If you love investing in stocks you're bound to buy some losers. But the long term shareholders of EDAP TMS S.A. (NASDAQ:EDAP) have had an unfortunate run in the last three years. So they might be feeling emotional about the 68% share price collapse, in that time. And over the last year the share price fell 66%, so we doubt many shareholders are delighted. Shareholders have had an even rougher run lately, with the share price down 23% in the last 90 days.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

EDAP TMS wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

In the last three years, EDAP TMS saw its revenue grow by 12% per year, compound. That's a fairly respectable growth rate. So some shareholders would be frustrated with the compound loss of 19% per year. The market must have had really high expectations to be disappointed with this progress. It would be well worth taking a closer look at the company, to determine growth trends (and balance sheet strength).

A Different Perspective

While the broader market gained around 26% in the last year, EDAP TMS shareholders lost 66%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 7% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
