You are investing in this company and you have not even heard of one of its main competitors? Did you do any research before buying this stock? No wonder you think SCTY is so great, you apparently do not realize that there are other companies doing the exact same thing.
It doesn't matter if solar city's competition is a 1978 firm, Solar city's business model is really strong and efficient. You have to trust Lyndon Rive and Elon Musk with their entrepreneurial skills, at least Goldman Sachs does. The company is valued way above its fundamental value because investors and fund managers with a vision believe in its future and they probably believe that in the long run, the value of this stock would be much more worthy than it is now. Just stick around and hold it for the long term and trust me you will benefit from it.
You have to blindly trust Rive and Musk? What is this, a stock or a religion?
This stock is priced way above its fundamental value because a bunch of retail investors have bought into the hype and driven up a low float stock. Aside from the venture funds that have been locked up until Tuesday, there are virtually no institutional investors in this stock. Once those venture funds can sell, it will be ugly.
