So what Not only could Tesla benefit from potentially more favorable green energy policies under Joe Biden's presidential administration, but a vaccine for COVID-19 would likely help mitigate some of the risks of the company's factories shutting down again, as they did during peak business lockdowns earlier this year.

Now what Earlier this year, Tesla suspended its guidance for more than 500,000 vehicles in 2020 as factory shutdowns translated to significant uncertainty about how the year would play out.
