Did take the 5 seconds to look it up, LOL. Yeah it looks like the division from Blackstone which become Blackrock wasn’t similar to JPMorgan spinning out Morgan Stanley. Have a nice day.
They were started as separate companies. The Blackrock guy went to Blackstone for seed money and owned a good chunk of BR for a while, but not the same thing. They’ve been completely separated for three decades at any rate (vs just a handful of years with partial ownership). Their strategies have never had any overlap.
