I have no answers. Everyone here is sanguine about the prospects of Tesla's stock price skyrocketing in the future to 10^3 and more. I cannot refute that. I am not an investment wizard by any stretch.
I see substantial differences between Tesla and companies mentioned above like Alphabet, Facebook, and Amazon. On the one hand all these companies are heavy tech companies without question. But Tesla is a manufacturer. Tesla has raw materials, work in process and finished goods inventories for its vehicles, Powerwall, and solar products. Tesla makes its profits by manufacturing. Alphabet and Facebook do not. Amazon carries a finished goods inventory, but is not on the hook for manufacturing to my knowledge.
Yes, there is a significant part of all of Tesla's products that are tech, and they are selling tech. But in the end, they are selling cars, battery storage systems, and solar panels.
When Tesla starts to be profitable consistently and having surplus cash to pay down debt or invest in expansion, will the markets view Tesla more like a manufacturer or a tech company like Alphabet? Or perhaps a hybrid?
My uninformed guess is that Tesla's stock will be valued much higher than traditional automobile manufacturers, but not as consistently as high as the major tech players out there.
And then, if Tesla ever has the cash to pay dividends, yield begins to creep into the equation.
Left unsaid is the future operations of Tesla. Is it possible that one day Tesla will split into two or more companies? Or perhaps Tesla sells off a large segment of its business?
We will have to revisit this topic in 15 years!
