Varta is a big player with energy storage systems. The coming Solar boom will give them lots of income via their systems. They are helping retailers to get state or local funding.
From a TA viewpoint, daily just retraced back to the EMA 21 and attacking EMA 200; daily MACD bullish Cross will happen next days (!!!) thats a good comeback up fast with a 10% move to the 0,681 Fibo.
