Buying a low-cost index fund will get you the average market return. But across the board there are plenty of stocks that underperform the market. That's what has happened with the bioMérieux S.A. (EPA:BIM) share price. It's up 12% over three years, but that is below the market return. Looking at more recent returns, the stock is up 7.1% in a year.

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 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. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the three years of share price growth, bioMérieux actually saw its earnings per share (EPS) drop 12% per year.

Earnings per share have melted like a stack of ice cubes, in stark contrast to the share price. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

Languishing at just 0.8%, we doubt the dividend is doing much to prop up the share price. It could be that the revenue growth of 5.4% per year is viewed as evidence that bioMérieux is growing. If the company is being managed for the long term good, today's shareholders might be right to hold on.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, bioMérieux'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

bioMérieux shareholders are up 7.9% for the year (even including dividends). But that return falls short of the market. But at least that's still a gain! Over five years the TSR has been a reduction of 0.8% per year, over five years. So this might be a sign the business has turned its fortunes around. It's always interesting to track share price performance over the longer term. But to understand bioMérieux better, we need to consider many other factors.
