Yet the stock price never went below $250. I wonder how many other tech unicorns are on the verge of bankruptcy. https://www.cnbc.com/2018/11/25/elon-musk-tesla-had-single-digit-weeks-before-it-would-die.html
Tesla was close to having $0 (~$300M) operational cash last year. It doesn't mean close to being bankruptcy!! Stock price is often a balance of assets in balance sheet and future potential for the company to deliver profits. Having said that, yes tech stocks are over valued than what above adds up to.
Why would Elon Musk announce this?
Seriously. This is something you mention 20 years after the company succeeds not 6 months after immense worry that it'll fail.
