I found this Anonymous post under that article:
"analysts are about the most short-sighted people on the planet. they look at how this will impact earnings in 1 or 2 quarters from now, but dont look beyond that to the future. this autonomous driving demonstration is nothing short of the proof that tesla will be a monster of a company in 5 years from now. who is in the lead on the coming transportation automation revolution - tesla. who does get it? wall street's analysts. i remember buying tesla at 30 when the analysts were trashing it. wish i had bought more. this time i will load up over the coming months."
In my view, analysts like Brian Johnson probably is not THAT short-sighted. They are twisting things for personal agenda.
In this case, who will buy a model S/X without advanced autopilot? who will buy the car without autonomous? Sure there may be a few exceptions, it's going to be very rare.
This is a clear case that Tesla's margin will improve going forward (assume other factors remain constant), this analyst twisted it into a reduced margin.
Also, Brian Johnson suggests investors to make a pair trade: short Tesla and long MBLY. I wouldn't be surprised to see MBLY to get a cat bounce, because there are so many manipulators looking at the charts. However, this is like after seeing Apple introduced iPhone, suggesting investors to short AAPL and long Nokia.
