Once China ban Tesla due to national security reasons, without access to China's yuuuge manufacturing capability and market, the price of this shittly over-hyped piece of shit will go down to where it belong, toilet level.
The reception of stock hype success of american company nowadays is to built and sell things in China, and telling bullshit hype to investors.
Just like Jobs, Musk is hype promoter (just like the Chinese fraud businessmen Jie Yueting, but obviously he is not so lucky since Chinese dont love hype that much so he is now hide in the hype-heaven american from his debt-collectors now).
American investors love to invest into hype and promote hype, with their FED inject another dozen of trillions fiat money into market, and with all the buy-back, you cannot really judge how good the company is by its stock price, you can only judge how hyped-up the company is by the its trading price instead.
So you should use P/H (Price/Hype) ratio instead of P/E ratio, in terms of P/H ratio, I believe Tesla is still a solid buy.
While BYD shares price now looks attractive.
