As Advanced Medical Solutions Group (LON:AMS) ascends 9.0% this past week, investors may now be noticing the company's five-year earnings growth

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But even the best stock picker will only win with some selections. At this point some shareholders may be questioning their investment in Advanced Medical Solutions Group plc (LON:AMS), since the last five years saw the share price fall 14%. But it's up 9.0% in the last week.

On a more encouraging note the company has added UK£49m to its market cap in just the last 7 days, so let's see if we can determine what's driven the five-year loss for shareholders.

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.

While the share price declined over five years, Advanced Medical Solutions Group actually managed to increase EPS by an average of 0.3% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

With EPS gaining and a declining share price, one would suggest the market is cooling on its view of the company. Having said that, if the EPS gains continue we'd expect the share price to improve, longer term.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

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. 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 -12%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 1.5% in the last year, Advanced Medical Solutions Group shareholders lost 7.6% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% over the last half decade. 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.
