The article doesn’t mention (or I’ve missed it) the short squeeze aspect which is definitely one of the drivers. https://investorplace.com/2020/01/play-tesla-stock-short-squ...
It's that "opportunities to own the stock in the future part" that got me. People just want to own the stock. Tesla has gotten big enough so it is pretty unlikely to fail. Customers love the product, there are several "it is the future" features. People want to own a part of that. I don't think many people are selling because of that. Even if it is really expensive right now.
