Couldn't agree more that the sentiment doesn't make sense given what they have actually done, all of their proof, all their products, patents etc. (disclaimer: I'm long TSLA)

I'm just relaying what I have heard and read. Tesla's history is far from perfect. I think the target of issue has been their various claims and promises on 'self-driving' and their autonomous vehicle programs. Also, some possible issues surrounding the acquisition/merger of SolarCity.

And while the shorts around Tesla aren't making much noise right now given all the momentum, it wasn't all that long ago that there were some loud short sellers alleging about various accounting frauds. Some quick 'internet research' here will dig up various allegations and statements from the 'haters'.

More common at issue is that many traditional auto analysts' existing equity valuation models for auto companies 'break' when you plug in the numbers for Tesla - making it impossible to come to a 'reasonable' valuation they are comfortable buying at (as these are people investing other people's money need to be able to point to something that justifies the purchase if it goes south).
