Elringklinger has a huge upside potential considering his only 1B market cap. We may see at least 30 Euro short term. Personally, I see a new ATH this year and maybe way above ATH. Germany is taking the hydrogen way. And not only Germany. The whole EU.
It's only my personal view. It's not an investment advice. But for the time being, after I got out of FCEL and PLUG, Elringklinger is by biggest asset.
