The main aim of stock picking is to find the market-beating stocks. But even the best stock picker will only win with some selections. So we wouldn't blame long term Advanced Medical Solutions Group plc (LON:AMS) shareholders for doubting their decision to hold, with the stock down 34% over a half decade.

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.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 five years over which the share price declined, Advanced Medical Solutions Group's earnings per share (EPS) dropped by 0.3% each year. Readers should note that the share price has fallen faster than the EPS, at a rate of 8% per year, over the period. So it seems the market was too confident about the business, in the past.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Advanced Medical Solutions Group's TSR for the last 5 years was -32%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 3.7% in the last year, Advanced Medical Solutions Group shareholders lost 19% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 6% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround.
