My absurd approach to analyzing and valuating GS

I know, I know. What purpose could analyzing GS' depository affiliate GS Bank first have for my overall analysis of the parent corporation? None. I think of it as a bottom-up approach where I randomly chose to analyze GS Bank first. Big whoop. I will be moving up the entire corporate ladder though and getting into the nitty gritty as much as possible. In the meantime, I will be fascinated with the route I've embarked on. GS Bank is an oddball in the world of depository institutions. It's not as established as JPM nor does it have the street presence of Citi or Wells Fargo.
