Did Changing Sentiment Drive DBV Technologies's (EPA:DBV) Share Price Down A Painful 81%?

It's not possible to invest over long periods without making some bad investments. But you want to avoid the really big losses like the plague. So take a moment to sympathize with the long term shareholders of DBV Technologies S.A. (EPA:DBV), who have seen the share price tank a massive 81% over a three year period. That would be a disturbing experience. And the ride hasn't got any smoother in recent times over the last year, with the price 61% lower in that time. Furthermore, it's down 33% in about a quarter. That's not much fun for holders.

We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

DBV Technologies isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

Over three years, DBV Technologies grew revenue at 14% per year. That's a fairly respectable growth rate. So it seems unlikely the 42% share price drop (each year) is entirely about the revenue. More likely, the market was spooked by the cost of that revenue. If you buy into companies that lose money then you always risk losing money yourself. Just don't lose the lesson.
