Dynavax Technologies (NASDAQ:DVAX) shareholders are still up 187% over 5 years despite pulling back 3.9% in the past week

When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, you can make far more than 100% on a really good stock. For example, the Dynavax Technologies Corporation (NASDAQ:DVAX) share price has soared 187% in the last half decade. Most would be very happy with that. On the other hand, the stock price has retraced 3.9% in the last week. This could be related to the recent financial results, released recently -- you can catch up on the most recent data by reading our company report.

While the stock has fallen 3.9% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

On the bright side, long term shareholders have made money, with a gain of 23% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend.
