TLDR research teams at nearly all the big Wall St banks wrote bullish reports on SpaceX and recommended buying it, some with very optimistic projections. The author says you can't always trust these reports because these banks also have a financial incentive to sell management services. Also covers how there is existing government regulation by Spitzer from 2003 dealing with this situation, where research teams are kept independent of the sales side but implies that doesn't eliminate financial incentives entirely, but also claims the regulation is still well enforced within banks. Other Wall St investment firms allegedly don't rely on these reports heavily and do their own research before investing.

Nothing too deep here.
