I have a love/hate relationship with Adam Jonas
I think he provides the deepest analyst research/coverage of tesla over the years
However, AJ sometimes he gets into "pissing contests" with Elon. One example was Jonas asking about an Uber-like ride sharing service on EC. Elon didn't want to take about it. Jonas brought it up in subsequent ECs. Finally, Elon revealed it as part of the Secret Master Plan 2 Adam clearly has a very big ego.
As we know, For better or worse Morgan Stanley and Goldman Sachs move Tesla more than any other analyst
I don't believe in the Chinese Wall between Research side and Investment Bank side. There have been some epic violations especially GS around the cap raises
Finally, I clearly cynically believe analysts are paid to support their houses agenda regardless of their personal belief in the stocks they are covering.
