% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 6.0% in the last year , including dividends .

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Stemmer Imaging became profitable within the last three years. That would generally be considered a positive, so we'd expect the share price to be up.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Stemmer Imaging, it has a TSR of 67% for the last 3 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Stemmer Imaging shareholders are up 6.0% for the year (even including dividends). But that was short of the market average. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 0.8% endured over half a decade. It could well be that the business is stabilizing. 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.
