I remember the time roughly 3 1/2 years ago when I was heavily invested in hydrogen stocks before the great hype.
There was always the "battle" between Ballard Power and Plug Power. Ballard Power was always much more expensive in terms of revenue multiples compared to Plug. I never understood why this was the case back then. Plug was simply the better deal in my eyes.
Well, at some point in time Plug was set free, began to rise massively and Ballard was the stock being left behind.....for good reasons. After having held Plug for roughly 1 3/4 years, I sold them all as 15-bagger.
It's highly likely in my eyes that history will repeat in this case here
