yes. Becuase, just look at me. First post here and i hardly have much stock experience or economical insight. im joe schmoe who just bought a stock because it may one day make him rich, and so i took a small position for one in SOL. I know a few things but seriously, stock markets are about psychology anyway regardless how much you know or don't and its not nessecarily about what things are worth, but about being early enough to jump a bandwagon. Even simple people know buying low before a bubble can make someone quite wealthy, and asside of stocks that are really worth it often you can incomprehensibly earn more on a stock priced to the stars out of poppularity.
And whats changed in the poppular landscape? Wel joe Schmoe is back now buying shares the of the likes of TSLA and SCTY, or atleast watching at fortunes suddently being made there and getting more and more convinced that now is the time to jump on the train that will eventually fuel itself out of poppularity untill the whole thing explode's into nastyness probably, not that the gainers will care. Sunpower and first solar have rebounded quite a bit, to the massive gain of those who jumped in soon enough. the trend seems to be changing quick.
Many of these solar and alt energy stocks are quite known among Joe Schmoe and they used to be quite pricey because of this poppularity, besides having actual potential. Many Joe's lost money but earned some in the 4 to 5 years since and is waiting for the ideal moment to jump train. Arguably he might think, solar will have grown up a bit in those years.
Yes, there is no actual solid reason why i should declare that the new bubble is going to start just now. But if you have the aking feeling too, well then id say i never had this much akin since years.
