Shorting probably works best for established companies that are sinking... blockbuster for example... trend is clear, risk is low...
with Tesla on the other hand, who knows how it will play out? for all we know some Tesla related good news will come out this year, and their stock price could triple = you are fucked if you shorted...
plus shorting startup companies that are creating cool innovative products kinda has a bad vibe to it... just imagine 10 years from now, everyone could be bragging how they invested in Tesla early on and made a fortune... while you were the idiot who was shorting it...
