This is only in the current low interest rate environment. Back in the day you kids probably don't remember, where interest rates weren't 0, you could make some serious returns from the cash you got from selling the shares short.

I'm not an investor, I'm out of work, wish I had money to gamble at the moment, but something tells me the smarter move would be creating some sentiment algorithm that invests like $500 every time a positive/electric car article comes out in a competitor. Say Toyota releases new electric car, invest $500 immediately in Toyota, Nissan, do the same, etc...

Because when the tide turns all that money will go into whichever competitors are still standing and have the best e-car portfolios. Best to diversify.

If you could time it right, sure shortsell, but that's a HUGE risk, this one not so much...again I'm NOT a financial guru, my negative bank account could prove that, but it's just a hunch I have, a similar one I had in 2013 about bitcoin and kick myself daily for every day.
