Citadel CEO Ken Griffin could easily be considered the top dog in finance right now. The hedge fund saw a record $16 billion in profits for clients last year, beating the rest of the hedge fund industry.
That surpasses the $15 billion John Paulson generated betting against subprime mortgages in 2007. All together, the top 20 hedge funds generated $22.4 billion in post-fee profits, Citadel included.
