What you are describing is not an investment strategy, at the end it sounds like a pyramid scheme.
In the investing world they call it a bubble.
... while telling the greater fools that it’s because of Tesla’s superior self-driving capabilities and battery tech.
Stock prices have apparently nothing to do with company earnings and performance so how do you know Tesla isn't worth 2000/3000/4000$ per stock?
Investors buy Tesla because they hope a lot of others will too in the future. As long as this hope is there and more people put their money into Tesla, the stock price will continue to rise.
