Listen to the news

Dynavax Technologies (DVAX) has quietly turned in a strong run, with the stock up about 41% over the past month and 52% in the past 3 months, inviting a closer look.

See our latest analysis for Dynavax Technologies.

Zooming out, that powerful 3 month share price return sits alongside a 5 year total shareholder return above 200%. This suggests the latest move looks more like renewed momentum than a one off spike at the current $15.38 share price.

If Dynavax’s run has you rethinking your healthcare exposure, it might be a good time to explore other vaccine makers and biotech names in healthcare stocks.
