EDAP TMS (NASDAQ:EDAP shareholders incur further losses as stock declines 20% this week, taking three-year losses to 76%

EDAP TMS S.A. (NASDAQ:EDAP) shareholders should be happy to see the share price up 29% in the last month. But the last three years have seen a terrible decline. In that time the share price has melted like a snowball in the desert, down 76%. So we're relieved for long term holders to see a bit of uplift. The thing to think about is whether the business has really turned around.

Since EDAP TMS has shed US$17m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

Our free stock report includes 3 warning signs investors should be aware of before investing in EDAP TMS. Read for free now.

EDAP TMS isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. When a company doesn't make profits, we'd generally hope to see good revenue growth. 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.

Over three years, EDAP TMS grew revenue at 9.0% per year. That's a fairly respectable growth rate. So it seems unlikely the 21% share price drop (each year) is entirely about the revenue. It could be that the losses were much larger than expected. This is exactly why investors need to diversify - even when a loss making company grows revenue, it can fail to deliver for shareholders.
