Each broker had their own self serving purpose, ie are they shorting the stock? Did they not get preferential treatment from the company for different issues, promotional events, share allocations, whatever.
Remember brokers make money on churn and fees.
Call me skeptical but I remember a few years ago broker I knew socially telling me about a certain stock and pushing it.
I asked do you have any personally? He says yes. I ask what price did you pay? and his response was
Zero as the company gave him/his firm stock in return for promoting their company!!!! This was a mining related small cap but you get the idea.

I'm not saying OZL does this but it makes you take a step back and say what sort of preferential treatment are brokers getting in return for pushing certain stocks???
So basically Morgans may not be getting preferential coverage of the stock and Citi may be.
