Solar power is «in»! The only pure solar energy play on SIX is Edisun Power. The stock has been traded since 2008, at which point it was the one of the few listed solar power companies still trading in Europe. And although Edisun shares rose steeply in the five years up to 2019, they have predominantly trended sideways since then. In 2022 the company announced an opportunistic change in strategy, which should give a further boost to earnings development.
